Size guide

Measure once. Fit right.

Choose by chest first, then check back length. Between sizes? Size up.

How to measure your dog: chest and back length for each size
  1. Chest: around the widest part, just behind the front legs.
  2. Back length: from the base of the neck to the base of the tail.
