Yes, but ... The school should check the dormitory regularly every week, and keeping pets will definitely be reported. And if you have time to take care of it, because dogs are different from people. He needs to eat, drink and urinate regularly at every meal. And dogs may not adapt to the new environment. So there are also cases of screaming. It may disturb the dormitory next door. The dog needs walking. Otherwise, he will be depressed alone, and you can only accompany him when you go back to the dormitory after class. Dogs stay in cages all day. How lonely they are. Shovel shit for him. The dormitory smells like a dog. If your roommate doesn't mind, and you have the ability and time to have a dog, that's fine.
