Pro Tip: If your dog is in between sizes, has a wide body but short in length, or is still growing, consider adding the Booster Block which fits snuggly in the bottom of your K9 Sport Sack to boost your dog up 3" (7.62 cm). It helps make the K9 Sport Sack experience more comfortable for you and your dog.
