I adopted a male pit/lab mix from the local shelter around 2.5 years ago. He's never been aggressive towards people, but my girlfriend has a male bernese mountain dog mix that he seems to randomly attack. They got along well for the first year after her dog moved in. I have noticed some patterns over the past 8 months that it's been happening though.
It never happens when I'm alone with them or if nobody is home. It only happens if my girlfriend is here, or if she is alone with them.
We also have a 30 lbs paralyzed female pit mix, and another female dog that he doesn't attack.
He does seem to attack if toys are out and the male comes close. Again, doesn't attack the females. The paralyzed dog can take the toys right out of his mouth, and he doesn't care. (seems like an obvious common problem)
He seems to have "nervous days" where he will pee a little when my girlfriend baby talks him, then he shakes anxiously after the pee. Those days seem to be when he will attack. Other days they are fine together.
The attacks aren't terrible, as the other male dog wants nothing to do with a fight, and just relents. He gets some cuts on his face, but no major injuries have happened. He hasn't caused any injury since being put on the dog version of prozac. He was actually doing really well for the 2 months he's been on it, but now he's snapping at the other dog. I can't tell if he just has bad days and needs to be separated during those days or what's going on. He's had the "bad" days for the past 4 days, which hadn't happened before.
Sorry for the long post. I'm always nervous to leave the house. Thanks for any help or ideas.
