Pitbulls Achieve Excellent Temperament Scores

Recent temperament test data reveals that the breeds commonly included in the pitbull-type category — the American Pit Bull Terrier, American Staffordshire Terrier, Staffordshire Bull Terrier, and the American Bully — rank within the top 20% of all breeds evaluated for temperament. These results highlight their exceptional temperament, supporting their effectiveness in roles such as service animals, therapy dogs, K9 police dogs, and family pets — further underscoring their reputation as valued canine companions. Moreover, the temperament test results align with multiple studies on canine behavior that have reached similar conclusions about the positive temperament of pitbull-type dogs. Below, we summarize the results of temperament tests and findings from scientific studies on breed-specific aggression and behavior.

Scientific Studies 📑

Journal Of Veterinary Behavior

Is there a difference? Comparison of Golden Retrievers and dogs affected by breed-specific legislation regarding aggressive behavior

FINDINGS:
  • There were no significant differences in aggression between the legislated breed group (pitbull-type breeds, Dobermans, Rottweilers, and others) and the Golden Retriever control group.
  • "Comparing the results of golden retrievers and breeds affected by the legislation, no significant difference was found. A scientific basis for breed specific lists does not exist."

APPLIED ANIMAL SCIENCE BEHAVIOR JOURNAL

Human directed aggression in domestic dogs: Occurrence in different contexts and risk factors

FINDINGS:
  • Aggression is strongly linked to an individual dog's experience and environment — aggression is not a trait that can be associated with any specific breed.
  • The factors associated with increased rates of aggression were not breed-specific and included intact dogs (failure to neuter), a dog's age, and dogs subjected to punishment-based training methods.
  • "It would be inappropriate to make assumptions about an individual animal's risk of aggression to people based on characteristics such as breed."

Pitbulls Are Family 🐶

While all dogs are individuals, temperament tests, scientific studies on canine behavior, and the growing popularity of pitbull-type dogs collectively demonstrate that, as a group, dogs labeled as 'pitbulls' are great dogs and are loved as family members in millions of U.S. homes. Their positive temperament is one of the many reasons why pitbulls have been popular in the U.S. since at least World Wars I and II when they earned the title 'America's Dog' and were featured as national mascots on military recruitment posters. Their positive temperament and popularity are just a few reasons why it's really no surprise that breed-specific legislation (BSL), which targets dogs based only on their appearance or assumed breed regardless of behavior or responsible ownership, has become increasingly unpopular and is a trend in decline.
