Understanding Dog Foods and Dog Food Labels
DISSECTING THE FOOD LABEL
Much of the information on this page comes from the book "The Consumer's
Guide to Dog Food: What's in Dog Food, Why It's there and How to Choose the Best
Food For Your Dog" By Liz Palika You can purchase "The Consumers Guide
to Dog Food" from amazon.com Reprinted with permission
Every dog food label must include specific information, which is usually
divided into two parts:
- 1. Principal Display Panel
- 2. Information Panels
Let's start with the Principal Display Panel. This is very straightforward
information like the following:
- 1. Brand Name (i.e., Iams, Purina, Kal-Kan, etc.)
- 2. Identity Statement which describes the contents of the food (i.e.,
Chicken Rice, Mushroom and Gravy, etc.)
- 3. Designator of what class the food is (i.e., Growth, Maintenance, Lite,
etc.) and Category of dog (Puppy, Adult, Senior, etc.).
- 4. Quantity of contents identifies the weight of contents (i.e., 5 pounds,
20 pounds, 40 pounds)
In summary, the Principal Display Panel is like the name of your town. It
identifies where you are, but it doesn't tell you how to get around. For a road
map of the food, you need to get able to read the stuff on the Information
Panel.
Now let's talk about the Information Panel. This tells you about the actual
food content.
- 1. General analysis (shows the "as is" percentages of the food's
constituents).
- 2. Ingredients list (shows ingredients in descending order, by weight).
- 3. Nutritional adequacy claim (identifies specific life stage for which
food is intended and whether animal feeding tests based on AAFCO procedures
were used).
- 4. Feeding instructions (how much of the food to give your dog).
GUARANTEED ANALYSIS
The Guaranteed Analysis on the Information Panel of the dog food label lists
the minimum levels of crude protein and fat and the maximum levels of fiber and
water. "Crude" refers to the total protein content, not necessarily the amount
of protein that is actually digestible. What this means is that this is ONLY a
crude protein percentage, and fat amounts are rough guides. The actual amounts
depend upon the ingredients and their quality.
The amount of moisture in a food is important, especially when you are
comparing foods. A food containing 24% protein and 10% moisture would have the
same protein per serving than a food with 24% protein listed on the label but
only 6% moisture. The thing to consider here is that your are buying water
instead of food. This is why it is important to consider the saturation point of
the moisture.
The AAFCO guidelines are formulated on a dry matter basis, so that all foods
can be compared equally. can be compared equally.
Guaranteed analysis:- is only a very small part of the nutritional
picture. It is also important to note that Phosphorus is directly related
to the exacerbation of Renal Disease. Renal Disease is the #1 cause of death in
dogs!
INGREDIENTS LIST
Ingredients are listed in descending order, by weight. However, the listings
may be misleading. Suppose beef is listed as the first ingredient, causing you
to think it is the primary ingredient. Look again. If it's followed by wheat
flour, wheat germ, wheat middlings and so on, the combined wheat products may
very well total much more than the beef.
ARTIFICIAL COLORING
Many of the artificial colorings used in dog foods have been associated with
potential problems. FD&C red No. 40 is a possible carcinogen but is widely
used to keep meat looking fresh. Blue No. 2 is thought to increase dogs'
sensitivity to viruses. Another color that is commonly used but has not been
fully tested is Yellow No. 5. Both Red No. 2 and Violet No. 1 were banned by the
FDA in the mid-seventies as possible carcinogens but prior to that were widely
used in pet foods.
Interesting as it may sound, the food color used in today's manufacture of
foods is not for the dogs. It is to satisfy the dog's owner--
There's More!
Sugar: is not an ingredient most people
would expect to find in dog food, but many foods do, in fact, contain sugar,
especially the semi-moist brands. In fact, some semi-moist foods contain as much
as 15% sugar. The sugar adds palatability and moisture, and aids in bacterial
contamination prevention. Dogs do not need this amount of sugar, which can
stress the pancreas and adrenal glands, causing diabetes. Completely devoid of
protein, vitamins and minerals, sugar is, literally, empty calories.
Salt: is added to many foods as a meat
preservative. Too much salt can irritate the digestive system and can cause a
mineral imbalance because the salt itself can upset the calcium / potassium
balance in your dog's system. Too much salt can be life threatening for a
dog.
