Size & Fit Guide
Size & Fit Guide
A better fit starts with a simple measurement.
Find the right collar or harness size for your dog, and the leash that matches how you move together.
How to Measure
Measure while your dog is standing naturally.
Use a soft measuring tape and keep it close to the coat without pulling tight.
Neck Girth
Around the base of the neck, where a collar or harness naturally sits.
Chest Girth
Around the widest part of the rib cage, just behind the front legs.
Fit rule: leave room for two fingers between the tape and your dog.
More measuring tips
- Keep your dog standing in a relaxed position, so the measurement reflects how the gear fits during normal movement.
- For neck girth, let the tape rest close to the coat without pressing into the skin.
- For chest girth, keep the tape level around the body and avoid measuring too close to the armpit.
- For harnesses, use neck and chest girth together. Chest girth matters most.
Collar Size Chart
Choose by neck girth first.
The collar should feel secure around the lower neck, without pressing into the skin or slipping over the head.
| Size | Neck | Width |
|---|---|---|
| S | 10–14 in26–36 cm | 0.75 in2 cm |
| M | 14–20 in36–50 cm | 1 in2.5 cm |
| L | 20–26 in50–66 cm | 1 in2.5 cm |
Fit check
After fastening the collar, you should be able to fit two fingers comfortably between the collar and your dog's neck. It should feel secure, but never tight.

Breed examples are only a reference. Dogs of the same breed vary by age, coat, body shape, and weight, so measuring your dog is always the best way to choose.
Harness Size Chart
Choose by chest girth first.
This chart applies to every Soul and Tail harness, including the Daily Roam Harness and Trail Leap Harness. If your dog is between sizes, choose the larger size.
| Size | Neck | Chest |
|---|---|---|
| S | 11–16 in28–40 cm | 17–22 in44–56 cm |
| M | 14–20 in36–50 cm | 21–27 in54–68 cm |
| L | 18–26 in46–66 cm | 26–32 in66–82 cm |
| XL | 20–31 in52–80 cm | 31–45 in80–115 cm |
Fit check
A well-fitted harness sits flat against your dog's body without rubbing behind the front legs. Once adjusted, it should feel secure while still letting your dog walk, sit, and turn naturally.
Between sizes? Choose the larger size, then adjust the neck and body straps for a secure, comfortable fit.
