Pitbull-Type Dogs Achieve Excellent Temperament Scores

According to the latest ATTS breed temperament test data, the unique breeds that are commonly included in the modern pitbull-type category (such as the American Pit Bull Terrier, American Staffordshire Terrier, and the Staffordshire Bull Terrier) have achieved excellent temperament scores - scoring in the top 23% of all breeds tested. Not only do pitbull-type dogs have excellent temperament scores, they are also successful as service dogs, therapy dogs, K9 police dogs, and as family pets - validating their status as outstanding canine citizens in millions of U.S. households. Furthermore, the ATTS (American Temperament Test Society, Inc.) data reflects similar conclusions by scientific studies about the positive temperament of pitbull-type dogs while also providing further evidence that the behavior, trainability, and overall disposition (all factors related to temperament) of pitbull-type dogs is excellent. The temperament test scores and the summaries of several scientific studies on breed aggression and temperament are provided below.

"America's Dog"

​While all dogs are individuals, temperament test data, scientific studies, and the growing popularity of pitbull-type dogs all confirm that as a group, pitbull-type dogs are overwhelmingly successful as loving companions in millions of U.S. households. In fact, pitbull-type dogs have been popular in the U.S. going as far back as World Wars 1 and 2 when they were proudly called "America's Dog" and prominently featured as national mascots on military recruitment posters. Their excellent temperament and growing popularity are just a few of the many reasons why it's really no surprise that discriminatory dog bans (aka breed-specific legislation or BSL) that target dogs labeled as "pitbulls" have become exceedingly unpopular and are a trend in decline.
The ATTS test focuses on and measures different aspects of temperament such as stability, shyness, aggressiveness, and friendliness as well as the dog’s instinct for protectiveness towards its handler and/or self-preservation in the face of a threat. The test is designed for the betterment of all breeds of dogs and takes into consideration each breed’s inherent tendencies.
