Where was the dog bone invented?

The dog bone, as a specific product, does not have a singular point of invention, as various forms of dog chews have existed for centuries across different cultures. However, the modern dog bone, often made from synthetic materials and designed for durability and dental health, became popular in the United States in the early to mid-20th century. Companies like Nylabone, founded in the 1950s, played a significant role in popularizing these products.
