How much breeding was required to "breed in" the fighting instinct? And fighting what/whom? Dogs? Humans? Is 90 years enough to breed it out?
And please provide your educational/professional qualifications, because frankly you sound like any other internet expert/blowhard.
Thousands of Staffs go into the AKC show rings every year with wagging tails and never so much as growl.
AmStaffs and Staffordshire Terriers are the original ‘pit bull’ stock.
They’ve been doing so for a hundred years.
I have, however, never seen a handler who was wearing a backwards hat, droopy ass pants or a hoodie.
Probably just coincidence, that.
[the original purpose of those breeds was to assist cattle drovers, hence the “bull and terrier” old name. the dog was created to grab and tenaciously hold the nose of dangerous bulls to protect the drover]
