K9 Booster Block | Sizing & Comfort Insert
Regular price
$ 12.95
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.
PRO TIP: The size of the booster corresponds with the size of your carrier. Use Med/Large for all XL and XXL carriers
