Colossal Chicken Dinner Made with big chunks of chicken and hand-stuffed peas and carrots in gravy. New Merrick Chunky Cans are the next evolution in Merrick's history of innovation – four new canned recipes for dogs featuring big chunks of meat, hand-stuffed real vegetables like carrots and potatoes and hearty gravy. All four new recipes are 100 percent grain-free, feature deboned meat as the No.1 ingredient and are made in the USA in Merrick's own kitchen with no ingredients from China.
