am I wrong? boyfriend /dog vs me

So I usually wouldn’t ever post such things on here, but i’m at a complete loss. this may not even get any response to, but I thought I would give it a shot.

my boyfriend and I have been together for a year and a half. we have our own house, have lived together since July of last year.

I already had two dogs when we got together and i lived in my own place. I have had my dogs for 5 and 3 years. (since they were puppies)

He gets this dog, a Mastiff (180 pound dog) in August. I wasn’t cool with it because he was too big. He has to stay in the house (he doesn’t have to but my boyfriend says he does). His previous owner had to get rid of him and my boyfriend offered to take him. So here we are with this big ass dog IN the house. He gets on the furniture. Broke our couch. We have to put the coffee table on the couch any time we leave because he still tried to get on it.

he slobbers all over everything.

he cannot be disciplined because he will try to bite you.

he doesn’t listen.

I let him outside and he scratches on the door so loud/hard/heavy that the door if literally coming off the hinges/frame. my boyfriend acts like it’s no big deal.

I work nights (12-hour shifts) therefore I sleep during the day. there are days I might get two hours of sleep because of the dog. I put him inside, he whines wanting outside. I put him outside, he whines and scratches and barks wanting inside. I turn my fan on high, the door is shut, and sometimes the AC is on and I can still hear him outside.

*** the dog is just over three years old ***

so here’s where i’m asking if i’m wrong — my boyfriend works out of town two weeks at a time and is home for only two days on the weekend at the end of that two weeks. I don’t want the dog. he can’t take the dog with him. I want to get rid of him. I cannot handle having a dog that doesn’t listen and tries to bite and tear the door down anytime he gets in trouble or sent outside. My boyfriend tries to guilt trip me anytime I talk about it. He’s all on board but then he waits a little while and gets pissed off.

AM I WRONG FOR WANTING TO GET RID OF A DOC THAT I HAVE NO CONTROL OVER ?! ESPECIALLY since it’s my boyfriends dog and he’s NEVER home.

(I tried to post a video of what the dog does but it won’t let me post it)

.

EDIT TO ADD: when he got the dog, he was home every night, but he’s no longer home every night. (as posted above, he’s only home two days out of every fourteen). Also, I was kind of put in the middle / on the spot when the dog arrived at our house “do you want it Ash?” and the owner basically had no other option but to leave it because my bf wanted him and I DID NOT. I don’t have the time and energy to give to a dog like him. His size and the attention he needs is way way way too much for me.
