I must admit I was skeptical but bought several types to try on our golden retriever who demolishes everything. It doesn't take much-he has jaws like steel. He's had the Huck for two weeks now and loves it. He throws it in the air and then chases it. Chews on it when he gets tired and then falls asleep. Not one tooth mark in it yet. Fingers crossed. It's nice that he can't get the whole thing in his mouth and chew with his back teeth, which is what seems to destroy other toys. I love it.
