We have 2 Bull terriers and a Pitbull.... They are in the house with our KITTIES and only had a problem 2x's and it was with the Male Bull terrier... the other 2 are female. He bites.. I mean he has a strong sense of character. He once bit a Homeless Person who tried to approach us on a walk in the park, and Bit a friend of my boyfriend...(who kinda looks like he could be homeless). Other than that he is a LOVER> I think its all in the person raising the dog, Don't let the pup chew on you and think its OK... Trust me Its not nice when their bigg full grown dogs wanting to Knaw off your arm. I think Pit bull and Bull terriers are very LOYAL, so treat them right and you'll have a Happy dog who will PROTECT!!!!
(yeah, i'm high).....
