Halloween Safety Tips for Chicago Pets

Halloween is such a fun, festive time with costumes, treats, and spooky décor, but it also brings hidden dangers for our pets. At West Loop Veterinary Care, we want every pet in Chicago to celebrate safely. Below, we’ll break down the common Halloween hazards for dogs, cats, and small animals, and share tips for keeping your furry friends safe.

Common Halloween Dangers for Pets

Candy and Chocolate

Chocolate contains theobromine and caffeine, which are toxic to dogs and cats. Dark chocolate and baking chocolate are the most dangerous.
Xylitol (a sugar substitute found in sugar-free gum, candy, peanut butter, and more) can cause a rapid drop in blood sugar and liver failure in dogs.
Even plain sugar or wrappers can cause stomach upset or choking risks.

Glow Sticks and Glow Jewelry

Many glow sticks use irritating chemicals that can cause drooling, oral irritation, vomiting, or mild burns if a pet chews or punctures them.

Pumpkins, Gourds, and Decorative Plants

Pumpkin flesh and seeds are generally safe in small amounts, but moldy pumpkins or decorative gourds with pesticide residue can be harmful.
Plants like ivy, autumn crocus, and black nightshade—sometimes used in seasonal décor—are toxic to pets.

Candles, Jack-o’-Lanterns, and Open Flames

Curious pets may knock over candles, leading to burns or fires. Traditional jack-o’-lanterns can also burn whiskers or paws if pets get too close.

Wires, Cords, and Lights

Chewing on decorations or cords can lead to electrical shock or mouth injuries. Keep these out of reach or secured.

Costumes, Accessories, and Masks

Costumes with small parts or elastic bands can be choking hazards. Some pets may also become stressed or overheated in costumes.

Door Traffic and Escapes

Halloween brings lots of visitors and noise, which increases the chance that a pet might dart out when the door opens.

How to Keep Pets Safe This Halloween

1. Keep Candy Out of Reach

Store all candy (especially chocolate and sugar-free items) in sealed containers and away from pets. Immediately discard wrappers and packaging. Remind guests not to feed your pet any treats meant for humans.

2. Use Pet-Safe Décor

Opt for battery-operated candles instead of open flames. Place cords and decorations out of reach and select non-toxic plants and décor.

3. Costume Smartly

If you dress your pet, choose a costume that fits well, doesn’t restrict movement or breathing, and has no dangling parts. Always supervise your pet in costume.

4. Create a Safe Space

During trick-or-treat hours, keep pets in a quiet room away from the front door. Use white noise or soothing music to help them relax.

5. Microchip and ID Tags

Make sure your pet’s ID tags and microchip information are up to date in case of an accidental escape.

6. Monitor for Signs of Trouble

If your pet is vomiting, drooling, having diarrhea, or acting lethargic, contact your veterinarian or an emergency clinic immediately.

What to Do If You Suspect Poisoning or Burn

Do not induce vomiting unless instructed by a vet or poison control.
Collect the wrapper, plant sample, or item that was ingested (if safe).
Contact us or the ASPCA Animal Poison Control Center at (888) 426-4435 right away.
