'Fresh meat' is a highly nutritious and palatable protein source for dogs. It usually consists of animal viscera (the internal organs and connective tissues) which is left over from the processing of human-grade animals. Despite not being exactly what most people have in mind when they think of fresh meat, it remains a high quality ingredient and is, after all, a very natural food for dogs.
Fresh meat is widely used in wet dog foods and is also becoming increasing popular in dry foods. When comparing the meat contents of dry foods it is important to remember that since fresh meat contains roughly 70% water (compared to just 5-7% in meat meal) it is far less nutritionally concentrated than meal and so more is required. For example, in order to provide the same levels of protein and fat as 20% meat meal a dry food would need 72% fresh meat!
