Say hello to Chaco Latte Hefner. Chaco works with his humans, Oz and Brenda Hefner, at Oz’s Jewelers in Hickory, North Carolina in the foothills of the Blue Ridge Mountains. The one-year old Shih Tzu goes to work every day and has spent most of his life in the store as the Love Ambassador to the customers. An important job since Oz’s Jewelers is a store built around the business of love. The popular Chaco is featured in a mural painted on the side of Oz’s. He even has a ruby set into his collar – “very securely,” says Oz.
