Dog urine around baby.

My MILs house has 6 dogs. It's a very small house so it's even crowded without them there. They pee on the kitchen floor daily. As well as the living room carpet. She says she bleaches her kitchen floor daily but the carpet has not been cleaned. Even though she cleans the floors, I don't feel comfortable with our baby there because it could be dangerous for her to breathe that in. Am I wrong to deny her going over there? (Shes not born yet but will be this week) 
She's mad because we are not allowing anyone at the hospital, she's unable to come to our house because shes very allergic to cats and we have 6 of them. And it's winter so there's no other way for her to see the baby. She's trying to guilt us and saying its my fault and i dont want her around the baby when I just dont want her around that. Plus the dogs run around, bark ALL the time, have no training, and jump.
