This toy is absolutely amazing for my Pit Bull who chews through every other toy she gets! After months of use, there's hardly a scratch on it! One day after she was chewing on it, however, I noticed that there was blood down in a couple of the grooves on one of the ends of the toy from her chewing too aggressively. But, with less time with the toy and more supervision, everything has been perfect since and the toy is over a year old!
