Pets in costumes can look silly but they often make adorable pictures! If you're planning on dressing your pet up, or you have in the past, join the PetSugar Halloween Costume Extravaganza group on Team. Start uploading your pet's Halloween costume photos to share with us now! I'll look through our submissions, and pick a winner next week. One lucky winner can either choose a PetSugar tee for herself or one for her pup!

Want your own PetSugar swag? Stay tuned for more contests during the month of November. Check out some of my favorites below, but there's lots more to choose from.
