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.

Beaded Collars

  1. Measure Around the Head
    Measure snugly, but not too tight, around the largest part of your dog’s head. Start in front of the ears, go under the jaw, around the muzzle area, and back behind the jaw like sliding a necklace over the head.
  2. Measure the Neck
    Measure around your dog’s neck where the collar will naturally sit.
  3. Use the Larger Measurement
    Use the larger of the two measurements when selecting your size.

Please use a soft, flexible measuring tape or string. Do not use a hard measuring tape.
