I have never before reviewed a product, but given how long my pup's Tux has lasted, I feel obligated to do so. He's had it about two weeks now, which may not seem like long, but for my 3 year old Belgian Malinois and his jaws of toy death, it's a miracle! My dog is the type of chewer that many get rid of...in addition to many other destroyed belongings, he ate through 5 dog crates and he tore the flooring out of my entryway, starting in the middle and working his way out. So, when I say he's a tough chewer, I mean he's a TOUGH chewer. Typical chew toy life around our place (with just the one dog) is about 10 minutes to 1 day. His Extreme Kong Bone was in about 20 pieces before I even had the groceries unpacked after bringing it home. If a chew toy happens to last longer than that, it's because it is so large he's taking it apart chunk by chunk. Even the very hard plastic bones get whittled away in no time. I have NEVER had a toy that lasted in its ORIGINAL shape, until the Tux. My dog's Tux is still in the same shape it was in two weeks ago when he got it, and I never take it away from him. He has carried that little blue toy around with him all over every day since. He chases it, bounces it, and lays down and power gnaws on it...and it only has a few teeth marks!
