Chicken Liver
Liver, an organ meat rich in vitamins and minerals, which pets tend to like.
Liver is one of the most nutrient-dense foods there is: rich in vitamin A, B vitamins, iron and copper. Dogs and cats also like its taste, so it’s used in wet foods and treats partly for that.
Because liver holds so much vitamin A and copper, a complete food uses it in measured amounts. Home diets and treats heavy in liver can provide too much over time, so count treats as part of the day’s food, and ask your veterinarian before adding a lot of it.
Also written as: Beef Liver, Pork Liver, Turkey Liver, Lamb Liver, Duck Liver, Salmon Liver, Dried Chicken Liver.
