This Second Track item will be a mystery color, slightly used, but still has lots of life left in it. You might find a few pieces of fur or a bit of dirt on it, but your dog won't mind. If you won't be happy with any color harness, head on over to our full-price harnesses, where you can choose whatever color you want.

Two e-coated iron d-ring attachment points
Top handle for control or assistance over objects
Reflective strips on handle for night visibility
Lightweight & breathable
Overall weight: S = 4.85oz, M = 6.7oz, L = 8oz, XL = 11oz

Sizing

Dog silhouette guides measuring for (Used) Harness; includes collar and harness size chart.

When measuring the chest: Be sure to measure around the widest part of your dogs chest - right behind the front legs!

When measuring the neck: Be sure to measure around the widest part of your dogs neck - at the base where the harness will sit, not where a collar sits!

If your pup falls between sizes or they are still growing or filling out, we recommend sizing up!

*Heads up! Our harness sizing has changed: We added a 'S' size - what was previously labelled as 'S/M' is now just 'M', and what was previously labelled as 'M/L' is now just 'L'. Please be sure to measure your pup!

Recommended Fit

To put the harness on, simply slip the harness over the dog's head, and clip the two side release buckles at the chest - all 4 paws stay on the ground! Both the neck and shoulder straps are fully adjustable. We designed our harness to fit a bit shorter for maximum breathability. Make sure your pup has enough space between their armpit and the straps, and its a snug but comfy fit!
