Re: Evaluation of the dog bite to Ken Schweibish

 

Dear Ms. Vint and Mr. Goldberg,

 

            This report provides feedback to you regarding my opinions about the incident involving the dog bite injury inflicted to Ken Schweibish (referred to herein as Òthe incidentÓ). You have retained my services to analyze this matter for the purposes of expressing an opinion about the dog which inflicted this injury.

 

            With this understanding, I have undertaken or reviewed the following: (1) Interview with Ken Schweibish and examination of his dog in his home on March 11th, 2003; (2) Interview with Gloria Bender in her home and examination of her dog on March 11th, 2003; (3) Telephone interview with Craig Podell on Saturday, April 12th, 2003; (4) Site inspection on March 11th, 2003 of the location where the incident happened, a dog park facility named the ÒBark ParkÓ; (5) Follow-up examinations and interviews with Ken Schweibish on two occasions in April, 2003 to further review his version of the incident and further examination of the bite wounds to his right forearm; (6) Follow-up phone conversations with Schweibish to further elucidate his version of the incident; (7) Review of the photographs showing canine teeth measurements of the dog owned by Schweibish; (8) Review of the photographs of the bite injuries to the right forearm of Schweibish taken shortly after the incident happened; (9) Other miscellaneous discovery, such as interviews conducted by Terri Vint, and the medical records on Schweibish.

 

            Based on my scrutiny of the above-mentioned material, in this report I will state the findings and opinions I have reached.  First, I will describe how the incident happened.  Second, I will state the assumptions I have used that form the bases for my opinions.  Next, I will provide discussion of the issues most germane to the task of  determining which dog bit Schweibish.  Last, I will state my conclusions. 

 

I. Background

 

            The incident that led to the injury of Schweibish occurred in late afternoon April 22nd, 2002 at a facility called the Bark Park in Calabasas, CA.  Bark Park is an off lead, fenced-in ÒdoggyÓ park of considerable size.  Figure 1 shows a section of this park.  Bark Park is similar to the many other so-called doggy parks in the Los Angeles area in that dog owners take their dogs to these parks of this kind for exercise and social interaction.  While in the park dogs have the opportunity to interact and socialize with other dogs and people without restraint.  Many of the people who utilize this park are regulars in that they know each other and they know each other's dogs.  Accordingly, dog owners who regularly patronize the Bark Park have familiarity with the behavioral patterns and habits of many dogs that use this park. 

 

            The following 4 people are significant to my analysis either because they or their dog were present at the park when the incident happened, or because they were involved in the incident: Craig Podell, Gloria Bender, Ken Schweibish, and a person named Dan.  Podell, Bender and Schweibish were regulars of this park along with their dogs: (1) a Great Pyrenees, Rocky, owned by Schweibish; (2) a Rottweiler, Mac, owned by Bender; (3) a Dingo named Jersey owned by Podell, and (4) a husky-like dog, named Icon, presumably owned by Dan.

 

            Neither Dan nor Icon were available for interview or examination at the time of this writing. The Dingo owned Craig Podell was not involved in the incident.

 

            Rocky

 

            Rocky was a large, 2 year-old reproductively intact, male Great Pyrenees who weighed approximately 110 lbs.  Schweibish says Rocky was in good health. He appeared in good health at the time of my examination. Rocky has occasionally taken part in dog shows, and according to Schweibish, usually without incident.  During my examination of Rocky, he did not display any signs indicating aggressive tendencies towards humans.  He did not display tendencies of dominance.  He accepted my handling and physical manipulation without incident. He reacted with normal territorial barking and charging, but without growling or snarling, when I approached and provocatively banged on the front gate of the Schweibish property. Schweibish confirmed past aggressive displays by Rocky towards other dogs.  However, he claims that Rocky only became aggressive towards another dog when another dog tried to mount him.  Schweibish asserts that Rocky was generally well behaved and non-aggressive while at dog shows with the possible exception of one incident.  On the other hand, Podell and Bender both adamantly assert that that Rocky was considerably more aggressive and dominant to dogs than Schweibish would lead one to believe. Prior to the incident, Rocky knew Icon and Mac and generally tolerated these dogs during his encounters with them. 

