The product can be used as a water toy. Pet dogs complete the process of grinding, cleaning and playing with this product. The bottom of the toothbrush is designed to extend the shape of the dog's paws, which makes it convenient for pets to control the product with two front paws when using this product. The center of the toy is hollowed out, and there are small through holes connected to the inside on the outside. You can put pet toothpaste or attractant inside the toothbrush, which will flow out from the small hole when the dog uses it.
