Since 1955, Nylabone has been an expert in why dogs chew and creating dog-approved products for every breed, shape, and size. Made of tough nylon, our Power Chew durable chew toy challenges aggressive chewers. This long lasting chew toy provides ongoing enjoyment, satisfies the natural urge to chew, and encourages positive chewing habits. Plus, the ridges and nubs on this dog chew bone promote clean teeth and fresh breath as your dog chews. Different dogs have different chewing styles and strengths, even within the same breed, so be sure to choose the correct chew toy size and strength for your dog.
