It’s empty in here!
My dogs have had two of these for atleast 3 years now. They've survived many foster dogs and lots of chewing. For the price, I'm very pleased.
The dog wasn't very fussed when this toy originally arrived. When he did decide to play with it he promptly chewed the entire thing into marble sized pieces. I'd have given it fewer stars but it's not the products fault my dog is a toy destroyer. I'm sure a dog who is more gentle with toys would do well with this toy.
This toy is very strong and robust. I smear it with cream cheese or wet dog food and my dog spends ages chewing it clean. It keeps her entertained and helps clean her teeth at the same time.
