Although your dog might want to use it as a doggie yoga block, it’s designed to work with the K9 Sport Sack Air Forward Facing Backpack Dog Carrier.
Works great with this backpack. Keeps my Italian Greyhound mix from having to stand on her toes to look over my husband's shoulders. Good fit for all of us.
We tried a small and she couldn’t fit into it and then a medium and she still didn’t fit so I purchased this block and now she fits! I’m really happy!
Makes the K9 Sport Sack very comfortable for my miniature poodle.
I put 3 of these in a pillow cover. My newest kitty is an adult but very tiny (he was a stray so maybe stunted growth?). I wanted a thick foam but not one he would sink into. My other cats can sit in their room and look out the window. He couldn't. ..till now.
I'm glad that I got the booster for fozzie so that he would have leverage while sitting in the sport sack. He still has a lot of room inside the sack.
Bought the bag a little big since my dog is still growing, this booster makes him fit in it. I recommend just getting the booster instead of using a rolled up towel, since the booster fits so much better.
