What size costume does a French Bulldog wear?

Most French Bulldogs require a size Medium or Large in standard dog clothes due to their exceptionally wide chests, even though they are short in length. Always measure the chest girth rather than relying on weight guidelines.

How do I know if my Frenchie is stressed in a costume?

Signs of stress include freezing in place, pinning their ears back, whites of the eyes showing (whale eye), licking their lips, heavy panting, or trying to scratch the costume off. If you see these signs, remove the outfit immediately.

What are the safest costumes for French Bulldogs?

The safest options are lightweight capes, simple neck bandanas, or step-in front-facing costumes (like a delivery driver) that leave their head, ears, and breathing passages completely unobstructed.

How to put it together

1
Measure your French Bulldog's neck circumference, chest girth (the widest part behind the front legs), and back length.
2
Select a costume designed specifically for stocky breeds, prioritizing open-face designs that do not cover the snout or restrict breathing.
3
Introduce the costume slowly, letting your dog sniff the fabric and rewarding them with treats.
4
Gently drape the costume over your dog's back, securing the chest straps first, ensuring you can easily fit two fingers under the straps.
5
Fasten the neck straps loosely, making sure there is absolutely no pressure on the windpipe.
6
If using a headpiece, gently pull their ears through the designated slots and secure the chin strap loosely.
7
Let your dog walk around indoors for a few minutes to ensure they have a full range of motion and are not showing signs of stress.

Avoid any costumes with small, dangling parts, buttons, or sequins that your dog could chew off and swallow.
