Gummiknochen

My labrador drags this rubber bone around the yard every single morning, and it's taken a serious beating without a single crack. The material feels dense enough that I don't worry about her shredding it, and she'll chase it for a solid half hour before she finally flops down.

My Border Collie is obsessed with this bone—she chews it for hours and still wants more. The rubber holds up great against her aggressive chewing, and it’s perfect for a quick game of fetch in the backyard.

My Lab has been playing fetch with this bone every evening for two weeks straight, and it still looks brand new. The rubber is dense enough to survive his aggressive chewing but soft enough that he actually wants to carry it around. Definitely worth it for the exercise it gives him.
