Bought for my miniature schnauzer. She didn’t know what to think at first but loves it now. It’s so much fun watching her play and keeps her busy! My dog isn’t much of a chewer and loves the movement/chase of this toy. Wouldn’t recommend for big dogs or chewers as there’s a plastic piece that can come off.

I just recieved this yesterday 5-23-2026. My new puppy loves it. But after it stopped working and I went to recharge it. it just will not recharge. I currently have it still trying to recharge. so I am not sure what to do other than trying to charge it. I may need to look for something else.