 

            The distance between RockyÕs two upper canine teeth are shown in Figure 2 and Figure 3.  Figure 4 shows the distance between RockyÕs lower canine teeth. These photographs were recently taken at a veterinary hospital.  The measurements are as follows: 

 

            Distance between RockyÕs upper canine teeth: 2 & 3/16 inches.

 

            Distance between RockyÕs two lower canine teeth: 2 & 3/16 in.

 

            Mac

 

            Mac is shown in Figure 5. This 8 year-old neutered female Rottweiler impressed    me as a submissive dog towards humans. She appeared to be healthy, friendly and temperamentally sound. Bender says Mac was in good health at the time of the incident. At the time of my examination, MacÕs weight appeared to be approximately 85 lbs.  Mac showed no reactivity when I intentionally banged on the front door of the Bender residence. I encountered no aggressive resistance during my attempt to physically manipulate Mac for the purpose of taking measurements of her teeth.

 

            During my questioning of Bender, I also attempted to gather information about Mac's ÒpolicingÓ behavior. Apparently, according to Schweibish, while at the park, Mac had the tendency to insert herself between dogs that became engaged in emotional, aggressive-like, encounters.  Mac's tendency to display this kind of behavior was confirmed by Bender, but she dismissed the notion that it was ever done with aggressive intent.  Craig Podell also confirmed that, at times, Mac had the tendency to engage in this kind of behavior. Podell also stated that Mac was non-aggressive towards other dogs and very friendly towards people. Bender cogently emphasized that Mac was a very friendly dog and had never displayed any aggression towards a human or towards another dog.  My cursory examination of Mac at the Bark Park confirmed what Bender told me in that Mac appeared well behaved and non-aggressive towards other dogs and people who were present.

 

            Mac was placed into and accepted a supine position during my attempt to measure the distance between her two upper and two lower canine teeth. The distances were as follows:

 

Distance between MacÕs upper canine teeth 2 inches;

 

Distance between MacÕs lower canine teeth 1.5 inches.

 

 

             Distances between the teeth were recorded with a tape measure that was placed against MacÕs teeth while she was placed into a supine position.  Measurements were repeated to ensure accuracy. Teresa Vint assisted in the measurement procedure. Vint should be able to confirm the measurements taken by Polsky, as stated above. Photographs showing these distances were not taken, however.

 

 

            Icon

 

            Relatively little is known about Icon, the husky-type dog owned by Dan. Craig Podell and Schweibish both characterized Icon as dog aggressive.  I would estimate that Icon's weight to be approximately 40 lbs based on the typical breed characteristics of husky dogs.  Further, based on the assumption that Icon was a husky-type dog (independently confirmed by Podell, Bender and Schweibish), it would be fair to assume that the distance between Icon's two upper canine teeth and two lower canine teeth were considerably less than the distances between these same teeth for either Rocky or Mac. I would estimate a distance of approximately 1.5 in between IconÕs the upper canine teeth and a distance of approximately 1.0 in. Ð 1.25 in. between IconÕs lower canine teeth.

 

II. Description of the Incident

 

            According to Podell and Schweibish, they along with Bender, were seated on a bench approximately 6 ft. southeast from where the incident occurred.  Figure 6 shows a photograph of the bench and the area of the park where the incident happened.  Specifically, the incident happened in front and slightly to the east of the bench.  The bench is facing north.

 

            Note that on the day of the incident, Rocky was involved in two prior skirmishes with Icon. The first skirmish happened approximately 25 minutes beforehand and the second preceded the incident by about 5 minutes.  Both skirmishes were momentary and did not resulted in injury to anyone. According to Schweibish, things appeared to have settled between Icon and Rocky prior to the start of the third skirmish (i.e. the incident in question) which involved Rocky, Icon, Mac, and secondarily, possibly one or two other dogs, according to Podell. 

