My sister in law and her family (husband and child) will be moving in to our place. Potential problem? They also have dogs. They have always been welcome when they visit, which is just a few days at at time, but now that it could be short or long term, I can't bear the thought of the dogs living with us. One of them does not get along with our dog and has snipped at her a lot. We can clearly see she is not herself around him and this is her home. How do I address this?
