Multi-functional Dog Toy This is a multi-functional and interesting toy for dogs that combines teeth grinding, squeaky sound, and retrieval training. Dogs can use it as a chewing toy or for agility training both indoors and outdoors. It can help dogs pass the boring time and enhance their happiness. Teeth Grinding and Cleaning Function The toy is made of food-grade TPR material, which is highly elastic and durable. The wave-shaped protrusions on the surface of the toy effectively friction off food residues, dirt, and tartar in the dog's mouth while they chew on the toy. It helps clean the dog's incisors, canines, and molars, promoting good oral hygiene for your dog. Squeaky Dog Toy When chewed by the dog, the toy makes a squeaky sound, which attracts the dog to play with it. The sound stimulates the dog's body and brain to move together, not only soothing their emotions and stimulating their spirits, making the dog happier, but also enhancing their intelligence.

Maintaining the happiness of your dog is of utmost importance. Safe Material This toy is made of food-grade TR material with high elasticity and toughness.
