Sizing Guide

Good to Know: Every collar has its own sizing chart. Always check the chart on the product page you're shopping, as fit varies between styles.

✦ Neck Circumference

Measure around the base of your pet's neck where the collar naturally sits. The measuring tape should be snug but not tight—you should be able to fit two fingers comfortably between the tape and your pet's neck.

That's the sweet spot: secure enough to stay put, never tight enough to bother them.

✦ Chest (For Harnesses, Apparel & Select Products)

Measure around the widest part of your pet's chest, just behind the front legs.

If your pet has a broad chest or is between sizes, choose the larger size for a more comfortable fit.

✦ Back Length (For Apparel)

Measure along your pet's backbone from the base of the neck (where the collar rests) to the base of the tail.

Back length is the main measurement for clothing, though it's worth checking the chest too for the best overall fit.

✦ Measure your pet while they are standing whenever possible.

✦ A soft measuring tape gives the most accurate result.

✦ If you're between sizes, we recommend sizing up.

✦ Puppies, kittens, and young pets grow quickly, so measure again before ordering.
