                  Current Year 2015: 3 dog bite fatalities (updated 2/4/15)

1Maryland, January 7, 2015 in Frederick County, Maryland. 87-year-old man killed by pit bull while disassembling his Christmas tree (Read more).

2.  Florida, January 19, 2015 in Brooksville, Florida. 18-month-old boy killed by two family pit bull type dogs. Reports indicate that the attack occurred on the front porch where the child was playing while being watched by his 51-year-old grandfather.  Apparently, the grandfather witnessed the attack and assumedly tried to stop it, but was unsuccessful at preventing this fatality.

3.  Iowa, January 22, 2015 in College Springs, Iowa.  A 7 y.o. boy was the victim in this instance, killed by two family, pit bull type dogs.  Another 10-year-old boy in the same household may have been attacked and injured these same dogs 4 months prior to this incident.


The reader is directed to the dog bite fatality page on Wikipedia for the most scholarly, objective and comprehensive information on this topic.

Below, I will state the general concerns I have with regard to the reporting of statistics on fatal dog attacks by others on some websites.

  • First, some authors have strong biases against pit bull type dogs.  As such, these authors present dog bite fatality data that are “cherry picked” for the purposes of promoting a campaign which unquestionably demeans pit bull type dogs.  Such bias reporting obviously impacts the Fatal dog attackperception lawmakers and others have about pit bulls.  It appears that some webmasters have as their mission in life to demean the pit bull as much as possible and they use the internet to accomplish this.  Some webmasters choose to ignore the fact that not all pit bulls are dangerous by nature.  Honorable Americans have owned pit bulls, including Thomas Edison, Theodore Roosevelt and many others.
  • Second, the accuracy of data on fatal dog attacks depends on the validity and accuracy of facts about the incident as reported in news stories by the journalists who write the stories.  Webmasters depend on this information to create the content on their sites, yet the extent to which the information published is independently verified remains dubious.  Generally, the information is taking on face value. This may be problematic for a number of reasons. Particularly significant is the information reported about the breed of dog involved.  Occasionally, mistakes in correctly identifying the breed of dog(s) involved in a fatal attack happen (see problems with pit bull terrier identification). Likewise, other data collection techniques (animal control reports, police reports, witness observation) used for breed identification purposes in fatal dogs attack investigations may  be flawed because of problems inherent with accurate breed identification through visual means.
  • Third, because mistaken breed identity may occurs, numbers may be inflated for certain kinds of dogs, such as pit bull type dogs.
  • Fourth, it is important to note that a pit bull is not a breed of dog.  Instead, the term “pit bull” only describes a dog that has an appearance similar to a American Pit Bull terrier or American Staffordshire terrier.   In some cases a dog identified as a pit bull, based on its physical appearance, may be genetically similar to the American Staffordshire Terrier (AKC recognized) or an American Pit Bull (UKC recognized), but in other cases the dog is genetically dissimilar.
  • Fifth, the reader should note the incidences of fatalities listed on any website may not represent every case in the United States where death was caused by a dog attack. It is conceivable that some fatal dog attacks in the United States go unreported and never make news headlines, particularly in rural areas.

Finally, the fatalities reported on many websites may not be a direct result of injuries sustained from a dog attack. For example, in some dog bite fatalities the primary cause of death is secondary to bite injuries caused by an attack.  Examples include caradic arrest, freezing to death after falling unconscious following an attack, rabies, septicaemia, infection or falling on head as a result of being attacked.  For example, I recall a reported incident in March 2010 incident in Lucknow, South Carolina involving a 65-year-old lady.  Several websites reported this as a dog bite fatality caused by a pit bull attack, but subsequently the autopsy indicated a fatal heart attack was the primary cause of death (presumably from the stress of the attack). Also, note that a human fatality can be caused by the behavior of a dog that does not involve aggressive intent (e.g. smothering). Click here for medical perspective on the causes of death as a direct result of the dog attack. aablackdoghead
