Alexsandra,
There are limited slip collars, they tighten but only so much so a dog can’t actually choke themselves. Look at yellowsnowdoggear and Lupine.

Laws are different everywhere. Here, off leash is fine as long as the dog is under your control. Your roommate is nuts to think the dog would always listen to him. Not long ago, I read where a trainer had the stupid thought to let their beagle off leash. Dog saw something ran across the street, died when hit by car. I can’t chance it.
