Commercially prepared pet foods are available in several forms that vary according to the processing methods, the ingredients included, and the methods of preservation. Foods can also be categorized according to their nutrient content, the purpose for which they are formulated, and the quality of ingredients they contain. One of the broadest classifications of commercial pet foods divides products according to processing method, methods of preservation, and moisture content; these categories are the dry, wet, and semimoist foods.

Dry and wet food
Commercially prepared pet foods are available in several forms that vary according to the processing methods used, the ingredients included, and the methods of preservation. Foods can also be categorized according to their nutrient content, the purpose for which they are formulated, and the quality of ingredients they contain. One of the broadest classifications of commercial pet foods divides products according to processing method, methods of preservation, and moisture content; these categories are the dry, wet, and semimoist foods.
Dry food is the most common type of pet food. It is made from grain, meat, and vegetable ingredients that are dried and then ground into small pieces. Wet food is made from the same ingredients as dry food, but it is cooked and then canned. Semimoist food is a combination of dry and wet food. It is made from grain, meat, and vegetable ingredients that are dried and then cooked.
Dry food is typically stored in a sealed container to prevent it from absorbing moisture from the air. Wet food is typically stored in a refrigerator to keep it fresh. Semimoist food is typically stored in a sealed container to prevent it from absorbing moisture from the air.
The nutrient content of dry food is typically higher than that of wet food, as it is made from grain, meat, and vegetable ingredients that are dried and then ground into small pieces. The nutrient content of wet food is typically lower than that of dry food, as it is made from the same ingredients as dry food, but it is cooked and then canned. Semimoist food is typically lower in nutrient content than both dry and wet food, as it is made from a combination of dry and wet food.
The purpose for which these foods are formulated is also important. Dry food is typically formulated to meet the nutritional needs of adult dogs and cats, while wet food is typically formulated to meet the nutritional needs of puppies and kittens. Semimoist food is typically formulated to meet the nutritional needs of adult dogs and cats, but it may also be used to meet the nutritional needs of puppies and kittens.

Raw meat diets
Companion animal populations are an important part of our lives and share our home environments. The foods that we feed our dogs and cats may be a combination of commercially available raw meat diets, companion animal diets (soft/moist; dry/low moisture kibble-type products), and pet treats.
Commercially available raw meat diets have not been the subject of many recent large-scale pet food recalls, but they are an important potential source of zoonotic agents for owners and humans in contact with the animals.
Many of these products have been the subject of recalls by the FDA due to contamination of the product with various microbiological agents.
The majority of pet owners in the United States feed their companion animals commercially prepared pet foods. These products are available in several forms that vary according to the processing methods used, the ingredients included, and the methods of preservation.

Kibble-type products
The ingredients used in kibble-type products can vary widely, including meat, poultry, fish, grains, vegetables, and other sources of protein. The specific combination and proportion of ingredients are carefully selected to ensure the diet meets the nutritional requirements of the target animal species. Kibble-type products are often produced in various shapes, sizes, and textures, allowing for different chewing preferences and dietary needs.
These products are typically manufactured using different processing methods, such as extrusion, drying, or steaming, to shape and cook the ingredients. The processing techniques help to remove moisture and create a durable product that can be stored for extended periods without significant degradation. Kibble-type products are often packaged in convenient forms, such as bags or pouches, making them easy to handle and store for pet owners.
Preservation methods play a crucial role in extending the shelf life of kibble-type products. These may include adding preservatives, such as vitamins, minerals, or antioxidants, to maintain the nutritional value and prevent spoilage. Additionally, packaging techniques can be employed to create an oxygen-barrier that hinders the growth of microorganisms and ensures product freshness.

The majority of pet owners in the United States feed their companion animals commercially prepared pet foods, which are available in several forms that vary according to the processing methods, the ingredients included, and the methods of preservation. Foods can also be categorized according to their nutrient content, the purpose for which they are formulated, and the quality of ingredients they contain.

Commercially available raw meat diets have not been the subject of many recent large-scale pet food recalls, but they are an important potential source of zoonotic agents for owners and humans in contact with the owners.
A recent study analyzed 240 samples from 20 commercially prepared raw meat dog diets (beef, lamb, chicken, or turkey), 24 samples from 2 commercial dry dog foods, and 24 samples from 2 commercial canned foods.
Concerns exist about the nutritional adequacy of vegetarian companion animal diets, but these concerns are not limited to such diets, and include a wide range of meat-based companion animal food products. Indeed, it is highly plausible that repeated independent laboratory analyses of a range of commercial products, vegetarian or meat-based, would similarly demonstrate nutritional inadequacies and inconsistency of nutritional content over time. Such findings in no way negate the ability of well-formulated vegetarian or meat-based diets to meet all the nutritional requirements of the normal animals for whom they are intended; they merely illustrate the need for good quality control during production.

In recent years, a variety of foods have been developed to meet specific needs of some pet owners. Although concerns exist about the nutritional adequacy of vegetarian companion animal diets, these concerns are not limited to such diets, and include a wide range of meat-based companion animal food products. Indeed, it is highly plausible that repeated independent laboratory analyses of a range of commercial products, vegetarian or meat-based, would similarly demonstrate nutritional inadequacies and inconsistency of nutritional content over time. Of course, such findings in no way negate the ability of well-formulated vegetarian or meat-based diets to meet all the nutritional requirements of the normal animals for whom they are intended; they merely illustrate the need for good quality control during production.