REMEMBER QUALITY
The presence of some or all of the ingredients which are the most commonly
used dog food ingredients, or an assortment of these ingredients, doesn't
necessarily mean that your dog is going to be well nourished. The ingredients
must be in the right combinations and of good quality--both before and after
processing.
Biological Value - The biological values of
the ingredients are a key to good nutrition. The biological value of a food is
the measurement of the amino acid completeness of the proteins contained by the
food. Eggs are considered a wonderful source of protein because they contain all
of the essential amino acids.
| BIOLOGICAL VALUE |
| Eggs |
100% |
| Fish Meal |
92% |
Beef Chicken Lamb Other Meat's |
78% |
| Milk |
78% |
| Wheat |
69% |
| Wheat Gluten |
40% |
| Corn |
54% |
Neither wheat nor corn would be an adequate diet alone, but fed together with
one or two meat-based proteins capable of supplying the missing amino acids,
they could supply an adequate diet.
According to the definition in the 27th edition of "Dorland's Medical
Dictionary" "Nutrition" is "the sum of processes involved in taking in
nutrients and assimilating and utilizing them".
Nutrients are (Fat, Protein, Carbohydrates, Vitamins, Minerals, and
Water) necessary for the growth, normal functioning and Maintaining of life.
The two main points are:
Palatability
DigestibilitySo ingredients are only as important as the nutrients
contain, how good they taste to the pet, and their digestibility.
Think of ingredients as a big truck and nutrients as produce the truck's
carrying. If the truck is trying to go into a tunnel, but it won't fit ( not
digestible), it's not going to be able to drop off its load, This would be a
poor ingredient to put into a food.
If the truck goes through the tunnel, but only has lettuce in the bed when it
could have fit valuable tomatoes, potatoes and onions, then it wasn't a very
efficient load. This would be an example of how one pet food manage nutrients
within one ingredient (truck).
If the truck isn't allowed into the tunnel because the person at the toll
booth doesn't lie the drive, then it's all in vain. the ruck could have the best
produce in the world, but it can't get in. This is an example of a dog or cat
rejecting the food (palatability).
Digestibility of Food - Digestibility
refers to the quantity of the food that is actually absorbed by the dog's
system. This can be obtained by contacting the manufacture directly. If your
selected manufacture does not have this information you can calculate it
yourself. This is how you can figure it out. Weigh the amount of food that you
feed and the weight of the stool for several days. Divide the weight of the food
into the weight of the stool and you will have the percentage of digestibility.
It is important to note here that the stool that you are going to use MUST be
dried to the same moisture content as the food you feed if you want to be close.
You will also need a little more math than just add, subtract, divide and
multiply if you want to be close to an accurate answer. The more food fully
metabolized, the higher the digestibility figure.
Quality Before Processing - Understanding
the definition of an ingredient is not enough. Many grains grown in poor soil
will lack needed vitamins and minerals, and, unfortunately, this is a common
occurrence in the United States. Grains and vegetables can be polluted with
fertilizer residues and pesticides of various kinds.
Ingredients can also be soiled with mold, mildew, and fungus. The quality of
meat can also be suspect. We have all heard stories or had personal experiences
of finding bits of hair and other unsavory additives in our hamburger, but the
quality of meats used for dog foods is much lower. The U.S. Department of
Agriculture (USDA) has said that there is non-mandatory federal inspection of
ingredients used in pet food manufacturing.
However, some states do inspect manufacturing plants, especially those
producing canned pet foods. In the majority of states it is legal (and common
practice) for pet food manufactures to use what are known as "4-D" meat
sources--animals that are dead, dying, diseased, or disabled when they arrive at
the slaughterhouse. Dr. P. F. McGargle, a Veterinarian and a former federal meat
inspector, believes that feeding slaughterhouse wastes to pet animals increases
their chances of getting cancer and other degenerative diseases. He said, "Those
wastes include moldy, rancid or spoiled processed meats, as well as tissues too
severely riddled with cancer to be eaten by people." In Summary - Dog food labels do contain a lot of
information, and learning how to decipher them can take some time. However, the
time to do that is not when you're in the aisle looking at all the foods
available. Instead, study the labels at home so that you can look at them more
thoroughly. Most dog food manufacturers provide pet stores and Veterinarians
with boxes of dog food samples. These are yours for the asking. If you get a
variety of samples from different companies, you can then study those labels at
home, at your leisure.
