Just wanted to share an observation that seems to be what everyone is saying. No matter the size the dog has to be athletic is kinda what im getting from all this.. And all the pics that were posted. The dogs differed in size but all had good muscle tone and appeared that they could handle themselves. If the dog stands 20 inches at the shoulder but weighs 65lbs and solid muscle, which categor would it fit in?

u would be looken at the perfect specimen of a well bred APBT in my book!!!!
Now see i would have to disagree. To me thats too low and too wide, i was using the size weight as a comparison kinda thing.. Maybe i shoulda put it like this 9 inches at shoulder 90 pounds solid muscle and 3 feet wide and anchors 400lb pigs by hisself. Big dog or small dog?
