What do I do?!!!

I been in a relationship with my boyfriend for 2 years now. We have a place together. We had one place together and back then he couldn’t bring his dog due to the apartment we lived at only would take one dog as an emotional support animal. So I had my little doggie. So back in July of last year it came to an emergency and he had to take his dog. My lease was coming to an end then so it didn’t quite matter. Okay so we moved into a new place after that. I’m working, and handling all bills etc. The only way we could have two pets here is an emotional support letter. I had one to cover my dog because she’s been with me forever so I had to get a second one to cover his dog stating the dog is mine so he could be here. Well his dog is a bigger dog and excessively sheds big time! Lately I believe that I have a huge allergic reaction to his dogs fur! It’s everywhere even when vacuum everything I can’t get it all. I itch like crazy and it drives me nuts. He tries to keep the dog off the couch when I’m around but when I get home in the morning from work the dog is on the couch with all this fur everywhere ! I paid 2,000 for my new couch set and it’s basically getting ruined. My bed sheets have hair everywhere even when the dog jumps up on the bed and he tells him to get down he leaves hair. My bf doesn’t seem to care that the dog fur is causing an allergic reaction and he doesn’t seem to listen.! I politely told him that the dog doesn’t necessarily need to be on the couch. Even with a sheet. I’m paying for everything here but I’m so sick of being filled with dog fur! It’s in my purse ! Hell sometimes it’s on my pots and pans! I can’t even sit anywhere without having hair on me ! I know it’s not the dog fault but my bf doesn’t seem to care! My bf is on my lease and doesn’t work! It’s me paying everything here and basically cleaning everything! I have a dog as well. She’s a chihuahua. Barely even sheds fur and is in the crate of when it’s bed time. I’m just sooooooo annoyed of all this freaking hair and itching is driving me nuts that he doesn’t even care! Sorry for sounding so ticked off!
