Virtually indestructible
Size: 8 Inch, Color: Red
Long lasting ball for a large dog. Bought the first one a few years ago. Its been outside all this time, still full of air and was virtually impossible for my large dog to destroy it. The weather affected the surface so ordered a new one. This has outlasted all the other balls.

Great toy for larger dogs
Size: 8 Inch, Color: Pink
This is holding up pretty well with my Great Pyrenees pup. She was able to pull all of the tags off-but the ball is intact for several weeks!

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
