All natural, pesticide free hemp rope tug toy. We do not add any colour or chemicals to our hemp products. They are made of 100% hemp and are naturally pest and mildew resistant. Sizes may vary slightly as these items are handmade. Dogs are naturally attracted to the smell of hemp products and should not be left unsupervised as they will chew these for hours at a time, substantially reducing the lifetime of the ropes. These are meant to be used as interactive tug/fetch toys, not a chew toy.
