Am I bad for hating the dog

I absolutely love my S/O but I absolutely despise his dog. It's never been worked with and never will be, because he doesn't want the dog to change. My parents have three dogs, and all of them are relatively well behaved, and they aren't aggressive towards animals nor are they typically that way with people. When I want to go out with him, for the evening we wouldn't be able to, because nobody at his house will take care of the dog, I can't have guests over because the dog misbehave and humps everyone. The dog will get up seven times a night after bed time to whine at the door to be let out, so I can never get any sleep. The dog will also roll in fecal matter and my boyfriend doesn't care. My friend absolutely loves having us over for weekends, but he always declines and I go over by myself because he has to watch the dog and the dog can't come with us because she has animals herself. He refuses to crate the dog for those times we go out. It just upsets me.
