Keep them happy. "Before having pets join in the Halloween fun, it's important to assess whether your pet will be comfortable participating, or if the festivities will cause undue stress," says Dr. Simon Starkey, Pet Care Expert at PetSmart. "If you have a young or senior pet, or one that is shy around others, it's better to give them a quiet space away from all the activity where they'll feel more comfortable."

Make sure treats are pet friendly. With so many Halloween treats about the home, you want to make sure your dog doesn't accidentally consume something that could be harmful. Chocolate is particularly tempting for pets, but it can also make them seriously ill. Instead, choose a pet friendly treat to celebrate, such as GREENIES Dental Chews, which also keep pets' teeth clean and their breath scare-free.

Keep them safe. If you plan to take your dog around the neighborhood in the evening, make sure they're properly outfitted. Reflective leashes, collars and ID tags with flashing lights are essential accessories for any pet Halloween costume.

Halloween Pet Fun
"Choosing a costume for your pet is like choosing a costume for yourself - you want something that reflects your or your pet's personality," says author and entertainment expert Kimberly Schlegel Whitman. Here are a few favorites exclusively available at PetSmart:

Make your pet a star. If you fancy your pet a rock star, consider dressing them for the part. Check out the Bret Michaels Pets Rock wig. With blonde tresses and a bandana to top it off, your pet will be ready to rock and roll.

Classic costumes are spooktacular. For a fantastic costume that also offers safety features, check out the glow-in-the-dark Martha Stewart Pets Black Halloween Skeleton costume. Or, if you love retro, outfit your pet in the Top Paw Plush Sock Monkey costume, which is sure to evoke some "oohs" and "aahs" from witches, goblins, zombies and monsters of all ages.
