A look at Dog food
These types of food materials are different with different grades of liking by the dogs. Dogs like dry foods only if they are tasty only and however, on comparison, the dogs prefer only the canned food items. Reason for such preference by the dogs is that in case of canned food items, the moisture is about seventy to eighty per cent but in case of dry food, it is only about ten per cent.
However, if you view it in terms of nutrients, often the dry food contains nearly ninety per cent nutrients whereas the canned food items contain only less per cent of nutrients and most of the times. It is only soy products that are structured so well to look like meat pieces.
