All Natural Dog Food
Commercial dog food is a great convenience for busy caregivers. You want the
best for your companion animals, but with a bewildering array of foods and
claims to choose from, how do you decide whats best for your animals?
Standards For Dog Food Ingredients
The commercial dog food industry is huge and extremely profitable ($25 billion a year in revenue worldwide). While manufacturers may appear to have the best interests of your companion animals at heart, they are generally more concerned about their stock prices and bottom lines. This may be especially true of commercial dog food manufacturers owned by large, diverse, multinational parent companies. What this means to you is that if an inexpensive ingredient is available to replace a costlier one, many companies will make the substitution to save money. A few companies pride themselves on their fixed formulas, meaning that they always use the same ingredients. This may be good ... if the ingredients are of acceptable quality to begin with.
Dog food may be labeled as "complete and balanced" if it meets the standards set
by a group called AAFCO, the Association of American Feed Control Officials.
These standards were formulated in the early 1990s by panels of canine and
feline nutrition experts. A food may be certified in two ways: (1) by meeting
AAFCOs published standards for content (Nutrient Profiles), or (2) by passing
feeding tests or trials. While most researchers agree that feeding tests are
superior in assessing the nutritional adequacy of a food, clinical experience as
well as scientific studies have confirmed that even foods that pass feeding
trials may still be inadequate for long-term maintenance. Also keep in mind that
the standards set only minimums and maximums, not optimums. Commercial
foods are designed to be adequate for the average animal, but not all foods will
be suitable for an individual animals variable needs.
Commercial Dog Food Problems
Commercial dog foods and some dog food ingredients have been implicated in a number of diseases in companion animals. Allergic skin disease, obesity, food intolerance, inflammatory bowel disease, chronic ear infections, cystitis (bladder inflammation), bladder and kidney stones, certain heart diseases, pancreatitis, feline hyperthyroidism, hip dysplasia, canine mammary cancer, bloat, and diabetes all have nutritional components that is, nutritional factors are suspected or known to play a role in inducing or perpetuating these diseases. Thus, it is crucial that we, as caregivers, pay close attention to what we are feeding our animals and how they are reacting to the food.
One potential problem with commercial dog food is pesticide residues, antibiotics, and molds contained in dog food ingredients. Meat from sick animals may be loaded with drugs, some of which are known to pass unchanged through all the processing done to create a finished dog food (such as penicillin and pentobarbital). Between 1995 and 1999, there were two major recalls of dry commercial dog food by different manufacturers due to mold contamination of grain ingredients. Some fungal toxins are very dangerous. The second recalled food killed more than 20 dogs.
Another problem is the unpredictable quality of common commercial dog food ingredients. By-products, by-product meal, meat and bone meal, and similar ingredients can vary widely in their nutrient composition. Bone meals in the U.S. have had a lead contamination problem for many years. The protein in a meal containing a large amount of bone may be poorly digestible and fail to provide adequate nutrition, even though chemical analysis will reveal an acceptable amount of amino acids.
One of the biggest problems with commercial foods is the processing they undergo. Meals are rendered (cooked) at moderate to high temperatures for hours. Extruded foods pass through a steam heat/high pressure device that allows them to "puff" into kibble shapes when they come out of the machine. Even though they move through the extruder quickly, the extreme conditions may alter or damage some nutrients.
Commercial dog food manufacturers are aware of these factors, and most add sufficient extra vitamins, minerals and other nutrients to compensate for losses in the manufacturing process. However, because the AAFCO profiles set only minimums for many nutrients, tests have shown that some minerals may be added to the food in excessive amounts.
Dog Food Label "Rules"
- The 95% Rule: If the product says Salmon Cat Food or Beef Dog Food, 95% of the product must be the named ingredients. A product with a combination label, such as Beef and Liver for Dogs, must contain 95% beef and liver, and there must be more beef than liver, since beef is named first.
- The 25% or Dinner Rule: Ingredients named on the label must comprise at least 25% of the product but less than 95%, when there is a qualifying descriptor term like dinner, entree, formula, platter, nuggets, etc. In Beef Dinner for Dogs, beef may or may not be the primary ingredient. If two ingredients are named (Beef and Turkey Dinner for Dogs), the two ingredients must total 25%, there must be more of the first ingredient (beef) than the second (turkey), and there must be at least 3% of the lesser ingredient.
- The 3% or With Rule: A product may be labeled Cat Food with Salmon
if it contains at least 3% of the named ingredient.
The Flavor Rule: A food may be labeled Turkey Flavor Cat Food even if the food does not contain such ingredients, as long as there is a sufficiently detectable amount of flavor. This may be derived from meals, by-products, or digests of various parts from the animal species indicated on the label.
