My gang loves this food and even I could eat their Chicken Potpie

Merrick Pet Food
Named as Best Pet Food of the Year
2006-2007
The Glycemic Research Institute in Washington, D.C. announced today that they have selected Merrick Pet Food as the Best Pet Food of the Year for 2006.
The coveted Best Pet Food of the Year for 2006 was awarded to Merrick Pet Food for “Turducken,” Grammy’s Pot Pie,” and “Thanksgiving Day Dinner” Gourmet canned dog food. This is the second year in a row that Merrick’s Pet Food products have won the accolade as Best Pet Food of the Year.
The senior staff and associate research fellows of the Glycemic Research Institute (GRI) provide Pro Bono Glycemic Certification Marks for products that pass the strict criteria for “Low Glycemic” foods. The Federal GRI Seals of Approval are based on ongoing clinical studies (In-Vivo) that determine the glycemic index, glycemic load, diabetic, and fat-storing properties of foods. Determining how humans and animals metabolize foods allows scientists to gain insights as to the varying effects different foods have on metabolism and longevity.
For the past 20 years, GRI has been the industry leader in glycemic research, receiving the first glycemic patent ever awarded. Glycemic Solutions, the Official Clinical Testing facility for the Glycemic Research Institute, conducts Human In Vivo Clinical Studies for the food and nutrition industries.
The Glycemic Research Institute (GRI) examined hundreds of pet foods in 2005 to determine the healthiest overall product, focusing on anti-aging, diabetes, arthritis, glycemic, blood glucose and insulin response in the canine.
As a Non-Profit independent research organization, GRI has no ties to the pet food industry, and does not accept monies from any company for the Pet Food of the Year award.
