Although the extra-small harness has slightly fewer adjustments than the four larger sizes — it can still be articulated to your dog’s specific needs. The small harness covers a broad range of dogs within the range of 10-25 pounds. It is our most recent addition to our harnesses but can be very helpful in maneuvering all small breeds of dogs and also some larger cats! Select a dog harness size based on your dog’s weight first, then take measurements for accuracy. If your dog’s weight is on the cusp of our dog harness sizes, we recommend sizing down.
