  1. Make sure your dog is standing then measure your dog's back length (1) from the withers (right between the shoulder blades) all the way down to the base of the tail (where it connects to the spine).
  2. The chest (2) measurement should be taken from just behind your dog's front legs. Wrap the tape measure all the way around your dog's chest. We recommend adding a further 5-20cm (tiny to large breeds) to this measurement to allow for unimpeded movement.


  1. You should not measure any part of the neck or the tail in your back length measurement. 
  2. Between sizes? The odds are the size down is the right jacket to go for and NOT the size up.
