This toy is truly amazing! Even when it's out of power, my little dog will play with it by itself. When I first got it, it barked at the toy for about an hour - probably because it was a bit confused and excited. But later, everything was fine. Now it has become one of the dog's favorite toys, and the only one. The quality is excellent, and it's really quite fun. It can be played with on its own to entertain itself, or it can be used for a tug-of-war game with another object - it's versatile. Our whole family loves it very much! Highly recommended.

Keep my dog busy.

Color: Remote blue

The duraspin dog ball bounces, moves, and vibrates automatically. My Labrador chased it all afternoon and never got tired of it.

Very impressed with toy

I love these, my family loves these and the cats love these. The only one who doesn't pay it any attention is the one it was intended for. Bought for our dog who has an obsession for stealing napkins or tissues or paper and eating it, we thought its be clever to get this squeaky newspaper toy for him to steal and have a field day with. It resembles the front page of every newspaper I have ever seen and the crinkle is superb, yet no dice. He sniffs it and turns his nose up at it. Our next goal is to wrap his favorite treat inside it and have him find it so then the toy is scented as his favorite treat. Other than that, this pack comes with 3 individual paper like crinkle toys and the imagery and words are clearly seen on it. Nothing is smudged or missing. Very impressed actually!

Not indestructible

The dog destroyed it in under 3 minutes. I mean he destroyed it and I am unable to receive a refund because I don’t have a product to return. Destroyed because it is a cheap piece of garbage.
