Is it acceptable for me to find another home for my boyfriend's dog?

My boyfriend moved in with me a few months ago. I love him, but his dog is wrecking my house. Every day we get home, there is a huge mess on the floor, and several things will be ripped up (including the couch). He's slowly eating all of the doors, and there will be food and poop everywhere. Even though I come home during all of my breaks to take him out, he still poops and pees in the house every chance. I can't financially afford to have the dog wrecking my house. I've tried talking to my boyfriend about the dog to try and come up with a solution, but it never ends well. The dog is the only thing we fight about because I want him out of the house and my boyfriend doesn't want to see him go. It's not the dog fault though; I understand that. The dog is only a year old, and he isn't a bad dog. He's just too big of a dog for where he is; he should be a farm dog instead of a town dog. I don't hate the dog, but I just can't afford to continue having my house torn to pieces.
