Host a spooktacular party for pets and their humans by throwing a "Howl-o-ween" bash. Invite guests and their pets to dress in their favorite Halloween costumes. You can give out prizes for best overall costume, scariest or cutest outfit, and best human and pet pair.
At your event venue, set up trick-or-treating stations, with treats for the pets and pumpkin bread, caramel apples and candy corn for the humans. You also could set up a photo booth so that your decked-out "fur-togenic" pets and their human companions can have their "paw-traits" taken. Be sure to send guests home with doggie bags full of "Howl-o-ween" treats.