 

            According to Schweibish, the incident started when Icon came from behind the bench and engaged Rocky in an aggressive manner (herein referred to as ÒPhase 1Ó). Rocky was standing facing east, 3 Ð 5 feet in front of Icon.  According to Schweibish, when he noticed this happening he immediately left the bench and approached Rocky from the right.  Schweibish says he then immediately positioned himself in front of Rocky and used his hands to push Rocky backwards away from Icon (herein referred to as ÒPhase 2Ó).  Figure 7 shows the approximate position of Schweibish relative to Rocky during his initial approach (Phase 1) and Figure 8 shows Schweibish in the approximate position while pushing Rocky away from Icon (Phase 2).  During this phase, Icon was restrained by Dan according to Schweibish.  He makes no mention of the presence of another dog.

 

            Next, according to Schweibish, he quickly moved to RockyÕs left side in a kneeling position and put his left arm around the chest of Rocky while simultaneously pulling backwards on RockyÕs neck with his right hand (herein referred to as ÒPhase 3Ó). Figure 9 illustrates the approximate posture Schweibish says he was assuming.

 

            Shortly after Schweibish assumed the posture shown in Figure 9, he claims Mac suddenly came charging from his left in what he believes may have been an attempt to attack Rocky.  He is unsure if Mac was successful in biting Rocky.  He says when this happened he tried to thwart the advance of Mac by pushing Mac back with his left arm. According to Schweibish, this was momentarily successful.  However, Mac immediately came forward again and according to Schweibish seized his right forearm, which as illustrated, was positioned approximately on the cervical part of RockyÕs spine.

 

            Next, Schweibish says Mac let go of his arm but then immediately seized it again with considerably more force and pressure.  Schweibish says that he felt intense pressure with MacÕs second bite.  Schweibish then believes Mac was pulled from him resulting in a tear to his right arm.  In the approximate 3 Ð 6 seconds this was happening, Schweibish believes Dan continued to restrain Icon who was now approximately 10 ft. away, directly in front of Rocky.  The incident ended at this point.  Both Podell and Schweibish say the incident in its entirety lasted about 10 Ð 12 seconds. 

 

            Moreover, although not certain, Schweibish believes that his right arm probably remained flush on the back of Rocky only momentarily after he was bitten the second time by Mac.  According to Schweibish, profuse bleeding did not start immediately.  It started about 30 sec. later after pressure was applied to the areas where Schweibish was bitten.  He remembers seeing blood on Rocky only in the area of his head and ear. During the incident he says Rocky was bit in the left ear but is uncertain as to whether Mac or Icon inflicted the injury.  Bite wounds to Schweibish's right arm, including the tear, are shown in Figure 10 and Figure 11.  Distances between the wounds are also shown in these photos.  Figure 12 shows a single puncture near the wrist on the top of the arm.

 

            Aspects of Podell's version of the incident are different.  For example, he believes that Icon, Rocky, and Mac were already engaged in what he terms "mixing it up" (possibly with some other peripheral dogs) when he and Schweibish left the bench to intervene.  He makes no mention of Mac suddenly charging from a distance into Schweibish.  He places Mac to the left of Schweibish.  He believes Schweibish was bending.  He believes Schweibish put his arm between the dogs and as a result was bitten.  However, Podell is uncertain as to which dog, or dogs, bit Schweibish. He says he separated Mac from the other dogs by grabbing MacÕs rear legs and pulling her away Òlike a wheel barrel.Ó

 

III. Assumptions

 

            Based on the above, and on my expertise on aggressive behavior in companion dogs, below I will state the most important assumptions used in forming my opinions.  These assumptions are as follows:

 

1. Three dogs were involved in the incident: Rocky, Icon and Mac;

 

2. The incident was very short-lived: it lasted approximately 10 seconds. Initial attempts at intervention by Podell and Schweibish happened immediately after the incident started. 

