That is hard for me to believe. My black Lab has never even taken a snort at anyone. He is 120 lbs and lets some of my small nieces and nephews tug at his ears. He likes the attention.
So, you're calling me a liar? Or do you believe no lab's ever bitten anyone?
My Amstaff never growled, snipped, snapped, chased, leg humped, or jumped on any person, dog, cat, squirrel, chipmunk, or baby.
I guess, using your logic, that means I should find it hard to believe any pit bull has ever bitten anyone.
