This multi-textured Dual TPR (thermoplastic rubber) Bone is great for all chewing strengths. It consists of two types of 3D granular texture that not only promotes your dog’s dental health by scraping away any excess tartar, but also helps relax and relieve any anxiety they may have by massaging the gums. Satisfies both your dog’s natural predatory instincts to chew and their need for mental stimulation. Best for puppies and small to medium-sized dogs.
