Sizing

Reversible Harnesses

This size chart is for our reversible dog harness, which is made for dogs 36 lbs. and under.

When your human measures your chest, have them measure right behind your front legs.

Size	Neck	Chest	Weight Range
XS	8-10.5"	13.5-18"	4-8 lbs
S	10-12.5"	17-20.5"	7-12 lbs
M	12-14.5"	19.5-25"	12-23 lbs
L	14-16.5"	21-28.5"	18-27 lbs
XL	16-18"	23.5-32"	24-36 lbs

Classic Harnesses

This is for our classic dog harnesses, which are designed for dogs 36 lbs. and under.

When your human measures your chest, have them measure right behind your front legs. The sizing is slightly different than our reversible harness, with most sizes running a little smaller in the chest. The correct size is, in most cases, the same size worn in the Beast & Buckle reversible harness, but please note that there are slight sizing differences between harness types.

Size	Neck	Chest
XS	8" - 10.5"	12" - 15"
S	10.5" - 13"	15" - 18.5"
M	12" - 14"	16.5" - 22"
L	13" - 15"	20.5" - 28.5"
XL	14.5" - 17"	23" - 33"

No Pull Harnesses

The No Pull Harness line has unique sizing that is different from our other harness lines.

When your human measures your chest, have them measure right behind your front legs. The neck measurement, however, will be the most likely determinant of size for most dogs. It is possible for a small. stocky dog to wear the same size as a heavier, but leaner, dog.

The typical weight range will provide the accurate size for 95+% of dogs, but we recommend always checking the neck/chest measurements to be sure of the best fit.

SIZE	NECK	CHEST	TYPICAL WEIGHT RANGE
S	12" - 17 1⁄2"	14" - 23 1⁄2"	15lb - 25lb
M	14" - 19 1⁄2"	15 1⁄2" - 28"	25lb - 50lb

Big Dog Harnesses

This size chart is for our Big Dog harness, which is built for the unique physiological needs of dogs 50-130 lbs.

When your human measures your chest, have them measure right behind your front legs. The neck measurement will be the most likely determinant of size for most dogs - it is possible for a stocky 50 lb. dog and a lean 75 lb. dog to wear the same size.

As long as the neck/chest measurements fall in the listed ranges and your weight does not exceed the max. pull strength, the harness will be safe for you to wear.

SIZE	NECK	CHEST	MAX WEIGHT
L	15 1⁄2" - 23 1⁄2"	21 1⁄2" - 32 1⁄2"	90 lb.
XL	21 1⁄2" - 33"	28" - 39"	130 lb.

Collars

This size chart is for our dog collars, which are available in sizes for dogs ranging from 15-130 lbs.

Collars fit different ranges, with overlap between sizes. If your neck fits two different sizes, pick the collar width that you prefer.

Size	Neck	Collar Width
Medium-Sized Dog	13-20"	.78"
Big Dog	16-26"	1"

 

Hoodies

This size chart is for our dog hoodies, which are designed for dogs 10-40 lbs.

When your human measures your chest, have them measure right behind your front legs. The correct size is, in most cases, one size larger than the size worn in the Beast & Buckle reversible harness. If you wear a Medium harness, for example, we recommend starting with a Large hoodie.
