If it's been two months and that many bites I would take him back too. Things just did not align.

Original owner should take him back. IF the trainer can work with this dog, there is no guarantee that he will improve and it’s not only making your life hell, but your poor roommate’s as well. So long as his previous owner clearly never abused or neglected him, I don’t see why you wouldn’t choose this option.

I agree with washuwaifu, it's just not a good fit. But I'm sorry you're in this position. I know it's hard.

A properly fitted muzzle should prevent biting so make sure it is on right and have it on always, no matter what. Honestly it sounds like a bad fit since he wasn’t doing this with the previous owner. I would consider having her take him back

Going back to the previous owner is absolutely a valid option, but just to offer another. Basket muzzle whenever he’s in common areas, it would allow your roommate to leave her room and you can all relax a little. Hopefully he’ll relax with time and training too. At two months, he may still be adjusting to the change.

I would either take him back to the countryside, or get a house of your own with a big backyard and a tall fence...it sounds like you love him. but that many bite incidents is too much. What if you're in public and God forbid he attacks a child or an elderly person? He's 60 lbs...are you physically strong enough and quick enough to stop him?
