If you've ever rushed an aggressive chewer to the vet following a disembowelment of a plush dog toy- you know avoiding synthetic materials and plastic squeakers is essential for certain dogs and a good precaution for all dogs. Enter these rugged but natural dog toys handcrafted from 3 layers of thick American-sourced vegetable/tree bark tanned leather stitched together with 100% cotton thread. Natural fibers offer a satisfying chewing surface that cleans teeth and stands up to chewing much better than plush or woven fabric toys. Choose from bone, donut, barbell, or shoe shape. These heavy leather toys are toys, not edibles, and should not be left with aggressive chewers unsupervised. Made by hand in the USA by a family owned small business.
