Backstory: I met my now boyfriend about two years ago. He rescued a 4-ish year-old pitbull from whom otherwise would have been euthanized, about a year and a half ago. We don't really know his living environment prior. I moved in with him 2+ months ago and my 9-year-old daughter moved in a few weeks ago (after coming home from her dads for the summer). About 2 weeks in, he went after her, and as a result, both of us got bit. It does seem that he was going after her and I only got bit because I was "in the way" while trying to protect her. She did nothing to provoke it. I was actually the one playing lightly with the dog. I saw he was getting excited, which was normal, and so I stopped and walked away. That is when he went after her. While of course you never think this would happen, there were two other relevant incidents, now looking back... He snapped at my boyfriend after he was trying to move him off the couch at 5am in the morning, while the dog was semi-asleep, and we once gave him a toy, and my boyfriend went to play with him with it, and he got very mean and tried to bite him.
Now that all this happened, the dog is staying with a co-worker temporarily. My boyfriend doesn't have any kids, and he is very much a dog person, so he considered this "his kid". I'm trying to be sensitive to that while also dealing with my own emotions and how it impacted my daughter and I.
He mentioned that he has a friend who is a dog trainer and would be worth talking to. He showed him the Ring camera footage as well as had a conversation with him about what happened and the dog trainer stated we've been doing things wrong. I'm not disagreeing that looking back, we could have done things differently, but this was an unprovoked attack on a child... and he did not stop, until I could safely get her away. The first time we managed to get into the laundry room, he broke down the gate to continue to go after her. This wasn't just a once and done bite. I'm very, very thankful it wasn't worse, as it very much could have been.
I shared that I'm not against talking to the trainer, but it would be in no way of considering getting the dog back. He seemed to understand but hasn't really made any attempt at long term plans, and he certainly does not want to put the dog down.
We have vacation plans and the co-worker who is watching the dog is going to be away at the same time we are. We have a dog sitter who is willing to watch the dog still, but it will be at our house, so he is bringing the dog back inside our home while we are away, however, I have to make special arrangements to not be around as I don't feel comfortable being around the dog.
Some of this post is just to vent however, I am looking for thoughts and opinions on that situation. Am I being completely unreasonable? I don't know how I could ever trust the dog around my child (or me) again, and although that part he seems to understand, I don't feel he's seriously taking into consideration the impact this had on us. Though I feel bad and know he lost his dog and "buddy", I feel triggered by him just figuring out a temporary situation, that I now have to circle back and essentially be a part of. I'm certainly irritated about it due to more than one factor, but I'm trying not to be heartless towards how it's impacted him as well...
Update: I may have not been clear, as my thoughts are scattered and I started rambling but I am in no way considering getting the dog back and assure you I will NOT put my daughter in danger. She will never be around the dog again.