 

3. The were three phases to the incident.  During the different phases, Rocky, Icon and Mac were all close enough to Schweibish to bite the right arm of Schweibish.  In particular, Mac was proximate to Schweibish during Phase 1.

 

4. Podell does not know which dog bit Schweibish. Therefore, the only eyewitness to the bite(s) was Schweibish;

 

5. During the entire incident, Mac was positioned to the left of Rocky and Icon was in front of Rocky;

 

6. Schweibish started his intervention before Podell started pulling Mac away. Further, Podell began pulling Mac shortly after Schweibish repositioned himself in a bending position on the left side of Rocky (Phase 3);

 

7. Schweibish was bitten by a dog that at the time of the bite had to have been positioned perpendicular to the right arm of Schweibish. In other words, the bite(s) could have only happened during the time the right arm of Schweibish was perpendicular to a dog.

 

8. The right arm of Schweibish was positioned perpendicular to at least one of the dogs at the beginning of the incident (Phase 1), or when Schweibish was pushing Rocky (Phase 2), or after Schweibish repositioned himself besides Rocky (Phase 3);

 

9. Distances between the upper and lower canine teeth for Mac and Rocky, as well as the distances between the bite wounds on the right forearm of Schweibish have been measured with a fair degree of precision;

 

10. The incident ended by Podell pulling Mac away from Rocky;

 

11. Mac possessed a markedly non-aggressive temperament towards people. Rocky and Icon possessed greater tendencies than Mac to display aggression towards other dogs.  Rocky possessed a non-aggressive temperament towards people in most circumstances. Mac possessed an increased potential for aggression towards other dogs during the instances when she engaged in patrolling or ÒpolicingÓ behavior.

 

12. During the incident, Mac, Rocky, and Icon were all in a heightened state of emotional arousal conducive for the display of aggressive behavior, including biting behavior.

 

13. Bite wounds on the right forearm of Schweibish show a 2 inch separation between a relatively large puncture (with a slight tear of approximately 1/8 in.) and a tear of approximately 3 in. in length (Figure 10).  Two other visible wounds are located towards the wrist on the bottom of the right forearm (Figure 11). The distance between these wounds is slightly less than 1 inch.  The single puncture on the top of the arm near the wrist (Figure 12) is associated with the aforementioned wounds on the bottom of the arm.

 

14. Based upon the alignment of the two wounds which show separation by a distance of 2 in. (i.e. the tear and the puncture), the direction of the tear on the right arm of Schweibish moves from the outside to the inside.

 

IV. Issues relevant to determining which dog bit Schweibish

 

In order to determine which dog(s) inflicted the bite(s) to Schweibish, the following issues must be analyzed:

 

1.  The position of Rocky, Mac and the Icon relative to the right arm of Schweibish during all phases of the incident. Positions are needed in order to determine which dogs were perpendicular to Schweibish.

 

2. The distance between the bite wounds relative to the distance between the upper canine teeth of each dog;

 

            3. The significance of the tear across the arm of Schweibish;

 

4. The temperament of the dogs and their past behavior.

 

         Issue #1: Position of the Dogs

 

            According to Podell, Rocky, Icon and Mac were Òmixing it upÓ when Schweibish started his intervention. According to Podell, Schweibish simply went between the dogs. He does not know of the actions of Schweibish during Phase 1 or Phase 2.

 

            The versions of Schweibish and Podell differ in one important aspect.  Namely, in contrast to Podell, Schweibish does not place Mac near him at the beginning of the incident (Phase 1). Rather, according to Schweibish, Rocky and Icon were face-to-face, both aggressively aroused, and he moved towards these dogs in an attempt to push Rocky away from Icon before repositioning himself, bending on the ground, to the left side of Rocky. According to Schweibish, this is the point when Mac came running into the mix (Phase 3). Tracy Barker and Joseph Ross also witnessed Mac come running into the mix.

