Not the best for REAL CHEWERS.
Color: Blue
My dogs love to chew and these didn’t last too long. It did keep them busy and I probably will buy these again but don’t expect much resistance of yours have big dogs that love to chew toys.

Extremely hard and durable
Color: Blue
These are very hard , but my puppy lives them and my large dog can't tear them up, so that is a huge plus.

So cute and entertaining to watch!
Color: pink
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 stops working & doesn't recharge
Color: blue
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.
