We have an 8 year old female Golden. She FOUND her large jive ball in Arizona. As with other pets on this site, she would absolutely destroy any toy we bought for her! Tennis balls...well, she loves to skin them with her incisors! This Jive ball is almost indestructable. After months of gnawing on it, she has a few tooth marks on it, but it's still very good. It is her favorite toy and she begs us to throw it for her all the time. Highly, highly recommended from Chinook, for sure!
