A good alternative to a regular kong. The dog likes chasing it around. Not sure about the 'teeth-cleaning' grooves around the edge, they are messy to fill and hard to clean and as she just licks them they don't do much to clean her teeth!
Bought this for an 8week old puppy. The treats tend to fall out but she loves the texture of the ball and the fact that it rolls well keeps her well occupied. A good buy.
