Read this carefully because some people HERE have posted about
meals, and they are totally wrong. It's sad when people post about something they know so little about.
Ingredient groups - what to look for and what to avoid
Protein
Protein, in the form of quality meat ingredients, is the most important component of a dog's diet. As animals with a carnivorous background, their digestive tract is designed to utilize primarily meat and fat. It is also the most expensive ingredient for a manufacturer to buy and the profit margin on a product is drastically affected by the amount and quality used. Ideally, the first ingredient of a food should be either a specified meat meal, or a specified fresh meat type followed by a meal. If your individual dog's specific needs limit you to using foods that do not include a concentrated source of meat in meal form, I highly recommend supplementing with fresh or canned meats on a daily basis.
* Generically named sources of protein or fat (animal ___, meat ___, poultry ___, etc.) are never present in truly high quality products because they are derived from highly questionable sources. If a manufacturer uses quality ingredients and has nothing to hide, there is no need for generic names.
* Byproducts of any type are less desirable and only acceptable if they do not make up the main source of animal protein and if the name of the species used is also defined in some manner (e.g. "chicken byproducts" or "beef byproducts" but not "meat byproducts" or "poultry byproducts"). Byproducts consist of anything but the quality cuts of meat and highest quality edible offal used for human consumption. What this means (on a market with high demand for human snacks like "buffalo wings" and cheaper pet foods requiring flavoring agents like beef or chicken liver digest to make otherwise uninteresting food more attractive), I leave to your imagination.
* Contrary to what many people believe, meat sources in "meal" form (as long as they are from a specified type of animal, such as chicken meal, lamb meal, salmon meal etc.) are not inferior to whole, fresh meats. Meals consist of meat and skin, with or without the bones, but exclusive of feathers/hair, heads, feet, horns, entrails etc. and have the proper calcium/phosphorus ratio required for a balanced diet. They have had most of the moisture removed, but meats in their original, "wet" form still contain up to 75% water. Once the food reaches its final moisture content of about 9-12%, the meat will have shrunk to sometimes as little as 1/4 of the original amount, while the already dehydrated meal form remains the same and you get more concentrated protein per pound of finished product. This means that in the worst case you are left with only 4 ounces of actual meat content per pound of fresh meat included in a dry kibble, many of which contain less than one pound of meat per 2-3 pounds of grain to begin with. Preferably a food contains quality meat meal as well as some fresh meat.
