<human>: I live in an apartment with three other people. For clarity's sake, my male roommate is Paul, the dog is Jenna, Jenna's owner is Cathy, and our other roommate is Megan.

The four of us are friends from college and we moved in in December. Before moving in, Cathy told us that she planned to adopt a dog. We were all fine with this and Jenna came home the week after move-in. 

Now, I have always had a slight allergy to shedding dogs but, as long as I don't touch her (or wash my hands immediately) I am fine. 

This isn't the case with Paul. Being around her, and her dander and hair, cause him to break out in hives every day. He's pretty much uncomfortable all the time because the dog, even with proper grooming, sheds constantly. He had no history of dog allergies before so this came as a shock to him.

Cathy has been sympathetic, but she's also depressed and the dog seems to function as a therapy dog. I don't know if she'd be okay without her.

I guess I'm wondering what is reasonable to ask of Cathy. It feels cruel to suggest that she keep Jenna only in her room, but I also think Paul's comfort should come first. I also feel like, since it is her dog, she should take more responsibility for cleaning up the dog hair. On the other hand, I don't want to build more resentment among roommates and I'm totally okay with doing an equal cleaning share.

What do you guys suggest? What would you do in this situation?

<bot>: My roommate and I are allergic to our other roommate's dog. What are reasonable expectations to have of her in the hopes of mitigating our allergies?
