My Golden Retriever destroyed this ball within a couple hours of receiving it. Turned my back for a minute and she had it open and chewed on the internal part wrecking the charging port. Then proceeded to rip chunks off of the outer part. This is a great idea but maybe make it more difficult to open. BTW, my dog loved the ball when it was functioning properly.

Great Interactive Toy

Color: Blue

This toy is amazing for keeping my dog entertained and active! The movement feature really grabs my dog’s attention, and he loves chasing and playing with it. It is strong and durable, and the design is very cute. It’s also great for preventing boredom, especially when my dog has extra energy. The battery lasts a good amount of time and it was very easy to set up. My dog plays with it every day and hasn’t gotten tired of it. I highly recommend this toy to anyone who wants a fun and interactive way to keep their dog happy and busy!

Pricey otherwise enjoyable

Color: Red

Ball is made of a durable type material kinda like a foam only not chewable, at least not yet Very entertaining and has a whining noise, it does bounce a little bit and moves somewhat when nudged by dog. Bouncy. Not a very high bounce so it keeps close to ground. The ball was fully charged when it arrived and has entertained her for about an hour now that she has settled down so it did what I hoped it would do, to keep herself busy to the point of being tired. At best I would not leave this lying around for heavy chewing use only for entertainment or play time.

Mostly Good toy. Could be great.

Color: Blue

The ball looks well made and the dog absolutely loves it. He can't stop playing with it. It's awsome to see. The only problem, abd it's a big one, is that we can't open the ball to turn it off. The two halves are stuck together and don't budge. I'll wait until battery dies and try then.
