DOG BITE-RELATED FATALITIES ARE EXCEEDINGLY RARE.
The interactions between dogs and humans are so numerous and complex that no one factor can be considered,
in isolation from any other factors, to be the sole cause.
There were 40 verified dog bite-related fatalities (DBRFs) in the US in 2014.1
They occurred within a human
population of 316 million and a canine population estimated at between 70 and 83 million.
National Canine Research Council continues to thoroughly investigate DBRFs using the same methodology
described in the comprehensive, ten-year study published December 2013 in the Journal of the American
Veterinary Medical Association.

INVESTIGATIONS TAKE TIME TO CAPTURE ACCURATE INFORMATION.
Number of fatalities:
In January 2015, the Preliminary Report on Dog Bite-Related Fatalities 2014 noted that 41 DBRFs were currently
being investigated. It has subsequently been determined that there were 40 DBRFs for 2014.
National Canine
Research Council investigations have found that two of the deaths initially believed to be DBRFs based on media
reports were ruled by the Medical Examiner to not have dog bites as either the immediate cause of death, nor
were dog bites listed as a contributory factor.3
Another death initially reported by the media to be attributed to stab wounds was ruled by the Medical
Examiner to be the result of dog bites.
Breed Identification:
In only 20% (n=8) of the cases of DBRFs was there any evidence that the dogs involved were purebred and/or
had a known pedigree.
In all the other cases, the dogs were either of unknown origins and/or genetics (n=29),
or were never located or identified by authorities (n=3).
Criminal Charges:
Criminal charges against a parent or dog owner were filed in 37.5% (n=15) of the 40 cases of DBRFs in 2014.
MULTIPLE FACTORS CONTINUE TO CO-OCCUR THAT ARE WITHIN THE CONTROL OF OWNERS.
The December 2013 study is the most comprehensive multifactorial study of DBRFs to be completed since the
subject was first studied in the 1970’s.
Covering all incidents that occurred during the ten-year period 2000 -
2009, it is based on investigative techniques and data developed by National Canine Research Council not
previously employed in dog bite or DBRF studies.
The study reliably identified seven factors potentially within the control of dog owners and caretakers that cooccurred,
in various combinations, in the overwhelming majority of DBRFs the authors examined:
The study, as had DBRF studies published previously, found no evidence that one kind of dog is more likely to
injure a human being than another kind of dog.
.
Four or more of the factors identified co-occurred in 80.5% of the incidents during the ten-year period studied.
Only very rarely (in 2.5% of the cases) was there only one factor identified. Serious and fatal dog bite incidents
are complex, multifactorial events.
Factor
Cases from 2000-2009 with
this factor present
No able-bodied person being present to intervene. 87.1%
The victim having no familiar relationship with the dog(s). 85.2%
The owner failing to neuter/spay the dog(s). 84.4%
A victim’s compromised ability, whether based on age or physical
condition, to manage their interactions with the dog(s).
77.4%
The owner keeping dog(s) as resident, rather than as a family pet. 76.2%
The owner’s prior mismanagement of the dog(s). 37.5%
The owner’s abuse or neglect of the dog
THE CONCLUSION OF EXPERTS: SERIOUS AND FATAL DOG BITE-RELATED INJURIES ARE
MULTIFACTORIAL.
Annual reports and detailed case histories considered in isolation will not enhance awareness of what the experts
have agreed on.
Minor annual fluctuations in co-occurrence of owner factors, or dramatic, one-of-a-kind case
histories may, in fact, obscure rather than enlighten. No single factor has been shown, in isolation from other
factors, to be the sole cause of a dog bite-related injury or fatality.
Professionals studying dog bite-related injuries,
even when venturing speculations regarding breed, have been remarkably consistent in their recommendation of
pet ownership and child safety practices directly relevant to prevention, and against regulating dogs on the basis
of breed or appearance.4

3. Cases erroneously reported by the media to be dog bite-related fatalities:
Rita Pepe, 93 years old, New Haven, CT.
On April 13, 2014, Rita Pepe was seriously bitten on the leg by a dog.
The Office of the Chief Medical Examiner
determined her death on May 25, 2014 to be from natural causes due to renal failure.
Nancy Newberry, 77 years old, Phoenix, AZ.
On March 14, 2014 the media reported that Nancy Newberry was “mauled” by a dog and “bled out from a dog
bite to the stomach.”
The Maricopa Medical Examiner ruled that Newberry “died as a result of advanced atherosclerotic cardiovascular
disease. Blunt force trauma of the head is a contributory factor.”
Dog bites were not found to be the cause of
death, nor a contributory factor.
