So much fun
Size: 8 Inch, Color: Pink
Best money ever spent hours of fun. We have 3 dogs. They all love to play with this toy. We got the size 3 large is what we ordered. I'm not going to lie I thought it would be bigger when I ordered it. Two of our dogs are large breeds and the other is medium. It's not too big for the medium to play with it. It comes with a ball pump included so convenient. The little tabs are very durable. I can't recommend this enough. This has no squeaking or any sounds. It's nice that you can play with your four legged companion or you can have them play tug or just enjoy pushing the ball around. It is very versatile in play and stimulation.

Not for chewers
Size: 8 Inch, Color: Yellow, Size: 8 Inch, Color: Yellow
My dog managed to pop this and completely chew through it in a matter of 4 days. It was definitely cute and she loved the size of it but with her chewing all the way to the core we have to get rid of it. I thought it was a good material but I guess I was wrong. Kind of sad considering the money spent only lasted 4 days

Great dog toy
Size: 8 Inch, Color: Pink
The amount of stupid and cute these dogs look like when they shake this ball and smack their own faces! It took a hot second for either dog to understand where to bite on the ball, but now that they do, they both will play with it for a while. Great purchase, came with a pump to blow the ball up.
