Good toy to keep your dog busy. Make sure you check it periodically to ensure it stays together.

My puppy’s favorite
Color: Orange
Great quality and built to last. My dog really enjoys playing with it and stays entertained for quite a while. The material is strong yet safe, and the included drawstring bag is a convenient extra for easy storage.
Is colorful and my become my puppy’s favorite.

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.

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.!
