American Veterinary Medical Association data shows pit bull-type dogs identified in a disproportionate share of the most severe and fatal dog bite cases, but the AVMA’s own peer-reviewed breed list also names German Shepherds, Rottweilers, Chow Chows, Labrador Retrievers, and several other familiar breeds among the dogs most often behind serious bite injuries. No single breed explains every dog bite death.
Ask someone to name the most dangerous dog breed and pit bulls usually come up first. That reputation is not baseless, but it can crowd out a more useful question for parents, dog owners, and anyone bitten by a breed they never expected to be dangerous: what does the bite and injury data actually show?
Which Dog Breeds Cause the Most Bite Injuries?
Pit bulls are responsible for a disproportionate share of reported dog attacks on humans, as many as 82% by some estimates, despite accounting for only around 7% of the U.S. dog population. The American Veterinary Medical Association’s own review of bite data explains why: “If you consider only the… number of cases that resulted in very severe injuries or fatalities, pit bull-type dogs are more frequently identified [than other breeds].” In plain terms, a pit bull-type dog is not necessarily biting more often than other breeds; it is simply more likely to be the one identified in the worst-outcome cases. The CDC offers general guidance on reading a dog’s body language that applies no matter the breed.
Beyond Pit Bulls: The AVMA’s Full Breed List
A peer-reviewed 2014 breed list compiled by the AVMA’s Animal Welfare Division, drawn from real bite-injury reports, includes several breeds most people would not expect to see:
- Chow Chows
- Collie breeds (Bearded Collies, Border Collies, Rough Collies)
- German Shepherds
- Jack Russell Terriers
- Labrador Retrievers
- Mixed-breed and mutt dogs
- Rottweilers
- Spaniel breeds (Clumber Spaniels, Cocker Spaniels)
Labrador Retrievers, one of the most popular family dogs in the United States, and gentle-looking Collies and Spaniels are the entries that surprise most readers. The AVMA’s point is not that these breeds are secretly vicious; it is that bite risk depends more on an individual dog’s health, socialization, and situation than on breed alone, which is exactly why breed-neutral laws like Oklahoma’s hold every owner to the same standard.
Small Dogs and Children: An Overlooked Danger
Large, powerful breeds get the headlines, but small dogs cause real injuries too, especially to children. Behaviors like jumping, nipping at ankles, and snapping over food would never be tolerated from a large dog, yet owners often excuse the same behavior in a toy breed because of its size, a pattern common enough to have its own name: Small Dog Syndrome.
An adult can usually fend off a Chihuahua or Lhasa Apso; a toddler cannot. A few unsupervised seconds are often all it takes for even a small dog with no bite history to cause a serious facial or hand injury to a child too small to get away.
Small dogs create a second, less obvious risk underfoot: a dog darting between someone’s feet is a common cause of a trip-and-fall injury caused by a pet, particularly for older adults. If a child in your family has already been bitten, here is what to do in the first hours afterward.
Oklahoma Law Does Not Treat Any Breed Differently
Whatever the breed, Oklahoma’s dog bite statute applies the same way. Under 4 O.S. § 42.1, an owner answers for the full extent of the damages when their dog, unprovoked, bites or injures someone with a legal right to be there. The statute does not name or exempt any breed; a Chihuahua and a Rottweiler are judged by the identical standard. See how Oklahoma defines a dog owner’s strict liability for the rural exception and other details.
Homeowner’s and renter’s insurance usually covers a dog bite claim, though some insurers exclude specific breeds or cancel a policy after a bite. Clayton Hasbrook has practiced Oklahoma injury law since 2008, and he checks that policy language on every dog bite case our firm takes on. A dispute over how an insurer handled a claim can go to the Oklahoma Insurance Department.
Frequently Asked Questions
Which dog breed causes the most injuries?
Pit bull-type dogs top most estimates, but AVMA data also lists German Shepherds, Rottweilers, Collies, Jack Russell Terriers, Labrador Retrievers, Chow Chows, Spaniels, and mixed-breed dogs among the breeds most often involved in serious bites.
What dog breed causes the most deaths?
Pit bull-type dogs are identified more often than any other breed in the most severe and fatal cases, though multiple breeds appear across fatal-attack reports and no breed is entirely risk-free. When a mauling proves fatal, surviving family members can pursue what Oklahoma law allows a family to recover after a fatal dog attack, regardless of the breed involved.
Can small dog breeds hurt children?
Yes. Toddlers and infants cannot fend off even a small, excitable dog, and small breeds are also a common cause of underfoot trip-and-fall injuries.
Does a dog’s breed change who is liable for a bite in Oklahoma?
No. Oklahoma’s strict liability statute applies the same way regardless of breed, as long as the bite was unprovoked and the injured person had a legal right to be where it happened.
