We have to
start this page with a heartfelt thanks to Mr. Earl
Wolfe. Mr. Wolfe has put together a web page called:
UNDERSTANDING DOG FOODS AND DOG FOOD LABELS
We have spent quite a bit of time
researching pet foods and their nutritional
values. In the process of researching dog food
online, we found Mr. Wolfe's website. We feel safe to
say that there is more information compiled on his website
than we have found anywhere else. He has graciously
allowed us to put this information on our site and we thank
him for it. There is additional information
on his website, including very in depth, brand by brand,
analysis and comparisons. You can reach his site through
the above link.
Every dog food label must
include specific information, which is usually divided into two
parts:
-
Principal Display
Panel
-
Information
Panels
Let's start with the
Principal Display Panel. This is very straightforward information
like the following: (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.
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--YOU, THE CONSUMER! 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
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.
Much of this information
comes from the AAFCO (Association of Animal Feed Control Officals)
Handbook
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!!

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

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

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.
