Pitbull people will comment on the ATTS rating for Pitbulls. However, keep in mind that only 839 were tested to achieve a 86% rating but GSD's had 3133 tested for an 84% rating.
Wanted to mention that Rotties had 5545 tested for 83% rating.
SO since there appears to be so many well mannered Pitbull's, according to the Pitbull people, I'm surprised the numbers tested weren't higher for the pit. Always consider the size of the sample when looking at the percentage. Reason because if only one is tested for 100%, what does that really mean?
