Dog Halloween Costume Safety: Fit, Materials & Getting Your Dog Used to It

A good Halloween costume is one your dog barely notices. That comes down to four things: the right size, a clear face, safe materials and a little practice before the big night.

1. Get the size right

Measure the widest part of the chest, just behind the front legs, and add about 2 inches (5 cm) for movement. Compare it with the size chart on the product page – every costume in our Halloween shop lists its own measurements. If your dog is between sizes, size up: costumes go over the fur and are worn for short periods. Our size guide has a calculator.

2. Keep the eyes, nose, mouth and ears free

Skip masks, hoods that drop over the eyes and anything that wraps the muzzle. Your dog needs to see, pant, drink and hear normally – especially with doorbells, kids and strangers in costumes around. Hats should sit behind the ears and fasten under the chin with a soft, breakaway strap.

3. Choose safe materials

• Soft, breathable fabric with no rough seams at the armpits
• No small buttons, bells, sequins or pom-poms that can be chewed off and swallowed
• Velcro or snaps rather than tight elastic around the neck or legs
• Nothing that drags on the ground or tangles the legs

4. Help your dog get used to it

1. A week before Halloween, lay the costume on the floor and reward your dog for sniffing it.
2. Put it on for 30 seconds with treats, then take it off. Repeat over a few days, a little longer each time.
3. Watch the body language: a tucked tail, freezing, licking lips or trying to back out of it mean it is too much – try a simpler outfit like a themed hoodie or t-shirt instead.

5. On the night

Never leave your dog alone in a costume, take it off before naps, keep them away from candles and jack-o'-lanterns, and keep the candy bowl out of reach – chocolate and xylitol are toxic to dogs.
