“Eating one's own dog food” is a quality assurance tactic which means to use one's own products and services. It is attributed to Clement Hirsch, the eccentric erstwhile president of Kal Kan Incorporated, who (apocryphally) would pull the stunt of eating from a can of his company's dog food at shareholder meetings.
