My brother kicks my dog when he comes over to see our Dad. Any advice?

My dad with dementia lives with me. He's been living in my home for just a month now, we've got a good routine set and I've hired a nurse to occasionally come in and help. I live about an hour away from my brother, we do not get a long, he is hostile towards me, and he has a record for assault (not against me). I have DPOA for dad, I nice home, accustomed to taking care of other people. Brother is 50 never married, no kids, does not work, desperate for money. We are opposites in every way. I've handled everything well with him, threats, smart remarks, playing games, you name it, but twice now that he's come out to see dad, he kicks my dog when he walks by her, she's a large dog, about 65 lbs, she'll yelp, get up and walk off and then growl at him, he lays into her on purpose, she doesn't even have a chance to get out of his way. I've told him to not do it, but because he knows it bothers me and it's not right, he does it. I don't trust him obviously, so I don't want to put her in a separate room when he's here because I do feel threatened by him. What can I do? I feel if I tell him he's not allowed here, it's just fuel for more grief he wants to cause me and I have quite enough as it is. Since his actions are so predictable, I've considered simply record the video of him doing this "next time" on my phone and taking it to the police and pressing animal abuse charges against him. What do you think?
