G-W_004. Measure Once.

Get the fit exactly right.

A well-fitted harness moves with your dog and stays put through a lunge. Measure once, match it to the tables below, and you're set.

How to measure

01

Grab a soft tape

Use a soft measuring tape or a length of string you can lay flat against a ruler afterward.

02

Measure while standing

Keep your dog standing calm and level. Wrap the tape snug against the coat — not tight, not loose.

03

Between sizes? Size down

Our fit runs generous. When a measurement lands between two sizes, choose the smaller for a secure hold.
