Is it rude of me to not want my mom to bring her dog to my house

I have a 4 month old baby and I live 40 minutes from my mom. She loves to see him and comes over once or twice/week. I go there once every week or every other.

After I told her I was pregnant last year, she decided to get a dog. Love that for her. But unfortunately I live in a studio apartment and all of my baby’s toys and stuff are on the floor bc he rolls over and you’re supposed to put their activity gym on the floor so they can’t fall off of it. Baby toys look exactly like dog toys, and her dog will grab literally anything and run away with it/try to chew it up, including adult shoes. He is also a puppy and is super hyper around my baby and tries to bite his feet when anyone is holding him (my baby) while sitting. Lastly I have chickens and ducks and the dog runs around with them, and would track dirt and poop into my house. That’s why I don’t have a dog, I don’t want to be mopping every day.

For those reasons, I don’t want her dog inside my house, ever. I’ve told her this many times. I’m nice about it and I tell her I like the dog and I play with him when I’m at her house. When she brought him to my house in the past, he stays outside. But she always asks if he can come in, says idk why he can’t come in he would be fine.

So now it’s to the point where she mentions the dog every time she comes over. I don’t want to hear about it anymore! I said no. It’s very annoying bc she is making it seem like I’m a dog hater or just a mean person to not allow her angel puppy inside (in her opinion)

Am I being unreasonable? If I’m being reasonable how can I shut these comments down once and for all?
