This is the greatest thing that's happened to my mom who loves our dog but hates the slobber! It's easy to pick up and chuck without having to touch the ball. And it's fun shape makes it interesting for our dog. She gets really excited every time we've brought it out so far. We found this product because we met a stranger at the dog beach using it and told us about getting it here. Buying it here saved us a couple of cents than buying it at the store (walmart, target, etc). We got a medium sized one for our 16 pound Dachshund mix and its the perfect size. It would be too big for a Chihuahua and too small for a adult lab. (I've attached an image to compare sizes to my 13" Macbook Pro of which I'm currently writing my review from haha)
