Update Dec 2025, still going! This toy has been the subject of much squeaking and death shakes... And more than one tug o' war... And other than looking a little dingy even after washing it's as good as new! No missing bits, no noticeable damage. I have several in the brand, both the larger version for my mastiff, and other styles for the medium-sized dogs. I started buying online because the one store that carries it moved further away. Outshines all other brands I've tried for durability and fun play. In 5years and 9 dogs only 2 have needed replacement. Worth the price!!!
