Dog food is plant or animal material intended for consumption by dogs or other Canidaes. Special dog foods given as a reward, and not as a staple, are known as dog treats.

Some people make their own dog food or feed their dogs meals made from ingredients purchased in grocery or health-food stores; many others rely on commercially manufactured dog food.

There are many different recommendations on what diet is best for dogs. Some people argue that dogs have thrived off of leftovers and scraps from their human owners for thousands of years and that commercial dog foods (which have only been available for the past century) contain poor-quality meats, Food additives, and other ingredients dogs should not ingest, or that commercial dog food is not nutritionally sufficient for their dogs.

Homemade diets Different homemade diets are recommended by various experts, from "natural" diets consisting primarily of Raw feeding, to vegetarian diets consisting only of nutritionally balanced vegetarian ingredients, to mixtures consisting of ingredients such as brown rice, brown pasta, meats, Egg (food)s, and vegetables. A problem with homemade diets, frequently articulated by veterinarians, is the difficulty to consistently provide the dog with a complete and balanced diet. This "technique-sensitivity" will be a challenging part of providing a truly superior diet to the higher quality brands readily available by retail in most urban and suburban areas.

Most dogs willingly eat vegetables, particularly if they are cooked, and many kinds of fruit, although chocolate, coffee, onions, macadamia nuts, and bread dough can be poisonous in dogs. Grapes and raisins are also Grape and raisin toxicity in dogss. Avocados have in two cases been associated with heart failure in dogs.

Commercial dog food

By its water content, commercial dog food can be categorized into following types: dry, semi-moist, and moist.

Dry dog food The average dry food is the least expensive, per pound, when compared to its canned (wet) or semi-moist counterparts. It is usually 6-10% moisture by volume, as compared to up to 78% in canned food. It can be beneficial in the prevention of tartar buildup, as well as being less likely to spoil quickly than an open can.Messonnier, S. (2001) Natural Health Bible for Dogs & Cats. New York: Three Rivers Press. ISBN:0-7615-2673-0 However, if cans are opened only at the time of feeding, they will tend to keep longer than dry food, as dry food cannot be opened on an as-needed basis, and is by necessity exposed to air for the duration of its use.

The manufacturing process Pellets of dry dog food, called kibble, is primarily produced by one of two methods: extrusion and baking. During the extrusion process, cut dough or a mixture of raw materials is fed into an expander, while pressurized steam or hot water is added. When removed from the high pressure that results, the pellets puff like popcorn. The resultant kibble is allowed to dry, then sprayed with vitamins, Fat, or any other ingredients that are not heat-tolerant.

If extruded kibble is exposed to air for too long or not properly stored, the fats and oils added after cooking can become rancid, and vitamins and minerals in the food may be destroyed by heat during storage or shipping.

Baked kibble is often sought after by pet owners seeking a more natural or more digestible food, although the effect of baking on either of these factors is the subject of much discussion (see below). Because the heating process is slower, kibble being prepared this way is subjected to a lower pressure for a much longer period of time. Because fat can be cooked in rather than sprayed on, baked kibble will tend to have a slightly longer shelf life compared to extruded kibble, especially when exposed to air, or after its package has been opened by the consumer.

Because of the longer shelf life and less efficient cooking methods, baked kibble will tend to have a notably higher price tag, and is generally only available in pet and specialty stores, rather than supermarkets. There is persistent debate within the pet care industry as to which method is better for the dog nutritionally. Some proponents of baked food assert that baking aids in the digestibility of raw proteins, and that extrusion requires the use of harmful preservatives, such as BHT or Ethoxyquin. How Flint River Ranch Food is Made However, it has been pointed out that the canine digestive system is tailored to eating raw meat in the natural environment, and that many extruded foods use natural preservatives, such as tocopherols.

As with any cooking procedure, the simple act of preparing kibble destroys many nutrients in raw ingredients. It has been suggested that either baking or extrusion{{cite web |title = timberwolforganics.com |url = http://timberwolforganics.com/s.nl/it.I/id.9/.f;jsessionid=ac112b1b1f43047a367ceb0a41f48477b125b5e68867.e3eTaxmKbNaNe34Pa38Ta38Lax90 |work = Top FAQs.--> is less harmful to the nutrient content of a food, but no conclusive evidence has been presented in either direction, and the argument continues.

Wet dog food Wet, or canned, dog food is significantly higher in moisture than dry or semi-moist food. Because the food is sterilized after being canned (sometimes it is also cooked in the can), it is often easier to ensure the sterility of wet food. A given wet food will often be higher in protein or fat when compared to a similar kibble on a dry matter basis (a measure which ignores moisture). However, because water accounts for so much of the food, the canned food will generally be lower in protein and fat in terms of actual content.

Fresh dog food Fresh dog food is a new category of dog food founded in Australia a decade ago. It has recently made its way into the American market. Fresh dog food uses the pasteurization instead of the traditional extrusion method used to process pet food. This processing technique makes fresh dog food more vulnerable to bacteria compare to dry and wet dog food. To prevent spoilage, refrigerators are used as storage instead of shelves. Fresh dog foods are highly palatable, contains zero preservative (BHA, BHT, Ethoxyquin), and use only fresh wholesome ingredients.

