The Holee Roller can be used as a play toy or even a treat dispenser, put some bones in there and you have a dog that is locked on target! We like these because they are DURABLE. The rubber is pliable but far from weak or brittle, the ones we had in test came back without any damage other than a few tooth marks, and they were left with dogs that are known destroyers. However please note these are not indestructible and we do not recommend leaving the dog alone with these. Dogs can chase and roll around this toy, it gives them hours of fun and keeps them busy! We also have the EXTREME version of this toy that is very HEAVY DUTY. Have a dog that is hard on toys? Try the Extreme! Rubber gives it strength, bounce and a soft texture while the unique open design allows you to stash small treats or kibble inside for hours of entertainment for your dog. A do-it-all multipurpose dog toy! Its a fantastic treat ball, wonderful training aid, great for fetch, toss and tug, chewing and teething.
