How to Measure Your Dog
Getting accurate numbers is the most important step. Here's exactly where to place the tape for each measurement. Measure your dog standing up on a flat surface.
Neck
Wrap the tape around the base of the neck, where a collar would naturally sit. Snug but not tight. You should be able to fit two fingers underneath.
Chest (Girth)
Measure around the widest part of the ribcage, right behind the front legs. This is the most important measurement for harnesses and coats. Make sure the dog isn't holding its breath.
Back Length
Measure from the base of the neck (where it meets the shoulders) to the base of the tail. This matters for coats and jackets. Keep the tape straight along the spine.
Snout (for muzzles)
For circumference, wrap the tape around the snout at the widest point with the mouth slightly open. For length, measure from the eye line to the nose tip. The dog must be able to pant with the muzzle on.
Common Measurement Mistakes
- Measuring over a thick coat. Press the tape close to the body. Winter coats add inches that throw off sizing.
- Using collar size for a harness. Harnesses need chest girth, not neck size. These numbers are different.
- Measuring a sitting dog. Chest and neck measurements change when dogs sit. Always measure standing.
- Pulling the tape too tight. The tape should be snug against the body, not compressing the fur or skin.
- Guessing instead of measuring. Even if you think you know your dog's size, measure. Breed averages don't account for individual variation.
Brand Fit Tendencies
Not all brands fit the same. Here's what dog owners report about how major brands fit different body types. These are general tendencies, always check the specific product's size chart.
| Brand | Runs… | Best For | Watch Out For |
|---|---|---|---|
| Ruffwear | Narrow in chest, longer cut | Sighthounds, deep-chested breeds | Too tight for barrel-chested dogs like bulldogs |
| Kurgo | True to size, roomy chest | Broad-chested breeds, stocky builds | May be too loose for narrow dogs |
| Blue-9 Balance | Highly adjustable | Mixed breeds, hard-to-fit dogs | More buckles to manage |
| 2Hounds Design | Good adjustability, front-clip | Pullers, dogs with neck sensitivity | Runs slightly large, may need to size down |
| EzyDog | Roomy, padded | Active dogs, broader chests | Can be bulky for small breeds |
| Embark | Standard fit, budget-friendly | Average builds, first-time harness buyers | Less adjustability for unusual proportions |
| Canada Pooch | Slim cut, tailored | Narrow breeds, small dogs | Not ideal for barrel-chested or broad dogs |
| Muddy Paws | Roomy, good for coats | Thick-coated breeds, winter gear | Harnesses may run large |
| Baskerville | Muzzle specialist | Brachycephalic breeds (pugs, bulldogs) | Muzzle-only brand |
| Cosmos | Snug fit muzzle | Long-snout breeds |
These notes are based on aggregated feedback from dog owners and breed-specific communities. Individual product lines may vary. When in doubt, measure and check the brand's own chart.
Common Breed Fit Challenges
Some breeds are notoriously hard to fit. Here's what to watch for with popular breeds that often struggle with standard sizing.
Greyhounds & Whippets
Deep chests, narrow waists, and slim necks make most harnesses bunch up or slip. Look for brands with adjustable chest straps and a longer cut. Ruffwear's Web Master or Front Line harnesses tend to work well.
Bulldogs (English & French)
Barrel chests, wide shoulders, and short necks mean most harnesses are too tight in the chest but loose at the neck. Prioritize chest girth over neck size. Kurgo and EzyDog tend to accommodate this shape.
Dachshunds
Long backs and deep chests create a tricky combination. Step-in harnesses often work better than overhead styles. Make sure any coat doesn't restrict movement along the spine.
Corgis
Low, long bodies with a deep chest. Overhead harnesses can slip forward. Step-in or front-clip styles with a chest strap that sits behind the legs work best.
Pugs & Flat-Faced Breeds
Standard muzzles often don't fit at all. You need basket-style muzzles designed for brachycephalic breeds. Baskerville makes options that allow panting. Never use a restrictive muzzle on a flat-faced dog.
Standard Poodles
Deep chests with light builds. Harnesses designed for broader dogs will gap around the ribcage. Look for highly adjustable options like Blue-9 Balance.

Need a Measuring Tape?
A soft measuring tape makes all the difference. Rigid rulers or yardsticks won't wrap around your dog's body accurately. A basic fabric tape measure costs a few dollars and gives you measurements you can actually trust.