As you study, keep in mind that there is also a lot of information not freely
given on the label such as the quality of the ingredients used. As we know, that
information can be difficult to come by and you may need to rely upon the
recommendation of experts, including your Veterinarian. You have to consider the
price, quality, and reputation of the manufacturer. Also remember that at the
present time NO pet food manufacture makes a "Breed
Specific" pet food.
More on DISSECTING THE FOOD LABEL - PART II
Some of this information came off the dog food bags, cans, etc. No one
company or distributor has compiled or produced a chart that I know of which
compares the major brands of dog foods at this time and has made it
FREE for you to use.
These charts are meant to give you some idea as to what goes into the food
we feed our pets. These charts are
NOT meant to tell you what to buy or feed your pet. Their
purpose is to show you what goes into dog food, and that is all. Only you can
determine what to feed your pet!!
DOG FOOD INGREDIENTS (These are the terms used in the Dog Food
Comparison Charts)
Grains
Amaranth - Is considered to be the father to
all grains that are currently grown. It is considered to be a superior
source of carbohydraes, minerals and rich flavor
Corn Gluten Meal - The by-product after the
manufacture of corn syrup or starch which is the dried residue after the
removal of the bran, germ, and starch.
Alfalfa Meal - The finely ground product of
the alfalfa plant.
Semolina - The endosperm of durum wheat is
called semolina, high protein used in fine pasta.
Barley - At least 80% good quality barley; no
more than 3% heat damaged kernels, 6 percent foreign material, 20% other
grains or 10% wild oats.
Barley Flour - The soft finely ground barley
meal obtained from the milling of barley.
Ground Corn (also called Corn Meal or Corn
Chop) - The entire corn kernel ground or chopped. It must contain no
more than 4% foreign material.
Brewer's Rice - The small fragments of rice
kernels that have been separated from larger kernels of milled rice.
Brown Rice - The unpolished rice left over
after the kernels have been removed.
Soybean Meal - By-product of the production
of soybean oil.
Grain Sorghum - Sorghum is a member of the
Grass family. There are many different varieties. They can be clasified into
4 groups.
- Grain Sorghums
- Grass Sorghums
- Sweet Sorghums
- Broomcorn
- Broomcorn is grown for the brush or brances of the seed cluster. The
fibers are used in the manufacture of brooms.
- Sweet Sorghums of sorgos, have a sweet juicy stem. These are used to
produce sorghum syrup. Animal Feeds and silage can also be made for the
sweet sorghums.
- Grass Sorghums are grown for green feed and hay but can be found in
Kansas fields of weeds. Two types are Sudan and Johnson grass.
- Grain Sorghums are grown especially for the rounded, starchy seeds.
The grain Serves as A substitue for corn in feeding animals. Some grain
sorghums grow as much as 15 feet high. The entire plant can be used to
make silage. World wide, common grain sorghums include milo, durra and
kafir.
Ground Grain Sorghum - Made by grinding
grains of sorghum.
Cereal Food Fines - The by-product of
breakfast cereal production which consists of particles of the foods.
Flaxseed - Is also known as Linseed. It is
very high in Omega-3 fatty acids. Once a container of this is open it will
spoil rapidly. It is best to keep it under refrigeration.
Linseed Meal - The residue of flaxseed oil
production, ground into a meal.
Mesquite Bean Meal- This is full of essential
nutrients, helps regulate blood sugar, and is an excellent source of
carbohydrates.
Oatmeal - Is a heart smart food that is an
excellent fiber source and is clinically proven to lower cholesterol.
Meats and Meat
by-Products
Meat or Meat Based - Meat is the clean flesh
of slaughtered cattle, swine, sheep or goats. The flesh can include striated
skeletal muscle, tongue, diaphragm, heskeletal muscle, tongue, diaphragm,
heart or esophagus, overlying fat, and the portions of skin, sinew, nerves,
and blood vessels normally found with that flesh. This is what some people
would call on the hoof or "wet - state". This applies equal to all livestock
whether it be Beef, Chicken, Lamb, etc.,,,. After processing these meats can
loose up to 80% of their weight. Thus when looking at the ingredients list
you might find it as number one but in truly reality after processing it
will fall between 4, 5 or even 6 on a ture ingredients list.
