My future mother in law is a very sweet women, but very socially awkward. She has some mental health issues that allows her to bring her dog with her everywhere. Side note: her dog is an emotional support dog not a certified service animal. She recently informed us that she plans to bring her dog to our wedding. This dog for one is not very well behaved and two only allows her to touch him. Our wedding venue doesn't allow animals into the venue unless the dog is certified. She is a very sensitive person so we know she isn't going to take this lightly. My FH has also expressed to me that he isn't comfortable with her dog being at our wedding. How do we approach this subject? Any advice?
