Good product. My dog is very entertained and stimulated by playing with it.
Color: Green, Size: Small (2.0 in, Pack of 2)
I'M AMENDING THIS REVIEW AND ADJUSTING THE RATING UPWARD! Though it took my dog a little while to adjust to how differently this ball behaves, HE LOVES IT NOW. I wish I could give you a sense of how enjoyable and comically entertaining it is to play with him using it. ORIG. REVIEW: Bought this for a little 8 lb. aggressive chewer who loves to play fetch. I initially bought the 2" Chuckit! Ultra ball previously. It is the most amazingly durable product I've found for this pup. Very firm, but not hard on his teeth. He's very quick and agile, so I thought he would like the eye-mouth coordination challenge of a ball that changes direction suddenly. I guess my only disappointment with the product is that the ball is hollow instead of having a solid core like the Ultra ball, so he doesn't enjoy chomping down on it the same way. The erratic bounce feature is entertaining, but the pup is a little skittish, so he was intimidated at first. He's warmed up to it, but not with the same enthusiasm as the Ultra ball. Having said all this, I don't fault the product for the rating I gave it. It is a quality-made product that performs as advertised. I just didn't anticipate that my dog would be less enthusiastic than I thought.

Highly entertained golden retriever!
Color: Green, Size: Large (3.0 in, Pack of 1), Color: Green, Size: Large (3.0 in, Pack of 1)
My golden retriever spends hours chasing this ball. Its erratic bounce pattern keeps him engaged and guessing where to chase the ball. It is durable and stands up to chewing well.

Great quality ball
Color: Green, Size: Medium (2-1/2 in (Pack of 2))
The product is great no issues. It’s very durable. All of this brands products are strong and durable. The only reason I gave it a four star is I think my dogs prefer more the blue round balls. So that being said, I won’t buy these anymore, but they love the blue ones whether they’re the recycled or not. Great company!
