I was an ADBA judge for over 20 years and saw many over 100# registered APBT's. Most all came from Whopper-Dagger-Camelot or possibly Couteriour lines. There were questions on all these lines being purebred but it was never challenged in the DNA era. They were wt. pullin dogs. Most of the APBT's over 100# that I've seen are usually 20# or more overweight for the best results.
Exactly. The Whopper dogs have Mastiff crossed in, and there's proof of that too. Funny how that was swept under the rug if you will.
