Raw feeding
Raw Feeding is the practice of feeding pets, especially dogs, what is believed to be a species appropriate diet largely consisting of uncooked meat. Practitioners often cite evidence that domesticated dogs have very similar gastrointestinal systems to wolves. Raw feeders are commonly opposed to commercial dog foods, which they believe to be harmful. There exist other moral, health and cost reasons as well.
One popular raw diet is the "Bones and Raw Food" model which includes non-meats and numerous supplements along with careful preparation and measuring. Another model is a "Whole Prey" diet which simulates the proportions of an actual prey animal in a pet's diet. This includes organ meat, heads, fur (and feathers and scales), skin, muscle, and bone, but no other supplements.
Proponents of raw feeding are often vehement in their belief of its superiority to a commercial diet as it affects the health, disposition and longevity of their pets. It is believed by many raw feeders that veterinarians who are opposed to raw feeding are influenced by academic departments that rely upon funding from pet food companies and by their own desire to profit from selling special dietary commercial pet food.
Most specific evidence that raw feeding is beneficial is anecdotal, limited to the experiences of a few authors and website maintainers, although the basic principles are supported scientifically.
