Dog Food Information

Have you ever wondered whether the label information on your dog's food packaging is accurate? If so, welcome to the club! We fret about this sort of thing, too – and sometimes, our worries turn out to be well-founded.

As soon as a food is manufactured, it begins to undergo a variety of chemical and physical changes. It's a basic law of the universe (the second law of thermodynamics) that everything degrades over time. This includes the proteins and vitamins in dog foods, but it's the fats I worry about the most.

Fungus is more than a nuisance when it comes to corn; it can be deadly to dogs (and humans). Actually, it’s not fungus itself that’s a problem; the peril is a secondary chemical product created by the metabolic process of certain fungal species, in particular, Aspergillus flavus and Aspergillus parasiticus. Aflatoxin, the chemical produced by these fungi is not just toxic, it’s one of the most carcinogenic substances known to science.

Fish oil is probably the most important supplement you can add to your dog's diet, regardless of what type of diet you feed. EPA and DHA, the omega-3 fatty acids in fish oil, provide widespread benefits, but they are fragile and unlikely to survive storage in bags of kibble, or may be rancid even before being added to pet foods. Krill oil and whole fish also provide EPA and DHA that may be better absorbed, providing similar benefits in smaller doses.

It is not easy to figure out how much fat and other nutrients are really in the food you feed, whether it's kibble, canned food, or a home-prepared raw or cooked diet. Here are some tips that can help. There are three different ways of measuring amounts of protein, fat, carbohydrates, and fiber in foods.

All pets cared for by Hill’s Pet Nutrition live in a loving, safe, playful, and clean environment. We use only non-invasive, humane research methods. Hill’s does not participate in studies that jeopardize the health of dogs and cats. No study that requires euthanasia will be performed on dogs or cats. When studying how a nutrient is absorbed, distributed, stored, used and released by a dog’s or cat’s body, we use only research methods that are the veterinary equivalent of human nutritional or medical studies. Hill’s does not support or conduct studies that cause pain or hurt the dogs or cats. This is based on the belief that what is painful to humans is also painful to dogs and cats.

In recent years, the pet food industry has discovered the benefit of sharing more information about its products, manufacturing and research and development with consumers. In a highly competitive market, it's advantageous to project a confident image of full transparency - as long as the company is doing everything they say they are doing. In the wake of a substantial amount of bad PR from a nearly decade-old PETA campaign showing conditions of research animals, Whole Dog Journal had the opportunity to conduct extensive tours of two large pet food manufacturers' research facilities.

On March 30, the U.S. Food and Drug Administration announced that it had rejected a petition from environmentalists that would have banned bisphenol A (BPA) from all food and drink packaging. The scientific evidence at this time, said the FDA, does not suggest that the “very low levels of human exposure to BPA” afforded through our diets are unsafe. “The agency has performed extensive research on BPA, has reviewed hundreds of other studies, and is continuing to address questions and potential concerns raised by certain studies,” the news release continued. “The agency takes all concerns about BPA seriously and is evaluating them as part of the agency’s ongoing oversight of food safety.”

With your dog sitting at your side, hold her food bowl at chest level, and tell her to “wait.” Move the bowl (with food it in, topped with tasty treats) toward the floor 4 to 6 inches. If your dog stays sitting, click your clicker and feed her a treat from the bowl. If your dog gets up, say “Oops!” and ask her to sit again. If she remains sitting, lower the bowl 4 to 6 inches again, click and treat.

Dog food manufacturers are supposed to list specific names for each ingredient in their formulations. Each food, vitamin, mineral, or other chemical (preservative, color, flavor, binder, etc.) that has been approved for use in a dog food is supposed to be listed in a certain way on the product’s ingredient list. There are formal descriptions of each ingredient – and all of these are listed in the annual “Official Publication of the Association of American Feed Control Officials (AAFCO)”.

When I compared a nutritional analysis of Preference plus turkey to the 2006 National Research Council (NRC) nutrient recommendations, the minerals zinc, copper, and selenium, vitamins D and E, and possibly some B vitamins were all low. This is because commercial dog foods are designed to meet nutrient profiles established by the Association of American Feed Control Officials (AAF CO), whichare based on older research published by the NRC in 1985.

Deborah Allen, of Boise, Idaho, feeds a dog food diet that combines a commercial pre-mix with raw ground turkey to her two Labrador Retrievers: Hartford, a highly active, 6-year-old working guide dog who weighs 76 pounds; and Lily, a moderately active, 14-year-old retired guide dog who weighs 53 pounds. Their veterinarian says both dogs are healthy, but they have begun losing weight and developing skin problems in the last few months. Hartford is about 4 pounds and Lily about two pounds under their ideal weights.
