Not as described

This item is vibrant in color, but I could tell right away, It wasn’t going to be durable and indestructible like the description said. My dog had it destroyed in less than a minute.

Comes with pump
Color: Colorful, Size: Large
My dogs enjoyed it but it’s not large dog proof. I have a husky and German Shepard…..the ball lasted a day before it was torn up. But this would be perfect for smaller or medium sized dogs.