Contents Many commercial dog foods are made from materials unusable or less desirable for human consumption. These may include:

Meat by-products or digests (which may include euthanized animals{{cite web

Meat and bone meal
Cereals by-products
Horse meat

Less expensive dog foods generally include less meat, and more meat by-product and grain "fillers". Proponents of a more natural diet criticize the use of such ingredients, and point out that regulations allow for packaging that might lead a consumer to believe that they were buying a natural food when, in reality, the food might be comprised mostly of ingredients such as those listed above.http://www.wysong.net/dontbefooled/ingredientgame.shtmlhttp://www.homevet.com/petcare/foodbook.html However, several pet foods exist which do not contain any of these ingredients. Such brands may include Evanger's and Tripett. Many pet stores stock well-known brands that are free of by-products, and run at around the same price as some grocery store brands. More expensive dogs foods may be made of ingredients suitable for human consumption, organic products, or free-range meats.

Special varieties There are dog foods specially formulated for dogs allergic to common ingredients such as chicken, wheat, or corn. These foods usually contain "novel proteins" and substitute uncommon starches for the usual grains. Meats used in allergy formulas can range from the mundane, such as lamb, beef or Whitefish (fisheries term), to the unusual, such as venison or duck. Carbohydrates in allergy formulas are usually a less common grain, such as rice or barley, but such ingredients as potato and quinoa are sometimes used.

Some foods are designed for dogs with maladies such as urinary tract infections, and some are tailored to the dietary needs of especially young or aging dogs. There are also vegetarian dog foods for owners who do not want their dogs to consume meat products.

Premium labels Certain manufacturers label their products with terms such as premium, ultra premium, natural and holistic. Such terms currently have no official definitions so caveat emptor applies. The AAFCO is currently looking to define some of the terms.

There are also varieties of dog food labeled as "human-grade food". Although no official definition of such term exists, the assumption is that other brands use foods that would not pass US Food and Drug Administration inspection according to the Pure Food and Drug Act or the Meat Inspection Act.

Raw food Raw food is also a growing industry

Recalls .

The 2007 pet food recalls involved the massive Product recall of many brands of domestic cat and domestic dog foods beginning in March 2007. The recalls came in response to reports of renal failure in pets consuming mostly wet pet foods made with Wheat gluten (food) from a single People's Republic of China company, beginning in February 2007. After more than three weeks of complaints from consumers, the recall began voluntarily with the Canada company Menu Foods on March 16 2007, when a company test showed sickness and death in some of the test animals. Soon after, there were numerous media reports of animal deaths as a result of kidney failure, and several other companies who received the contaminated wheat gluten also voluntarily recalled dozens of pet food brands.

By the end of March, veterinary organizations reported more than 100 pet deaths amongst nearly 500 cases of kidney failure, with one online database self-reporting as many as 3,600 deaths as of April 11. As of April 8, Menu Foods has confirmed only about 16 deaths. The U.S. Food and Drug Administration refuses to estimate the amount of sick or dead because there is no centralized government records database of animal sickness or death in the United States as there are with humans (such as the Centers for Disease Control). As a result, many sources speculate that the actual number of affected pets may never be known and experts are concerned that the actual death toll could potentially reach into the thousands.

Overall, several major companies have recalled more than 100 brands of pet foods, with most of the recalled product coming from Menu Foods. Although there are several theories of the source of the agent causing sickness in affected animals, with extensive government and private testing and forensic research, to date, no definitive cause has been isolated. As of April 10, the most likely cause, according to the FDA, though not yet proven, is indicated by the presence of melamine in wheat gluten in the affected foods. The Chinese company behind the contaminated wheat gluten has initially denied any involvement in the contamination, but is cooperating with Chinese and American investigators.

In the United States, there has been extensive media coverage of the recall. There has been widespread public outrage and calls for government regulation of pet foods, which had previously been self-regulated by pet food manufacturers. The United States Senate held an oversight hearing on the matter by April 12. The economic impact on the pet food market has been extensive, with Menu Foods losing roughly United States Dollar30 Million alone from the recall. The events have caused distrust of most processed pet foods in some consumers.

Past recalls In 1995 there was a dog food recall when the Nature’s Recipe company pulled thousands of tons of dog food off the shelf after consumers complained that their dogs were vomiting and losing their appetite. Nature’s Recipe’s loss amounted to $20 million. The problem was a fungus that produced vomitoxin (or “mycotoxin,” a toxic substance produced by mold) contaminating the wheat.

In 1999, another fungal toxin triggered the recall of dry dog food made by Doane Pet Care at one of its plants, including Ol’ Roy (Wal-Mart’s brand) and 53 other brands. This time, the toxin killed 25 dogs.{{cite web| url = http://www.api4animals.org/facts.php?p=359&more=1| title = Animal Protection Institute (API)-->

A 2005 consumer alert was released for contaminated Diamond pet foods for dogs and cats. Over 100 canine deaths and at least one feline fatality have been linked to Diamond pet foods contaminated by the potentially deadly toxin Aflatoxin, according to Cornell University veterinarians.{{cite web| url = http://www.news.cornell.edu/stories/Jan06/dogs.dying.ssl.html| title = The Cornell Vet College-->
