We have a pitbull who is very well behaved. Great dog. He was trained but he is very attached to me. My fiancé and I got into an argument and he started yelling. My dog (osiris) went after him. He didn't try and bite him but he keeps barking. He stops when I tell him to. He actually comes and sits with me. I even put his harness on. But he won't stop even now we are fine. He has never did this before. Oh yeah I'm also 8 weeks pregnant and he keeps standing in front of me like he is protecting me.
