The Booster Block is an insert for the K9 Sport Sack which adds 3 inches of height for shorter, thicker dogs, growing dogs, or dogs that just need a boost in their current size. Made of high quality foam and removable, washable cloth.
Built to Last
For Growing dogs, In-between-er dogs, wide body - but short, or dogs that just need a little boost in their current size.
Booster Block size correlates with the size of K9 Sport Sack. The Booster Block is designed to be a tight fit in the K9 Sport Sack to ensure a snug and sturdy fit while in use. While using 2 blocks for 6" addition height is fine, we do not recommend using more than 2 Booster Blocks in a K9 Sport Sack.
