"I would not recommend this to anyone with an aggressive chewer. We have a 45-pound pit bull who insists on chewing on the red side parts. She easily chewed a hole through one side within the first half hour. I cannot get her to pull on the rubber grips despite praising her every time she does and smearing the handles with peanut butter. Definitely disappointed - her black Kong toy is one of her favorites and has lasted about a year. I was hoping this would be of the same durability."
