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

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
Digestibility
So 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

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.
