Collar Size Guide

Built for comfort. Engineered for strength. Sizes for every dog.

Whether your dog is a lean-and-mean trail runner or a heavy-hitting protector, we've got a collar that will fit.

How to Measure

Use a soft tape measure around your dog’s neck where their collar normally sits.

Allow room for two fingers between the collar and their neck—comfort matters.

If your dog is between sizes, we recommend sizing for adjustability.

Ruffneck Tip:

Our collars are rugged and adjustable, but for the best performance and comfort, don’t guess—measure. It’s the difference between "good enough" and gear that works when it counts.