 

            Consistent with Schweibish, Podell places Mac to the left of Rocky, and he says Schweibish was probably bending.  Likewise, Podell believes Schweibish was restraining Rocky in a matter similar to what Schweibish describes.  Thus Podell's account confirms in part what Schweibish says.  However, as noted above, Podell is unable to provide much detail about the positioning of the dogs or the positioning of Schweibish prior to Stage 3 other than his belief that Icon was in front of Rocky at the start of the incident.

 

            If SchweibishÕs version is believed, then Mac was definitely not proximate to Schweibish during Phase 1 or Phase 2 and therefore could not have inflicted injury.  On the other hand, if Podell is believed, then Mac was proximate to Schweibish during all phases of the incident.

 

             For this analysis, rather than passing judgment on which version is correct, I instead will focus on determining which dogs were perpendicular to the right arm of Schweibish during the various phases of the incident.  This is the most germane question.  Thus I will assume that Mac was in fact proximate and in the mix, but she may not have been perpendicular.

 

            My findings are as follows:

 

            1. Given that Mac was located to the left of Rocky and that Icon was located in front of Rocky, then when Schweibish first approached Rocky (Phase 1), it seems clear that Icon and Rocky were the only dogs positioned perpendicular to the right arm of Schweibish; 

 

            2. During Phase 2, given the location of all dogs relative to Schweibish, Mac was the only dog perpendicular to the right arm of Schweibish;

 

            3. After Schweibish repositioned himself into a bending posture (Phase 3), Mac was the only dog perpendicular to the right arm of Schweibish.  Fox example, Icon was facing Rocky and Rocky's head was pointing away from Schweibish towards Icon, thus making it impossible for either dog to be perpendicular to the right arm of Schweibish;

 

            4. During Phase 1, the right arm Schweibish probably became momentarily perpendicular to Icon, thus making it possible for this dog at this point in time to inflict a bite to Schweibish.  If this did happen, then it probably occurred just when Schweibish was attempting to reach for Rocky immediately after his approach. This is consistent with Podell's belief that Schweibish inserted his arm between several dogs that, in PodellÕs terms, were Òmixing it upÓ.

 

            5. Icon was not positioned perpendicular to the right arm of Schweibish either during Phase 2 or Phase 3.  Assuming that Icon remained positioned in front of Rocky during the entire incident, then during these latter phases the right arm of Schweibish was clearly not perpendicular to Icon.  

 

            Table 1 provides a summary of these findings.  Table 1 indicates which dogs were perpendicular to the right arm of Schweibish during each phase of the incident.  In sum, findings show that: (a) Rocky and Icon were in this position only during Phase 1; (b) Mac was positioned in this manner during Phase 2 and Phase 3. 

 

            It is of significance to note that Schweibish believes that Mac bit him during Phase 3 Ð not during Phase 1 or Phase 2. This finding lends credence to his belief.

 

 

 

        

Issue #2: Distance between the bite wounds relative to the     distances between the canine teeth.

 

            Four distinguishable wounds were present on the arm of Schweibish.  Specifically, there were two small punctures, not very large in diameter, spaced slightly less than 1 in. apart on the inside right forearm near the wrist. Next, there was a single large diameter puncture wound (with a very slight tear) on the topside of the right forearm exactly 2 in. away from an approximately 3 in. tear across the right-central forearm.  The wound from the 3 in. tear was quite obvious.  Other puncture wounds on SchweibishÕs arm may have been present; however, these were not clearly visible at the time of my examinations.

 

            It is significant to note that the larger puncture wound, spaced 2 in. away from the 3 in. tear, exactly corresponds with the distance between the upper canine teeth of Mac. This distance does not match the distance between the upper canine teeth of Rocky, nor does it match the much smaller distance between the upper canines for Icon.

