Sizing Guide.
Every dog is built differently. Use this guide to measure your pup and find the right fit across all our products. When in doubt, size up — comfort always comes first.
How to measure
your pup
Neck: Measure around the base of your dog's neck where the harness or collar will sit. Pull the tape snug but not tight.
Chest (for harnesses): Measure around the widest part of your dog's chest, just behind the front legs.
Two finger rule: Once fitted, you should be able to slip two fingers comfortably between the gear and your dog's body.
Harness Sizing
Our harnesses are adjustable, but getting close to the right size ensures the best fit and comfort. Measure both neck and chest for the most accurate result.
| Size | Neck (in) | Chest (in) |
|---|---|---|
| S | 13.4 – 16.9 in | 16.5 – 22.8 in |
| M | 13.8 – 18.9 in | 18.1 – 25.6 in |
| L | 16.9 – 22.0 in | 21.3 – 32.3 in |
| XL | 18.5 – 26.4 in | 22.8 – 34.6 in |
Collar Sizing
Collar fit is all about neck circumference. Measure snugly and remember the two-finger rule — you should always be able to fit two fingers between the collar and your dog's neck.
| Size | Neck Circumference | Collar Width |
|---|---|---|
| Small | 11 – 17.5 in | 0.6 in |
| Medium | 12.5 – 19.5 in | 0.8 in |
| Large | 16 – 26 in | 1.0 in |
Tactical Collar Sizing
Measure around your dog's neck where the collar will sit. Allow space for two fingers between the collar and neck. All tactical collars feature a 1.5 inch width for a bold, structured look.
| Size | Neck Size | Collar Width |
|---|---|---|
| Small | 15.5 – 20.5 in | 1.5 in |
| Medium | 17 – 23 in | 1.5 in |
| Large | 18.5 – 26 in | 1.5 in |
