In New York city, Animal Fair hosted a pet costume contest to benefit the Humane Society of New York.
The contest was decided by celebrity judges and their pets.
The event's howl-o-ween pet costume contest's winner got a doggy bag of treats and a guest appearance as a model on TV!
Attendees had a good time while raising money for one of New York's best animal shelters.
Check out a bunch of pics below from the event.
