i have heard of puppy farewell parties! people do this when their dog has puppies and it comes time to give them away to new homes. the owner of the mother usually gives the puppies to their new owner with a gift bag filled with treats, toys a collar/leash set and sometimes they include bandanas. I have never been to one of these though but I have seen them on T.V and my grandma went to one when her friend was picking up the puppy they chose to take home! My grandma says they're kind of neat and fun!
