How to Measure Your Dog for Clothes: Complete Size Guide
Nothing ruins a cute dog sweater faster than a poor fit. Too tight, and your pup can’t move comfortably. Too loose, and they’ll trip over excess fabric. Getting accurate measurements before you buy ensures your furry friend looks great AND feels comfortable.
According to the American Kennel Club, properly fitted dog clothing should allow full range of motion without restricting breathing or movement. Let’s make sure you get it right.

The 3 Essential Measurements for Dog Clothes
1. Neck Circumference
Wrap the measuring tape around the base of your dog’s neck — right where a collar would sit. Keep it snug but not tight. You should be able to slip two fingers underneath comfortably.
Pro tip: If your dog has a thick coat, measure over the fur as it would naturally lay. The veterinary experts at PetMD recommend accounting for coat thickness when sizing winter wear.
2. Chest Girth (Most Important!)
This is the most critical measurement for dog sweaters and coats. Measure around the widest part of your dog’s chest, typically right behind the front legs. This is where dogs carry most of their weight and where fit matters most.
Pro tip: Have your dog stand naturally on all four legs. If they’re sitting or lying down, the chest measurement won’t be accurate.
3. Back Length
Measure from the base of the neck (where the collar sits) to the base of the tail. For dog sweaters, coats, and hoodies, this determines how much coverage your pup gets.
Pro tip: Keep the tape along the spine, following your dog’s natural back curve. Don’t press down on the fur.

What If Your Dog Is Between Sizes?
Always size up. A slightly loose dog sweater is more comfortable than one that’s too tight. Dogs need room to move, breathe, and do their business without restriction.
According to AKC breed standards, dogs with deep chests (like Greyhounds or Dachshunds) should prioritize chest measurement — it’s usually the deciding factor.
Special Sizing Considerations by Body Type
Barrel-Chested Dogs (Bulldogs, Pit Bulls, Pugs)
These breeds have wide chests relative to their length. Focus on chest girth first, then back length. You may need a size larger than their weight suggests.
Long-Bodied Dogs (Dachshunds, Corgis, Basset Hounds)
These pups need extra back length coverage. Look for “long” or “extended” sizing options, or size up for adequate coverage.
Large & Giant Breeds (Great Danes, Mastiffs)
Giant breed dogs often struggle to find dog clothes that fit. That’s why we carry sizes up to 5XL — because big dogs deserve cozy sweaters too! Check out our large dog clothing collection.
Quick Measurement Tips

- Re-measure puppies every few months as they grow
Frequently Asked Questions
How tight should a dog sweater be?
You should be able to fit two fingers between the garment and your dog’s body at any point. The ASPCA recommends checking that clothing doesn’t restrict breathing, movement, or bathroom needs.
Should I measure with or without my dog’s collar?
Remove the collar for the most accurate neck measurement. Add about 1 inch if your dog will wear a collar under the sweater.
