Your friend asks to bring his or her dog to a party. How can you set boundaries for the dog without offending your friend?
If possible, set the boundaries before the friend arrives with the dog.
Ask your friend to keep the dog on a leash at all times.
Take the blame off the animal, and put it on your space or young children by saying, “My yard is not secured for dogs, and they could potentially escape.” Or “I would hate for a child to act inappropriately to your dog and pull his or her ears or something.”
Recommend that your friend bring toys and treats to keep the dog from being tempted by other things at the party.
If the animal needs reprimanding, pull your friend aside and ask him or her to correct the behavior, rather than commanding the dog yourself.
