AITA for wanting my brother‘s pets gone?

(sorry for my grammar)This is a throwaway, but this all started years before today’s event. So it all started a few years ago when his ex ex-girlfriend and him got a dog together in which, after they dropped that dog, which is under her name, they broke up, and my brother decided to keep the dog. As far as I know, she hasn’t contacted him to retrieve the dog back so we’ve been stuck with that dog. My thoughts on the dog is that I don’t like him was not because he smells or anything none of that noises because he attacked me when he first arrived and caused me to go to the hospital for the wounds on around my ankle, which now I have internal scars, I think since then they’re very faint, but they’re still there so that’s the reason I don’t really like the dog. As of recent his most recent ex-girlfriend and him broke up, but she leaves her dog at our house and left my brother with her cat while she doesn’t have to deal with them or pay for them, and I was just notified that they broke up. So I told my brother when is she gonna get the animals back and he said “I don’t know I’ll probably just keep them.” and not only am I pissed about that, but I’m annoyed at this happening again because I do not want to deal with more animals in this house because we already have been taken care of a stray cat that I take it as my own. And these dogs, including this cat has damaged the house more the dogs than the cat for a while which now things I’ve been renovated so those marks ain’t there anymore, but they were there before. So both of the dogs have not only damaged the floor in multiple places, but I have damaged the the railings, the chairs anything that had wood that was ground level. Which the ex ex-girlfriend‘s dog has learned not to do but the ex-girlfriend‘s dog hasn’t fully learned and the cat itself not really that much of damages. It’s just a peas anywhere it can find where to pee like as a reason it peed on my mother‘s rug, which is downstairs now because it smells like pee, but it made her room smell like pee. These animals I don’t like in general because guess who’s stuck taking care of them when my brother leaves without the pets me and I’m sick and tired of it. I don’t wanna take care of animals that are even my own that aren’t even his, so am I the asshole for not liking these dogs and cat?

PS I do love cats, but this one has fought with my cat and taking some of his hair out thankfully that hair was just because his fur was thick for the winter as my cat is a stray and still goes outside. The dogs on the other hand I do not like doesn’t mean I don’t like dogs in general. I don’t like these dogs. Also, none of my family look at Reddit post or anything of the sort.
