Halloween 2026 pet costumes: DIY ideas and vet-backed safety rules

Top pet costumes in 2026

Other 2025 favorites were bumblebee (4%) and superhero (3.1%). In 2025, 23% of celebrants said they planned to dress up their pets.

DIY directions

Keep it simple. A loose vest, bandana or collar piece is usually easier for a pet than a full suit.

• Pumpkin: an orange fleece or felt vest with a few vertical lines drawn on, and a small green felt “stem” attached to the collar.
• Hot dog: a tan felt tube that wraps the back like a blanket, with a red or brown felt “sausage” stitched on top and a wavy yellow stripe for mustard.
• Ghost: a white bandana with two felt eyes. Avoid a full sheet over the head.
• Bumblebee: yellow vest with black felt stripes, and soft antennae on a headband only if your pet tolerates it.
• Superhero: a short cape tied loosely at the neck with a fabric emblem. Keep it well clear of the legs.

Then photograph it: the Social Media Image Maker has a Pinterest size (1000×1500) for a costume reveal post.

Costume fit rules

The American Veterinary Medical Association (AVMA) says a pet costume should:

• Fit properly and be comfortable.
• Have no pieces that can easily be chewed off or cause choking.
• Not block your pet’s sight, hearing, breathing, mouth or movement.
• Be tried on before Halloween so your pet gets used to it.
• Never be worn while your pet is unsupervised.

If your pet seems distressed, skip the costume. A festive bandana is enough.

Candy and food dangers

• Chocolate is toxic to dogs. The FDA says darker chocolate is more dangerous: about 57 mg of theobromine per ounce in milk chocolate versus about 364 mg in baking chocolate.
• Xylitol, a sweetener in some candy and gum, is also dangerous to pets (AVMA).
• Raisins can cause kidney failure in dogs (AVMA).
• Do not feed pets Halloween treats. AVMA notes you often cannot tell what a candy contains just by looking at it.
• If your dog eats chocolate, the FDA says to call your veterinarian or an animal poison control center.

Trick-or-treat night

• If your pet is wary of strangers or may bite, put it in a room away from the front door during trick-or-treating, or give it a safe hiding place (AVMA).
• Make sure ID is current (microchip, collar and ID tag) in case your pet escapes through the open door (AVMA).
• Keep your pet indoors (AVMA).
• Place jack-o’-lanterns and candles where pets cannot knock them over.
• Keep glow sticks, batteries and human costume pieces away from pets. Chewed glow sticks taste bad and can cause heavy drooling, though they are not likely to be harmful (AVMA).
