K9 Sport Sack Booster Block

K9 Sport Sack Booster Block

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" (7.62 cm).

It helps make the K9 Sport Sack experience more comfortable for you and your dog.
