I need advice I guess.

I’m pregnant, and my mother in law and her husband smoke in their house like crazy. As soon as you walk in it’s all you smell. It’s always dark, dusty, and I feel like theres almost always smoke floating around somewhere. The furniture reeks of smoke. They also have a very big dog who they have not trained. He has jumped on me when I walk through the door and hes knocked me down the steps and on the floor several times (not while pregnant). He doesn’t calm down even after hours of being there. My husband and I decided we don’t want to be over there anymore bc of the dog, the second/third hand smoke. And don’t want our baby around any of that when born. We know for a fact it’s going to cause issues with them bc we don’t really get along with them as is. I just want what’s best for my baby, and my body right now. Is that wrong of me? I’m so anxious for the moment this conversation is going to happen. Any advice? Please no negative comments. I know a lot of women smoke while pregnant, but my personal choice is to not smoke. I’m not bashing any woman who does. I’m just sad it’s got to the point I have to care so much about what they say and think just bc I’m putting my child (whether born/unborn) first.
