If you have a dog which is subject to breed discrimination, such as a Rottweiler or any type of Pit Bull, you should consider having its temperament tested by the American Temperament Test Society. If any friends or family express fear of your dog, then you can tell them about his score and what they should expect from your dog. ATTS holds testing sessions for dog clubs around the country. Check out their schedule.
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. The test simulates a casual walk through the park or neighborhood where everyday life situations are encountered. During this walk, the dog experiences visual, auditory and tactile stimuli. Neutral, friendly and threatening situations are encountered, calling into play the dog's ability to distinguish between non-threatening situations and those calling for watchful and protective reactions.
