Abstract:
L. L. Wren founded the Siler City Milling Company in 1910. The company originally milled flour and corn meal, but in the 1920s, began to manufacture their own pet foods and animal feeds. Siler Mills is one of the nation's largest companies that produces and markets its own dry dog food under the brand names of \"Chatham\" and \"Champ.\" It also controls its products from the farm to the marketplace.
