I must say I was very surprised with the durability of this toy. We've had it for 3 days and not one puncture hole. My rescue is a destroy chewer that doesn't care for Hardy chew toys unless it squeaks. While the squeaker isn't the best, he still loves it. We put peanut butter in the grooves for him and he goes to town. Will purchase again should he ever destroys it, worth the price!

Great toy, heavy, good size, and durable for active chewers. My two dogs like to play tug a war a lot and this toy has held up fantastically! Afterwards they tend to chew toys to pieces but this one has stood the test of time so far. Great buy!
