The vocal design is happy when you bite, and the built-in generator attracts the dog’s attention and increases the fun of the dog’s play. The grinding teeth are bitten and wear-resistant, and the concave and convex shape of the “oval” particles on the surface helps the dog to maintain oral hygiene. Natural latex is flexible and does not hurt teeth, and is made of soft latex material, which is palatable and safer to play with. Toys that keep the dog from being lonely at home, don’t tear up the house and don’t suppress the emotional warming.
