Too many pets in cramped apartment. What would you do?

[Aisha Duff]

My rental has 3 roommates. The one who has been living there for 5 years already has 2 dogs. The 2nd tenant begged to have a dog as she is registering it to be a service dog (I hesitantly agreed ok. Now the potential roommate is now saying he has a service dog. That is a total of 4 dogs and 3 people in a cramped 3 bed/1bath. Can I deny his application because of the animal capacity being too high?
