Should I give up my dog after he bit my boyfriend over discipline?

My dog bit my boyfriend after he disciplined him for pooping in the house. And when I mean disciplining, he put his head into the poop and lightly spanked him and told him no. The bite wasn’t too bad only because my boyfriend stopped his mouth before going any deeper and drawing blood. My boyfriend got really upset and basically gave me an ultimatum “it’s me or the dog” because he’s afraid that my dog will kill his cat and his cat is very important to him. He just doesn’t want to risk his cat dying. He doesn’t think we could ever live together if my dog is in the picture. And he thinks my dog is a danger now that he has bit someone. For the record, my dog is the sweetest most gentle dog there is, and typically is a scaredy cat, and I assume he has been abused in his past. He has never even come close to showing aggression to anyone. What are your thoughts on this? Would you give your dog up for a future with someone?
