K9 Booster Block | Sizing & Comfort Insert
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.

Perfect! I bought this to give my pup a little boost in her sack and it works perfectly. She comfortably sits on it while carried and it gives her just enough boost for her to have a clear view of our environment. I love how it has a removable cover than can be washed.
Theses are perfect boosters for our little yorkies!!!
We recently got sport sack that was a bit too large for our smallest dog. So we decided to order a booster block so she can use it as well, the height is perfect and we love that it has a little squish to it so its very soft/comfy for her to be on for long distances.
The booster is the perfect little thing to have for a growing little one to be able to fit just right.
Forgot to get a picture on the trail, but so glad I got the booster! It just helps Jaxx sit a little higher on my back so his weight is better distributed for me. He's 13lbs but long legs, so he's in a medium sportsack with booster.
