Help! My puppy is growing up with a bad dog.

I adopted a golden retriever and she is now 14 weeks old. Unfortunately, I live with a roommate and her dog has no training. I’ve done my best to keep my puppy apart from her dog, to the point where I’m rarely in the shared spaces (yes, this sucks but I’m terrified of her turning out like my roommates dog, she is getting enough socialization elsewhere). When I do allow my puppy to play with her dog, she starts to wrinkle her nose and get slightly ‘aggressive’, as in growling and lunging. I’ve had puppies before and this is not normal behavior. It only occurs after she’s been playing for a few minutes. I don’t know if it’s because this dog plays so rough that it’s unintentionally hurting her or that it’s a dominance thing. I would just like some advice on how to handle this situation.

I am working to avoid all other bad behaviors that might be instilled in my puppy, but I’m not sure how to handle this one. She doesn’t do this with other dogs, just my roommates.

Is the only solution to not let her play with my roommate’s dog?
