If you love your dog…don’t buy this.
Color: Orange
We have a nonaggressive English cocker. She opened the ball every time she played with it. And yes, we are closing it as hard as we can. I do not recommend this toy for any dog! This is a dangerous toy for a dog that is not supervised.

dog ball
Color: Blue
This ball is perfect for keeping my dog active and entertained. It's made of strong, durable material, ideal for games of fetch. It doesn't break easily and is light enough for him to carry in his mouth without any problem.

Fun but not for rough play.
Color: Orange
The ball contented our “golden” Jaxson for about 15 minutes. He then thought it was a regular ball and it’s just a little delicate for a big dog. I just wrote it off as a loss. Great idea but should be more durable.

Long lasting charge!
Color: Orange
My 50 pound goldendoodle absolutely loves this ball. It keeps a charge for a long time. It turns off
When it’s not being used and we play with it every day.!
