Halloween Dog Safety: Candy, Costumes and Visitors

Halloween can be exciting for families, but unfamiliar costumes, frequent visitors, decorations and accessible candy can introduce unexpected risks for dogs.

A little preparation can help your dog enjoy a comfortable evening while everyone else celebrates.

Keep Halloween candy out of reach

Chocolate and certain sugar-free products are particularly dangerous for dogs.

Chocolate contains compounds that can be toxic to dogs. Dark chocolate and baking chocolate are especially concerning.

Some sugar-free candies and chewing gums contain xylitol, a sweetener that can cause dangerous changes in a dog’s blood sugar and potentially serious liver damage.

Before Halloween begins:

• Store all candy inside closed cabinets.
• Keep trick-or-treat bags off the floor.
• Dispose of candy wrappers securely.
• Check the ingredients of sugar-free products.
• Never offer Halloween candy to your dog.

If your dog eats chocolate or something that may contain xylitol, contact your veterinarian or an emergency veterinary clinic immediately.

You can also contact ASPCA Animal Poison Control at 888-426-4435. Consultation fees may apply.

Choose comfortable Halloween costumes

Some dogs enjoy wearing costumes. Others prefer to participate without them.

If you choose a costume, make sure it does not restrict your dog’s movement, breathing, vision or hearing.

Avoid outfits with loose buttons, ribbons or decorations that could be swallowed.

Try the costume on before Halloween and observe your dog’s behavior. If your dog repeatedly tries to remove it, freezes or shows signs of discomfort, take it off.

A simple, properly fitted bandana may be a more comfortable alternative.

Never leave your dog unattended while wearing a costume.

Prepare a quiet space for trick-or-treaters

Halloween often means repeatedly opening the front door to unfamiliar visitors.

Even dogs that normally enjoy greeting people may respond differently to costumes, loud noises or large groups of children.

Prepare a comfortable room away from the entrance.

Include your dog’s familiar bedding, fresh water and an appropriate enrichment toy.

Before visitors arrive:

• Take your dog for a walk.
• Allow time for a bathroom break.
• Prepare the quiet room.
• Close doors or install appropriate barriers.
• Remind family members not to release the dog when answering the door.

Our dog toy safety guide explains how to inspect enrichment toys before offering them to your dog.

Inspect Halloween decorations

Holiday decorations can become dangerous when curious dogs chew or swallow them.

Keep electrical cables, artificial cobwebs, ribbons and small decorative pieces out of reach.

Avoid using lit candles in places where your dog could knock them over. Battery-operated alternatives reduce the risk of fire, but batteries and small components must also remain inaccessible.

Check decorations regularly and remove anything your dog attempts to chew or swallow.

Update your dog’s identification

An open front door creates opportunities for dogs to escape.

Before Halloween, check your dog’s collar, identification tag and microchip registration.

Make sure your current telephone number is associated with the microchip.

For nighttime walks, use a secure leash and reflective equipment.

If your dog is uncomfortable around crowds, choose a quieter route and avoid the busiest trick-or-treating hours.

Offer dog-friendly Halloween treats

Your dog does not need human candy to participate in Halloween.

Try a familiar food puzzle, an appropriate commercial dog treat or a simple indoor scent game.

Maintain your dog’s normal dietary routine and avoid introducing several unfamiliar foods at once.

Our dog treat calorie guide explains how to incorporate occasional rewards into a balanced feeding routine.

Halloween preparation checklist

Before October 31:

• Store candy and wrappers securely.
• Choose a comfortable costume, if appropriate.
• Inspect decorations and electrical cords.
• Prepare a quiet room.
• Update identification and microchip information.
• Plan nighttime walks carefully.
• Save your veterinarian’s emergency contact information.

Halloween does not have to be an elaborate experience for your dog. Familiar routines, secure surroundings and a quiet place to rest can make the celebration easier for everyone.
