Dog Clothes Size Chart
XS through 3XL — back length, chest girth, and weight, and how to measure all three before the fit drops.
Apparel Sizes XS–3XL
Fit guidance below is Supreme Paw Supply’s general standard — sizing varies piece to piece, so always check the size chart on the product page before ordering.
| Size | Weight | Back length | Chest girth |
|---|---|---|---|
| XS | 2–8 lb | 8–10″ | 13–16″ |
| S | 8–15 lb | 10–12″ | 16–19″ |
| M | 15–30 lb | 12–16″ | 19–23″ |
| L | 30–55 lb | 16–20″ | 23–28″ |
| XL | 55–75 lb | 20–24″ | 28–33″ |
| 2XL | 75–100 lb | 24–28″ | 33–38″ |
| 3XL | 100+ lb | 28–34″ | 38–46″ |
When the three columns disagree, chest girth wins — a hoodie that clears the chest can run slightly long, but one that binds the chest never gets worn twice. Between sizes on chest, go up.
How to Measure Your Dog for Clothes
- Back length: base of the neck (where a collar sits) straight along the spine to the base of the tail, standing square.
- Chest girth: around the widest part of the ribcage, behind the front legs — the make-or-break number for hoodies and jackets.
- Weight: the shortlist number. Weigh yourself holding your dog, subtract yourself, done.

Fit Notes by Build
Breeds wear clothes differently. Barrel-chested builds — Frenchies, Pugs, Pit Bulls — often need a size up on chest even when back length says otherwise. Long, low dogs like Dachshunds fit chest-first with extra length to spare. Deep narrow chests (sighthounds) can size down for drape. Browse dog hoodies and hypebeast dog clothes for small-to-medium fits, and big dog clothes cut for the XL-and-up crew — every product page carries its own chart for the final check.
Frequently Asked Questions
How do I measure my dog for clothes?
Three numbers: back length from collar-point to tail-base, chest girth at the widest point behind the front legs, and weight. Chest girth is the decisive one for fit; back length determines how the piece drapes.
What if my dog is between sizes?
Size up — always on chest girth. Dog clothes tolerate a little extra room far better than a tight chest, which restricts movement and ends up in the back of the closet. For barrel-chested breeds, between-sizes almost always means the bigger size.
Do dogs actually need clothes?
Short-coated, small, senior, and lean breeds genuinely benefit in cold or wet weather — a fitted layer holds body heat they can’t. For thick-coated breeds it’s less necessity, more statement. Either way, fit is what makes it work: a well-sized piece doesn’t alter how a dog moves.