 

            The distance between the two smaller puncture wounds near the wrist clearly does not match the distance between the canine teeth for either Mac or Rocky.  On the other hand, they may approximate more closely the distance between the lower canine teeth for Icon. The single puncture of the top of the arm near the wrist (Figure 12) is likely to be the contra lateral component of the two smaller wounds on the bottom of the wrist (Figure 11).  In the absence of specific measurement on Icon, this must be treated as speculative, however.

 

            In sum, there is remarkable correspondence between the distance separating the two most distinguishable bite wounds on Schweibish (i.e. the large puncture and the 3 in. tear) and the distance between the upper canine teeth for Mac.  Other visible puncture wounds present suggest that more than one bite may have occurred during the incident.  Icon rather than Rocky or Mac most likely were inflicted these wounds because of their size and spacing between them.

 

Issue #3: The significance of the tear across the arm of Schweibish.

 

            As noted, one distinguishable wound consisted of a tear across the top of the arm of Schweibish approximately 2 in. from a large puncture wound.  Moreover, of considerable significance, is the fact that an approximate even alignment exists between the one end of this tear and the puncture wound.  If one uses this alignment, then it appears that the direction of the tear moves from the outside of the arm to the inside.  That is, from right to left.  Given this, the dog that inflicted this injury must have been positioned to the left of Schweibish.

 

            This is significant because according to Schweibish, Mac came from his left and seized his arm. Podell confirms Mac's position to the left of Schweibish and Rocky.  Podell says he pulled Mac from the where the dogs were Òmixing-it-upÓ.  Using this information, it seems reasonable to conclude that the tear on the arm of Schweibish was caused by Podell pulling Mac from Schweibish in a direction from right to left just when Mac had the arm of Schweibish in her mouth.  Moreover, given that Mac was positioned to the left of Schweibish, and given that the tear was located to the right of the puncture wound, it seems likely the upper right canine tooth of Mac did this damage.

 

            In sum, given the position of Mac relative to Schweibish and that: (a) Podell says Mac was to the left of Schweibish when he pulled Mac away, and (b) that tear appears to move from outside to the inside, it seems reasonable to conclude that the tear happened because Mac had the arm of Schweibish in her mouth just when she was being pulled from Schweibish by Podell. The findings do not support any other explanation.

 

            Issue #4: The temperament of the dogs

 

            The owner of Mac, Gloria Bender, stressed that Mac was a passive dog, well tempered, and that she had never displayed any aggression to any person.  My observations of Mac during my inspection in the Bender home and at the Bark Park confirm this.  Moreover, Bender supplied me with the names of several people who were familiar with Mac and who could speak to MacÕs well-tempered and non-aggressive nature.  I chose not to contact these people because I felt the input from these people would have added little to my analysis. I believe that Mac was indeed very well tempered and non-aggressive.  I believe MacÕs propensity to inflict a bite onto a human with intent was nil.

 

            However, this is not to say that Mac did not have the potential of becoming aggressively aroused towards other dogs in certain circumstances.  Specifically, I am referring to the kind of circumstances in the Bark Park that occasionally arose when two or more dog displayed hostility towards each other.  When this happened, Podell, Schweibish and even Bender herself acknowledge that Mac had an interest in Òpolice workÓ.  That is, Mac would approach and intervene.  Bender says Mac would place her body between the dogs is a non-aggressive manner. Schweibish says that the interventions by Mac had more of an aggressive nature to them, however. The motivation for this relatively odd behavior is obscure: it may have to do with her Rottweiler ancestry (e.g. a breed developed for herding cattle).  Whatever the motivation, I believe this sort of behavior established a foundation for aggressive responding in Mac towards other dogs, particularly if the dogs were already acting aggressively towards each other.

 

            I mention this, because Bender, suggested that it would have been impossible for Mac to have bit Schweibish because Mac had never displayed aggression towards a human. This may very well be true. To a layperson and certainly towards Bender, it would appear that Mac lacked the potential for aggressive responding towards a human.

