Our hemp dog rope toys are handmade. These dog chews help improve a dog's dental health and provide hours of fun. Our rope toys are meant to be played with, carried around, thrown, tugged, etc. The strings that naturally form will help to floss the teeth when the dog carries it around and plays with it. It is NOT FOOD, and not meant to be swallowed or injested. We feel it is a great, natural hemp healthy toy if played with interactively. Dogs love interaction. Eventually, this hemp rope ball toy will unknot and become rope again, it is also fun for the dogs to undo the knots, like a puzzle! This ball is 4 inches x 4 inches!
