The Good, The Bad, and The Ugly

The Good

Lamb Meal: An excellent source of protein. It is great for muscle development and overall body maintenance.
Poultry Meal: A good source of protein and fat that provides the essential energy component, and provides the fresh meaty flavor that dogs love. It also promotes muscle, tissue, bone and teeth development.
Poultry Fat: Makes pet food highly palatable. Poultry Fat is high in Omega 6 (3.4%) and other essential fatty acids needed to develop a healthy skin and shiny coat. It also provides energy, and acts as an antioxidant.
Rice: Dogs and cats can almost completely absorb carbohydrates in white or brown rice.
Oatmeal: Supplies carbohydrates and amino acids, and is a good source of fiber. It is also high in iron.
Vitamin A: A source of Preservatives.
Vitamin D: Helps in the absorption of the calcium.
Vitamin E: Helps to maintain a dog's healthy immune system. As dogs age, antioxidants like Vitamin E can help reverse the age-related decrease in immune responses.
Rosemary Extract: A natural antioxidant.
Thiamine Mononitrate: A good source of Vitamin B.
Calcium Pantothenate: An enzyme for energy metabolism.
Riboflavin: Promotes growth and good metabolism.
Niacin: A form of Vitamin B that helps in digestion.
Vitamin B12: A source of enzymes that aid in proper growth.
Biotin: Strengthens the claws and keeps them from chipping and cracking.
Sodium Selenite: A source of selenium that acts as a biological antioxidant.
Folic Acid: Provides the Vitamin B that helps to develop strong claws.
Flaxseed: An excellent source of Omega-3 (0.5%) essential fatty acids, which help to keep the skin and coat in tip-top shape, and maintain lower cholesterol levels.
Dried Whole Egg: High in protein with superior bioavailability.
Potassium Chloride: Plays a vital role in the osmotic balance between cells and body fluids. It is the water balance in the body.
Choline Chloride: Enhances digestive system in the stomach.

The Bad

Corn: Hard to digest. The nutrients in corn is far less than in rice.
Wheat: The available nutrients from wheat is poor because of the digestibility of the grain.
Soybean: Contains large quantities of natural toxins or "antinutrients".
Corn, Soy and Wheat are three of the biggest culprits as far as food allergies in dogs. Itchy, red, flakey skin, a dull coat and intestinal upset are common symptoms of food allergies.
Soybean meal, wheat, corn glutens, corn meal, whole corn, crushed corn and ground corn are commonly used for their protein content in pet foods and are generally poor sources of protein vs. meat. Corn gluten meal or wheat middlings added to pet foods are the leftovers after the grain has been processed for human use, containing little nutritional value.
Brewer's Rice: The small milled fragment of rice kernels that have been separated from the larger kernels of milled rice and is a lower quality rice product that is missing many of the nutrients found in ground white rice and ground brown rice. It is basically a waste product of the alcohol industry.
Food Colorings: Food colorings are still commonly used in pet foods despite the fact that they are not necessary and some have been linked to medical problems.

The Ugly

Chemical Preservatives: BHA, BHT, propylene glycol (also used as a less-toxic version of automotive antifreeze), and ethoxyquin are found in many pet foods. Scientific studies have shown that these chemicals can promote liver disease and other medical problems including seizures and cancer.
By-Products: They can consist of the internal parts of animals such as necks, heads, undeveloped eggs, feet, intestines, lungs, spleen and liver and almost all the other parts not generally consumed by humans.
Animal Fat, Tallow and Meat meal: Processed dead dogs, cats and other animal materials, zoo animals, road kill and 4D (dead, diseased, dying and decaying) livestock by a rendering plant. These plants are depositories for restaurant grease and garbage, meats and baked goods past the expiration dates (Styrofoam trays and shrink-wrap included). In the United States these animal parts are denaturing before rendering with substances that include crude carbolic acid (a constituent of coal tar), fuel oil, or citronella (used to repel insects).
Animal Digest: Animal Digest is a cooked-down broth made from unspecified parts of unspecified animals. There is no control over quality or contamination.
