Booster

Sizing your dog for a K9 Sport Sack isn't an exact science. If your dog is in between sizes, has a wide body but short in length, or is still growing, the Booster Block fits snuggly in the bottom of your K9 Sport Sack to boost your dog up 3 inches. It helps make the K9 Sport Sack experience more comfortable for you and your dog.
