This toy is very amazing. It withstands the constant tugging of multiple dogs all day long at our boarding facility. This is the toy that lasts the longest out of any toy we've bought, and the dogs LOVE it!!! It is not meant to be used as a "Chew Toy" though... if you have a dog who is a heavy chewer, the Bumi is not the toy for you. But, we don't let the dogs chew on them, so they last for months!
