How do I know what size costume to buy for my dog?

Always measure your dog's chest circumference at the widest part, their neck, and their length from collar to base of tail. Do not rely on weight alone, as breeds have very different body shapes.

What should I do if my pet hates wearing costumes?

Do not force them. If they freeze, tuck their tail, or try to rub the costume off, switch to a simple, comfortable holiday bandana or a decorated collar that feels just like their everyday gear.

Are there safe costumes for cats?

Cats are generally more sensitive to clothing than dogs. Lightweight capes that attach to a harness or simple breakaway collar accessories are the safest and least stressful options for cats.

How to put it together

1
Measure your pet's chest girth, neck circumference, and length from neck to tail before purchasing any costume.
2
Introduce the costume slowly, letting your pet sniff the fabric and rewarding them with treats for positive association.
3
Gently slip your pet's front paws through the leg holes of a step-in costume, ensuring there is no restriction of movement.
4
Secure any hook-and-loop fasteners around the chest, leaving enough room to easily fit two fingers underneath.
5
Place the headpiece gently over their ears, adjusting the soft chin strap so it is secure but not tight.
6
Observe your pet's body language; if they freeze, shake, or show signs of stress, remove the costume immediately.
7
Snap your photos quickly while rewarding your pet with high-value treats, then remove any restrictive elements.

couples: Match your pet by dressing as a chef while your dog wears a hot dog costume, or go as Dorothy with your dog as Toto.
group: Dress the whole family as characters from Scooby-Doo, with your dog playing the starring role of Scooby.
kids: Pair your child as a superhero with your family dog dressed as their trusty sidekick with a matching cape.

Tips

Never leave a costumed pet unattended, as straps can get caught or fabric can be chewed and swallowed.
Avoid costumes with small, dangling parts, beads, or buttons that your pet could easily chew off and choke on.
Ensure the costume does not block your pet's vision, hearing, ability to pant, bark, meow, or use the bathroom.
If your pet hates wearing clothes, opt for a simple festive collar, a decorated harness, or a lightweight bandana instead.
