The Facts of American Temperament Test re Pit bull type dogs

American Temperament Test:
The ATTS test, was NOT created to evaluate dogs for “pet” suitability.

In 1977, Alfons Ertel designed the American Temperament Test in hopes of creating a uniform temperament test for dogs. Of the 75 million dogs that populate the U.S. today,20 about 933 are tested per year (0.001% of all dogs).

And he was a printer, NOT an animal behaviorist. He owned German shepherds and was involved in the sport called shutzhund, which involves training dogs in the same manner in which police dogs are trained.

The ATTS was intended to test working dogs for jobs such as police work and it favors bold animals, i.e., dogs that face danger head-on without hesitation or fear.

Courage was a desirable trait, timidity an undesirable trait. Thus, German shepherds did much better on the ATTS than did collies and other timid breeds.

In fact, 95% of the dogs that fail the ATTS do so because they “lack confidence,” e.g., when approaching a weirdly-dressed stranger.

Of course, pit bulls are going to score well on a test geared toward aggressive behavior because these monsters were bred for the purpose of fighting and killing other pit bulls and nothing deters them, certainly not weirdly-dressed strangers!

The temperament data published by the group is not based upon scientific random sampling of any dog breed. It seems it would be virtually impossible to develop such a reliable study, as the base population source group is unidentifiable.

Due to the temperament data being objectively statistically unreliable, it is also highly misleading. Pit bull advocates frequently use this misleading data to point to the breed's good temperament and to advocate against breed-specific laws ("Pit bulls pass the ATTS test more often than beagles!").

Yet anyone one who has a minimal understanding of critical statistical analysis should be able to see that the ATTS "breed statistics" temperament data21 is essentially valueless.

The 12-minute test stimulates a casual walk through a park with a range of encounters. The test focuses on stability, shyness, aggressiveness and a few other factors. According to the group, the overall pass rate (the combination of all breeds) is 81.6%.22

Unlike the AKC's Canine Good Citizen test, no part of the ATTS test is performed without the dog owner present. It also fails to evaluate the most basic scenario that leads to aggression: How a dog reacts when it sees another dog.
