Agressive to Male dogs bigger than himself. Okay with small dogs/any female dogs. Currently lives with a 5 year old child, good with kids. We recently moved because he would get into fights with my mothers golden retriever. We searched for months for an apartment that would even accept a pitbull. Now that we have moved we have noticed he is more aggressive towards our guests. He will bark at them at fist and warm up to them in a few minutes, but he will bark and lunge at anyone who walks by me while i walk him. We are sad to give him up but we also do not have the means to help his behavior. I am expecting and not sure how he will behave. HE IS A VERY SWEET DOG TO WHO HE KNOWS AND HE DOES WARM UP. Completely house broken. His best fit would be with someone with no animal or someone with a female dog. Also someone who has a large private space to walk him in, OR someone who is willing to train.
