Size Guide
Find the Right Fit
Choosing the correct size helps keep your pet comfortable and secure. Always use the measurements listed below rather than relying only on breed or weight.
Use a soft measuring tape and make sure it sits comfortably without pulling too tightly. If your pet falls between sizes or is still growing, we generally recommend choosing the larger size.
Trek Harness
Choose your dog’s harness size primarily by measuring the widest part of the chest, directly behind the front legs. Weight can be used as a secondary reference.
| Size | Recommended Weight | Chest Girth |
|---|---|---|
| S | 15–30 lb | 17–24 in |
| M | 25–55 lb | 22–31 in |
| L | 40–75 lb | 26–35 in |
| XL | 75–105 lb | 31–41 in |
How to measure
Wrap a soft measuring tape around the widest part of your dog’s ribcage, directly behind the front legs.
The tape should be secure but not tight. If your dog falls between sizes, choose the larger size for a more comfortable and adjustable fit.
Collars
Measure around your dog’s neck where the collar would naturally sit.
You should be able to comfortably fit two fingers between the collar and your dog’s neck.
| Size | Neck Girth |
|---|---|
| XS | 9–13 in / 23–33 cm |
| S | 12–16 in / 30–42 cm |
| M | 15–20 in / 38–51 cm |
| L | 18–22 in / 45–56 cm |
| XL | 20–25 in / 50–62 cm |
If your dog falls between sizes, choose the larger size and adjust the collar for a secure fit.
Please double-check your pet’s measurements before purchasing, particularly when ordering an engraved or personalized collar.