 

            However, I believe the circumstances created by the aggression between Icon and Rocky were sufficient to arouse aggressive tendencies in Mac.  I believe that when the incident began, Mac took notice from wherever she might have been located. The fact that Podell and Schweibish initially place her in different locations is not that important.  In contrast, what is important is that both Podell and Schweibish place Mac proximate and to the left of Schweibish during Phase 3, and both say she was acting aggressively.  At that point, she became involved in the fight.  Her focus was on Rocky and not on Schweibish.  She was motivated to bite Rocky and not Schweibish. Schweibish was bitten unintentionally in MacÕs attempt to get at Rocky.  In short, I do not believe that Schweibish was the target of MacÕs aggression.  Rather, the dogs were fighting and his right arm happened to be in the way.

 

V. Conclusions

 

            1.  All three dogs were aggressively aroused at the time of the incident and all were motivationally capable of biting Schweibish.

 

            2.  It seems certain that Mac inflicted the bite associated with the tearing injury and that this happened during Stage 3. During this time, she was perpendicular to Schweibish (given the position of Schweibish and the fact that Mac was to the left) and she was aggressively aroused.  Moreover, the distances between the wounds exactly match the distance between her upper canine teeth. 

 

            3. Less certainty exists regarding the role of Icon played in inflicting a bite(s). Note, however, in Phase 1, Icon was properly positioned about 3- 5 feet from Schweibish, he was aggressively aroused, and the distance between two small puncture wounds most closely approximate the distance between IconÕs lower canine teeth.  Further, these punctures are on the underside of the wrist of Schweibish, which is the area one would expect the lower canines to impact.  The single puncture on the top part of the wrist may be the contra lateral component of this bite.

 

            4. It seems likely that none of the bites were inflicted by Rocky.  First, distances between RockyÕs teeth do not match distances between any of the visible wounds on SchweibishÕs arm.  Second, if Rocky did bite Schweibish, it could have only happened during Phase 1.  According to my findings, during Phase 2 and Phase 3, Rocky was not positioned perpendicular to the right arm of Schweibish for a bite to have occurred (see Table 1).  If Rocky bit Schweibish during Phase 1, then one needs to reconcile this with the lack of blood on RockyÕs back (i.e. the area in contact with SchweibishÕs arm).  I speculate that If Schweibish was bitten by Rocky during Phase 1, then itÕs likely that his arm would have immediately shed some blood and this blood would have been transferred to the coat of Rocky by the time he placed his right arm on the back of Rocky during Phase 3.  Note that Schweibish bled rather heavily as a result of his injuries.  However, Schweibish says the heavy bleeding did not start until after he became disengaged from Rocky.

 

VI. Caveats

 

            Careful consideration needs to be given to the following:

 

           1.  First, my findings are derived in large part from the version of the incident provided by Schweibish.  It stands to reason that he would be prone to present a version that disallowed the possibility of Rocky biting him.  However, it should be importantly noted that Podell has corroborated important parts of SchweibishÕs version.  On the other hand, some of it cannot be corroborated.  For example, crucial to my analysis was the position of Schweibish relative to the position of each dog. Based on this, I reconstructed this very short-lived incident into 3 phases.  However, I have no way of knowing the validity of this conceptualization.  As stated, it is based almost entirely on the version provided by Schweibish.  However, if his version approaches the truth then my conceptualization is valid and my findings and conclusions are consistent with knowledge in animal behavior. 

 

            2. Two important assumptions in my analysis are (a) Mac was proximate to Schweibish during the entire incident, and (b) the various phases of the incident have been accurately reconstructed.  Note if the assumption concerning MacÕs proximity were not correct (i.e. SchweibishÕs version is believed and not PodellÕs), then it would not be sufficient to change my opinions.  However, if my assumption concerning the various phases was faulty, then my analysis needs to be seriously questioned.

 

            3. Two troublesome issues remain:

 

                        (a) During Phase 3, why did Mac seize SchweibishÕs right arm and not the left? The right arm was furthest away, and although clearly perpendicular, it was not readily available for seizure because it was resting flush on the back of Rocky.  The body of Schweibish was also partially blocking access to his right arm.  I reconcile this with the facts that: (1) the target of MacÕs aggression was not Schweibish but rather Rocky, and (2) Mac was surely not a people-aggressive dog; therefore he left arm should not have been a target.

