Trick or (doggy) treat? Enter for a chance to win an adorable Animal Planet costume for your pup just in time for Halloween. One winner will be selected per day through Oct. 21! (Read the official rules.)
Best of all, a portion of proceeds from the sale of the Animal Planet pet costumes benefits Animal Planet’s R.O.A.R. (Reach Out. Act. Respond.) program, whose non-profit partners include the Petfinder.com Foundation. So you and your dog can enjoy the Halloween treats and help homeless pets at the same time!
