Dog Food Ingredients
    Everything you ever wanted to know about what's in your dog food...

    If you're curious about what makes up your dog's food, these are all commonly found *premium* dog food ingredients. You should remember, though, that it's equally important to pay attention to what's not in your dog's food: no fillers, no artificial colors, no artificial preservatives and no artificial flavors.

    We have organized the ingredients in alphabetical order. You will find each ingredient, followed by its classification, and then its definition and/or what health benefits it provides.



A

Alpha-linolenic acid
fatty acid
An omega-3 fatty acid which may be an essential fatty acid for your dog.

Amino Acids
amino acid
Amino acids are smaller subunits of protein or protein building blocks. There are about 20 amino acids, and they can be arranged in almost infinite sequences, resulting in a wide variety of proteins. These are found in hair, skin, muscle, antibodies, enzymes and hormones. Lack of amino acids in the proper amounts, causing protein chains to be incomplete or interrupted, leads to health problems. When amino acids are not produced or consumed in the proper amounts, the body may continue to "run" but the animal will develop symptoms of poor health from the loss of continuous protein turnover. Meat proteins contain all the essential amino acids, in at least the minimum amounts required, to best supply your dog's needs.

Arachidonic Acid
fatty acid
An omega-6 polyunsaturated acid found only in animal fats. Arachidonic and linoleic acid are essential fatty acids for cats. Dogs only require linoleic acid, but some Arachidonic Acid in their diet certainly won't hurt.

Ascorbic Acid
vitamin
A dietary source of vitamin C.

B

Beef By-Products
protein
Beef by-products are a protein source that includes beef muscle meat as well as beef organ meat. They provide essential amino acids for muscle building, tissue repair, hormone synthesis and other metabolic processes.

Beef Heart
protein
Whole, trimmed, boneless heart from beef. It provides essential amino acids for muscle building, tissue repair, hormone synthesis and other metabolic processes.

Beef Liver
protein
Whole or ground liver from beef. It provides essential amino acids for muscle building, tissue repair, hormone synthesis and other metabolic processes.

Beet Pulp
fiber
Beet pulp is the material which remains after sugar is extracted from sugar beets. Therefore, beet pulp contains little or no sugar. Beet pulp is a source of fiber in dog and cat diets. It is a moderately fermentable fiber, and provides bulk for normal feces and energy for cells lining the intestine. It also enhances intestinal health and is broken down by intestinal bacteria to provide short-chain fatty acids, an energy source for intestinal cells. There is nothing in beet pulp that can affect coat pigment, because the inside of the beet is light in color. The outside peel, which is dark, is not used.

Beta-Carotene
vitamin
A naturally occurring compound found in many foods that can be converted by the liver to vitamin A. It is present in plants. It optimizes different types of cells present in the blood, increases antibody levels in the blood, and optimizes vaccine recognition by dogs.

Biotin
vitamin
A water-soluble B vitamin, important for formation of fatty acids, nonessential amino acids, and production of energy from glucose metabolism.

Brewers Dried Yeast
vitamin, protein
The dried non-fermentative, non-extracted yeast of the botanical classification saccharomyces or candida, resulting as a by-product from the brewing of beer and ale. It does not contain or produce alcohol. It is a source of protein and B vitamins. It is used to promote a healthy coat and assists with vitamin availability.

Research has shown that cellulose, in combination with beet pulp, improved the efficiency of hair movement through the digestive tract of cats. As with any fiber, cellulose cannot be broken down/digested by the intestinal enzymes of the dog or cat.