Meat Meal - Rendered meal made from animal
tissue. It cannot contain hair, hoof, blood, horn, hide trimmings, stomach
or rumen (the first stomach) contents, or manure except for amounts that may
not be avoided during processing. It cannot contain any added foreimay not
be avoided during processing. It cannot contain any added foreign matter and
may not contain more than 14% indigestible materials. Indigestible crude
protein in the meal cannot be more than 11%. Meals are also use after
processing and give a more ture actual weight on the list of ingredients for
placement over whole meats or "wet - state" meats.
Meat By-Product - Clean parts of slaughtered
animals, not including meat. These parts include lungs, kidneys, brain,
spleen, liver, bone, blood, partially defatted low-temperature fatty tissue,
stomach, and intestines freed of their contents. It does not include hair,
teeth, hooves or horns. Only 14% may be indigestible residue and no more
than 11% indigestible crude protein.
Chicken Liver - Organic meat , highly usable
protein source containing vitamins A , K and Foliate. It also contains
minerals Phosphorus and potassium. Many Amino Acids are also found in
Chicken Liver.
Poultry By-Product - Clean parts of
slaughtered poultry, such as heart, lungs, liver, kidneys, feet, abdomen,
intestines, and heads and must not contain feces or foreign matter except
that which is unavoidable and then only in trace amounts.
Poultry By-Product Meal - Made up of ground,
rendered, and clean parts of slaughtered poultry, such as undeveloped eggs,
necks, feet, and intestines. It does not contain feathers except those which
are unavoidable during processing.
Dehydrated Eggs - Whole poultry eggs which
are dried.
Meat and Bone Meal - Rendered from meat and
bone, but it does not include hair, blood, horn, hoof, manure, hide
trimmings, stomach, or rumen contents except that which is unavoidable
during processing. It does not include any foreign matter. Like meat meal,
only 14% may be indigestible residue and no more than 11% indigestible crude
protein.
Whole Fresh eggs - This is the Highest rated
source of usable Protein, and rates above all meats and meat products.
Shells are a great source of Calcium Carbonate good for strong healthy
teeth.
Beef Tallow - This is the Very Hard white
fatty substance which is rock hard and looks like a bone. Most dogs have
great difficulty in digesting this substance.
Animal By-Product Meal - Consists of rendered
animal tissue which does not fit in any of the other categories. It cannot
contain hoof, hide trimmings, extra hair, horn, stomach or rumen contents,
manure or any foreign matter.
Animal Digest - A powder or liquid made by
taking clean under-composed animal tissue and breaking it down using
chemical and or emblematic hydrolysis. It does not contain horn, teeth,
hair, hooves, or feathers except in trace amounts which are unavoidable,
Digest names must be descriptive of their contents....that is, chicken
digest must be made from chicken and beef digest made from beef.
Fish Meal - Clean, dried, and ground tissue
of undecomposed whole fish or fish cuttings which may or may not have the
oil removed. It is also considered an excelent source for Omega 3 fatty
acids.
Salmon - Excellent source of protein and
fatty acids like Omega-3 and Omega-6.
Fruits and
Veggies
Turnip Greens - Contains some calcium,
Omega-3 and vitamin A & C.
Tomatoes - Abundant in carotenoids,
beta-carotene, and vitamins A & C. They are also an acidifier and a
fiber source.
Peas and Carrots - Are used as an excellent
source of vitamins and minerals they also provide a flavor that both dogs
and cats love.
Oranges - Contain the pure Vitamin C
(Ascorbic Acid) good for immune support, reduces cholesterol, powerful
anti-cancer tool. A natural preservative and a digestive cleanser, The peel
contains oils that stimulate the immune system ( used in cancer
treatment.)
Grapefruit - Has calcium, high in vitamin C
& A, magnesium, phosphorus, vitamin K, carbohydrates, and increases the
effectiveness of nutrient absorption and potency of other fruits and
vegetables when combined. It acts as a preservative and lowers cholesterol.
Combines with orange to form and effective cancer fighting tool.
Beet Pulp - The dried residue from production
of sugar from sugar beets.
Misc
Biotin - Vitamin essential to cellular
metabolism, it helps metabolize fats, carbohydrates and proteins. Biotin
prevents anemia, muscular pain, and skin disorders. It also helps prevent
heart disease. Is a concentrated, non-processed natural food source of
active enzymes, probiotics cultures, amino acids, vitamins, minerals, fatty
acids and various other micronutrient.