 

                        (b) If the incident lasted only 10 seconds, then how did Schweibish have the time to move from the bench to the front of Rocky who was 6 feet away (Phase 1 and Phase 2) and then turn and reposition himself on the left side of Rocky (Phase 3)? 

 

            4.  I did not have the opportunity to examine Icon or interview Dan.  I do not know if discovery collected from these sources would have shaped my opinion in any way, however.  On the other hand, if Dan did witness Schweibish get bit, then certainly this would be very important information.

 

            5.  My analysis is based in large part on the recall abilities of Schweibish and Podell.  Given that my interview with them took place about a year after the incident, itÕs conceivable that details have been forgotten.  In fact, both Podell and Schweibish could not answer certain questions because of this.  At times SchweibishÕs appeared nervous but this was probably due to the disturbing nature of the whole matter.  On the whole, Ken Schweibish was extremely cooperative and accommodating.  On the telephone Craig Podell was also cordial and he sounded very sure of himself.

 

            6. One must recognize that my findings are based in part on the visible wounds present at the times I examined Schweibish.  It is possible that some bite wounds were no longer visible at the time of my examination.  In fact, the wounds that were noticeable had already begun to fade.  Thus, its conceivable that bites inflicted by either Rocky, Mac or Icon were not detected.  Although I do not feel this is likely (based on my examination of the photos taken by Schweibish shortly after the incident and comparing them what was visibly noticeable at the time of my examination) one nevertheless needs to take this into consideration.

 

VII. Summary

 

            Given that all three dogs were in an motivational state of aggression, in order to determine the dog(s) was responsible for inflicting the bite(s) to Schweibish, the following available sources of information were most heavily relied upon: (1) The position of Schweibish relative to the position of each dog as the incident unfolded, and (2) The nature of wounds on the arm of Schweibish relative to the distance between the canine teeth of each dog.  Using this information, my findings may be summarized as follows:

 

            1.  Rocky probably did not inflict any bites to Schweibish. His positioning relative to Schweibish during Phase 2 and Phase 3 lends credence to this finding.  Moreover, blood was not found on the back of Rocky and the distance between his canine teeth do not match any visible wounds found on Schweibish, thus discounting the possibility that a bite(s) from Rocky happened during Phase 1.

 

         2. Mac inflicted at least one bite to Schweibish. The tearing nature of one of the wounds, the perpendicular position of Mac relative to Schweibish during Phase 3, and the actions of Podell during Phase 3, support to this conclusion. Specifically, the tearing on SchweibishÕs arm could only have been caused by the action of Podell pulling Mac from Rocky.  Of great significance is the 2 in. distance between the tearing wound and the large puncture.  This is an exact match with the distance between Mac's upper canine teeth, thus demonstrating with a reasonable degree of certainty that Mac inflicted this bite.

 

            3. Icon may have bitten Schweibish. The presence of two small adjacent puncture wounds near SchweibishÕs wrist approximate the distance between IconÕs lower canines, thus suggesting a bite may have been inflicted by Icon.  Given IconÕs position relative to Schweibish during Phase 1, this possibility cannot be discounted. 

 

            4. The bite from Mac (or Icon) did not happen with intent. This was a dogfight and Schweibish happened to be Òin the mixÓ.  I believe the focus of Mac was entirely on a Rocky. Her intent was to bite Rocky and not Schweibish.  I believe that Mac directed her biting to the head/neck area of Rocky (as is common for many dogs embroiled in a dog fight) and in the process mistakenly seized the right arm of Schweibish, which was flush on the neck and back of Rocky. The incident ended and disengagement occurred as a result of Podell pulling Mac backwards, which resulted in a tear across the arm of Schweibish.  

 

            Sincerely,
