Ok, Tashia is 8 weeks old and I had my buddy bring over his puppy. (mutt) Its cute and a male. Its about 14 weeks old and 10 pounds heavier, Tashia beat the smack out of him he was yelping and freaking out. I had to separate them and make him take the poor chap home. I felt bad, I dont want her to be like that with other dogs. Is this normal for a pit? I know the steriotypes, but want her to be better....differant. Any advise? Please help. Did I make a mistake in my choice of pups?
