There's a lot of contradictory advice
regarding raw foods for dogs. Some people fear that it will make their
dog aggressive and others think they have to feed dry, canned or cooked
food to prevent their dog from getting parasites or dangerous bacteria.
Then there are those that just can't believe their pet is actually a
meat eating carnivore... or is that omnivore? Some people feel that
handling raw food for their pet is just plain repulsive.
Many people never consider exactly what their dog is really eating or
look at the back of the package when they are deciding what to feed
their pet. They may have seen an advertisement on television or in a
magazine that has influenced their choice. Nutritional guidelines for
pet foods have been defined and are displayed on the products but for
the most part this doesn't really tell anyone about the actual quality
of the food itself.
The guaranteed analysis on any pet food label lists the minimum level of
crude protein and fat as well as maximum amounts of water and crude
fibre on a dry matter basis. The analysis does not guarantee the actual
amount of protein, fat, water and fibre. Rather, it indicates legal
minimums of protein and fat and the legal maximums of water and crude
fibre content. Ingredients are usually listed in descending order of
weight but some companies may list them alphabetically or may display an
incomplete ingredient list. No reference to quality of an ingredient is
listed. Therefore, it is difficult to evaluate a product solely on the
basis of the ingredient list.
The statement "complete and balanced" indicates that the product
contains all nutrients presently known to be required and that they are
balanced to the energy density of the diet, but that doesn't mean it's
balanced for a dog's individual needs. Feeding trials must substantiate
the "complete and balanced" claims, or the food must contain at least
the minimum amount of each nutrient recommended according to present
guidelines. That doesn't mean that it actually contains every nutrient
your dog needs to thrive. It merely means the food contains those
nutrients that will keep a dog alive.
Imagine going to the grocery store to shop for your family and every
shelf contains bags of 100% "complete & balanced", processed human food,
guaranteed to meet the nutritional needs of all humans, but you have no
idea what's in the bag. You never get to eat any fresh food, ever. You
eat this food day after day for your entire life.
Dry dog foods, being the top selling convenience product, contain either
'meals' i.e. 'meat meals', 'by-product meals' or 'digests'. The poorest
grade meat comes from animals not fit for human consumption and they are
rendered into meat meal. This rendered product comes from "mammal"
tissues, and does not contain hair, blood, hoof, hide, trimmings,
manure, stomach and rumen contents "except in such amounts as may occur
unavoidably in good processing practices". Meat by-products by
definition, consist of the non-rendered, clean parts, other than meat
derived from slaughtered 'mammals'. It includes, but is not limited to
lungs, spleen, kidney, brain, liver, blood, bone, low temperature fatty
tissue, stomachs and intestines without their contents. Digests are
dried material resulting from chemical and/or enzymatic hydrolysis of
clean and un-decomposed animal tissue. The animal tissue used does not
contain remnants of hair, horns, teeth, hooves and feathers, "except in
such trace amounts as might occur unavoidably in good factory practice".
You might be thinking "just a minute, this all sounds like good food for
a carnivore, doesn't it?" While many of these ingredients may be
acceptable foods for a carnivore, the problem is none of these
descriptions ever mention where these food sources come from.
Just about anything unfit for humans or animals finds its way into
rendering plants. This material is then denatured, preventing its return
into the human food chain. Machines grind the material and then it is
cooked at high temperatures. The grease is extracted and becomes a
source of animal fat in many dog foods. These un-stabilized fats undergo
oxidation, become rancid and they also contain high levels of extremely
harmful peroxide-free radicals. Did you know that rancid fat can legally
be used in dog food?
Because conventional dog foods contain fats, a stabilizer is needed to
maintain the quality of the food. Common preservatives include
ethoxyquin, BHA (butylated hydroxyanisole), BHT (butylated
hydroxytoluene) and vitamins E and C. Ethoxyquin was first used as a
rubber stabilizer and an insecticide and pesticide. It is probably one
of the most powerful preservatives available. BHA and BHT are used in
human food as well as dog foods and have a long history of suspected
carcinogenesis. Companies that buy ingredients, such as fat, that have
already been preserved with a chemical like ethoxyquin do not by law
have to list ethoxyquin as an ingredient of the food. Even vitamin E
could have the potential to cause problems as only 'alpha' tocopherol
acts as a preservative. The tocopherols often used in dog foods may be
other types such as gamma, beta and delta. In short, foods containing
these antioxidants have longer shelf lives, but the continued feeding of
them may cause long-term health problems for dogs.
The main ingredient in the majority of dog foods is grains, rather than
meat. If grains are not listed as the first ingredient they are usually
the second or third and more often than not, comprise a good portion of
the protein source in the product. Grains not suitable for human
consumption may be used and can include broken grains, crop and weed
seeds, hulls, chaff, joints, straw, elevator or mill dust, sand and
dirt. Worse yet, they may contain herbicides, fungicides and pesticides.
Dog food manufacturers often manipulate the order of the ingredients
listed in several ways. Grain ingredients are listed as separate
fractions, rather than together as a single grain, in order to increase
the likelihood that the meat ingredients are closer to the top of the
list.
Essential Fatty Acids are virtually non-existent in commercial food as
they are destroyed by heat during manufacturing. Some companies add
essential fatty acids to the food after processing, but they are so
fragile that they become rancid when exposed to light and air. That
means that once the bag of food is opened, the fatty acids are destroyed
and they become dangerous to the dog's health.
Nutrients in food are depleted, destroyed, and altered by cooking or
heat processing. The degree of alteration is only a matter of
temperature, cooking method, and time. High temperatures create
cross-links in protein. Cross-linked proteins are implicated as a factor
in the acceleration of the aging process as toxic substances and
"by-products" are created. The higher the cooking temperature, the more
toxins are created. Studies have concluded that cooking meat at high
temperatures, to the well-done stage, produces chemicals called
heterocyclic amines (HCAs) that can cause mutations (genetic damage) to
cells, a first step in cancer.
Most, if not all enzymes present in raw foods are destroyed at
temperatures as low as 117 degrees Fahrenheit. Digestion of cooked food
is much more energetically demanding than the digestion of raw food. In
general, raw food is so much more easily digested that it passes through
the digestive tract in half to a third of the time it takes for cooked
food to digest. Beneficial intestinal flora becomes dominated by
bacteria, particularly from cooked meat, which may result in intestinal
dysfunction, allowing the absorption of toxins from the bowel. This
phenomenon is called dysbiosis, or intestinal toxemia.
As cooked animal foods are generally lower in nutrient value, individual
cells in a dog's body may not receive enough of the nutrients they need.
The immune system, having to handle the daily invasion of toxins and
toxic by-products, eventually becomes overwhelmed and weakened. The
wastes, toxins, mutagens, and carcinogens that build up within cells, as
well as the daily onslaught of excess free radicals, may eventually
cause some cells to become cancerous. In other words, cooking food
doesn't make it as healthy or safe as we would like to believe.
