Sizing your dog for the K9 Sport Sack® is not an exact science. If your dog is between two sizes, has a wide body but short length, or is still growing, the Booster Block will fit snugly into the bottom of your K9 Sport Sack and raise your dog 7.5 cm. This improves the experience of using the K9 Sport Sack for both you and your dog.
