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 |
| S | 10-12.5" | 17-20.5" | 7-13 lbs |
| M | 12-14.5" | 19.5-25" | 12-20 lbs |
| L | 14-16.5" | 21-28.5" | 18-27 lbs |
| XL | 16-18" | 23.5-32" | 25-36 lbs |
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 |
| XS | 10" - 13" | 11" - 22" | 10lb - 15lb |
| S | 12" - 17 1⁄2" | 14" - 23 1⁄2" | 15lb - 25lb |
| M | 14" - 19 1⁄2" | 15 1⁄2" - 28" |
25lb - 50lb |
| L | 15 1⁄2" - 23 1⁄2" | 21 1⁄2" - 32 1⁄2" | 50lb - 80lb |
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. |
