This is our company's original patented product, which can also be used as a water toy. It's a newly designed pet dog chew stick with an original serrated edge and chewing channels around the toy, effectively cleaning the dog's canines, molars, and incisors, removing tartar. The channel in the middle of the toy can be used to thread a chew rope or to hold treats, making it a treat-dispensing toy. Overall, it serves both health and play purposes.
