The death of a 9-year-old Pomeranian from eating a dog treat is hardly "what nature intended," according to a lawsuit filed this week. An Illinois man has sued Nestle Purina Petcare Co and Wal-Mart Stores Inc, saying his dog died from eating chicken jerky treats that the defendants knew posed a substantial risk of illness or death. The federal lawsuit seeking class-action status was filed in Chicago o n W ednesday by Dennis Adkins, a resident of the Chicago suburb of Orland Park who owns a small trucking company.
