I bought a female Brindle pit for breeding and she didnt like my male and she would try to fight him all the time. He didnt really fight with her, just her with him. She wasnt able to hurt him enough to make him mad. I got rid of her after 3 months when I gave up on them being friends. He seemed sad when she left even though she was mean to him. He is happy with other dogs no matter sex or breed. He Goes pout into the front yard to hang out piss etc... The other dogs walking by always want to fight him, but he always wants to be friends. He looks so confused when they try to attack or growl.snap. This Dobie made him owner fall off his bike to get to my dog. Poncho trotted over to sniff and the dobie snapped at him. Poncho got bit and snarled and jumped at him and I think he might have bit him. The dog actually cried and ran off. I was so surprised that poncho acted like that. Took him in and he was bleeding. So I know he will fight, but only if he really feels threatened.