Dried Whey - The thin part of milk separated
from the curd, or thicker part, when milk coagulates. Dried whey is this
milk part, dried, and is not less than 11% protein or less than 61% other
grains or 10% wild oats.
Probiotics and Probiotics - This is the
natural micro-flora like enzymes and friendly bacteria that help in the
digestive process. They provide for more efficient utilization of food. It
is important to note that they are also heat sensitive.
Peanut Hulls - The outer hull of the peanut
shell.
Dried Kelp or Dried Seaweed - The maximum
percentage of salt and minimum percentage of potassium and iodine must be
declared.
Ginkgo Biloba - This is a rejuvenating herb
that helps with memoryh and mental functions of older animals by increasing
blood flow to the brain. It is also believed to help improve hearing and
equilibrium.
Glucosamine - This is made up of sugars
(glucose) and amino acids (glutamine). It is the general believed that it
also help in the treatment of osteoarthritis by helping to develop health
bones and cartilage.
Fossil Mineral Flour - Finely ground Coral
and Fossilized rock. These tiny crystals are eaten by parasites in the
intestinal tract and lead to their expulsion from the body. It is one of
natures ways of eliminating parasites. Another is Garlic
Lecithin - A Rich Nutrient that lowers Blood
Cholesterol levels. It is believed to that it strengthens arteries thus
controlling blood pressure. It also helps to reduce the fat content within
arterial walls.
Blue-Green Algae - Humectant, Omega-3 and 6
fatty acids, High in B-12, all essential amino acids, sulfonolipids and
glycolipids, diverse spectrum of vitamins, contains a 95% usable protein
complex, 17 bata-carotenoids, thousands of enzymes, and a vast mineral
array.
Olive Oil - Is monounsaturated, one of the
finest sources of fat and lowers blood cholesterol especially the most
harmful variety. The useful fat in olive oil helps carry important vitamins
through your pet's body like A, D, E and K.
Apple Cider Vinegar - Contains
cholesterol-reducing pectin and the perfect balance of 19 minerals. It
contains 93 different components that can help regulate blood pressure,
fight off infections, relieve arthritis pains, promote healthy digestion,
and improve metabolism. Cleans out toxins from tissues and joints.
Shark Cartilage - This is an excellent source
of Calcium and it is also believed that it will help strengthen bones and
prevent osteoarthritis.
Sodium Bentonite - Sodium Bentonite is
basicly a small amount of inert clay which is used as a binder to aid in the
formulation of small pellets of food. Side advantage of this ingredient is
that it is said to aid in the digestive process.
PRESERVATIVES (These terms are also used in the Dog Food Comparison
Charts)
Brine - Is a pickling solution. Poured off
after pickling leaving only a minimal salt residue.
Brown Sugar - Used as a pickling agent,
moisture stabilizer, and a source of minerals.
Calcium Propionate -This chemical has been
around for a long time.
BHA and BHT - These are both preservatives.
BHA is butylated hydroxyanisole. BHT is butyhlated hydroxytoluene. Both BHA
and BHT have been associated with liver damage, fetal abnormalities, and
metabolic stress. They also have a questionable relationship to cancer.
Ethoxyquin - This preservative has been the
most highly debated item in dog foods for the last several years. It is a
chemical preservative that has been widely used to prevent spoilage in dog
foods and some human foods as well. It is alleged that ethoxyquin has caused
cancer, liver, kidney and thyroid dysfunctions, reproductive failure, and
more, although the allegations have not been proven in tests to date, it is
highly suspect.
Potassium Sorbate - This chemical has been
around for a long time.
Propylene Glycol - This chemical preservative
was designed for use in antifreeze, oil and waxes. It causes irregularities
in the red blood cells of cats. Dogs and Cats can become addicted to it. It
can cause skin problems, hair loss, dull coat, diarrhea, overweight and even
death in both dogs and cats.
Sodium Nitrate - Used both as a food coloring
(RED) and as a preservative. When used as a preservative, it produces
carcinogenic substances called nitrosamines.
NOTE: Accidental ingestion of sodium nitrate by people can be
fatal.
Tocopherols (Vitamins C and E) - Naturally
occurring compounds used as natural preservatives. Tocopherols function as
antioxidants, preventing the oxidation of fatty acids, vitamins, and some
other nutrients. These are being used more frequently as preservatives, as
many dog owners are more concerned about chemical preservatives. Tocopherols
have a very short shelf life, especially once the bag of food has been
opened.
