We have a frisbee loving & destroying Vizsla. We have tried the standard (good for about a day) the dollar store (good for 10 minutes) and the Nylabone (good for a few days but lots of chunks missing). He doesn't get to have them to chew up; he can just destroy them bringing them back to us. This one seems to be lasting. After a few days, he brought it back folded in half, and I thought that was the end of it, but it popped right back to shape without a mark on it. I am impressed and plan on ordering more of these.
