K9 Booster Block | Sizing & Comfort Insert

My dog kept sliding around in the carrier on our hikes, so I grabbed this insert to give him a bit more room. The 3 inches it adds really helped him sit in a more natural position, and he seems way more comfortable on longer walks now.

My dog was swimming inside the medium carrier, but popping this block in lifted her just enough that she finally rides comfortably on my back. The three inches of extra depth really anchors her hips without cramping the space. Definitely worth the small cost to fix the fit.

The 3-inch boost made all the difference for my pup’s posture, and the insert is firm enough to hold shape but still comfy against his chest. Fits snugly into the sack without bunching, so he finally stops squirming on every hike.
