1. How to Measure the Neck

Locate where a collar naturally sits, right above the shoulders at the lower neck. Wrap a tape measure around the circumference of your dog's neck.

Apply the two-finger rule: make sure you can comfortably slide two fingers between the tape and your dog's skin. The tape should be snug but not tight.

2. How to Measure the Chest

Locate the widest part of your dog's rib cage, usually right behind the front legs at the deepest part of the chest. Wrap the tape measure all the way around the torso.

Pull the tape snug against the fur without squeezing tightly. Apply the two-finger rule to allow room for comfort.

3. In between sizes? Our recommendation is to size up!
