We have a family member who wants to bring their dog to the wedding. They always travel with it as an "emotional support animal" and feel very strongly that the dog is included everywhere that they go and are very belligerent if questioned. They have not approached us as (others have told us) they are "assuming the dog is invited." There are a few guests who are very anti-dog out of fear and allergies (we are not anti-dog, but we just don't want a canine wedding guest.)
The dog is not invited. The dog won't be allowed in the restaurant where we are having our reception. How do I politely mention this if the individual does not ask?
