The acronym once used by raw-feeders to describe the meaty bones they fed to their dogs was BARF (bones and raw food). This term was introduced by Ian Billinghurst, an Australian veterinarian. The acronym took on a new meaning over time and was called "biologically appropriate raw food". Currently, most refer to this type of diet simply as "raw".

The once radical idea of feeding dogs a diet that is fresh, varied and rich with amino acids and enzymes that have not been altered or destroyed by cooking has become accepted and in some cases even preferred.

Many will switch their dogs over to a BARF diet when they are dealing with health issues. However, there are more and more proactive dog owners who are not waiting until illness strikes to give their dog this healthful diet.

There are a growing number of manufacturers packaging freeze-dried or frozen raw diets even though many veterinarians are a bit unsettled by this type of diet for dogs. When you think about it, it seems perfectly natural. This diet, consisting of the elements a canine would eat in the wild (raw meat, uncooked bones, and crushed fruits and vegetables), is a natural means of nutrition for dogs.

The concerns voiced, however, are not completely unwarranted. Risk of dietary imbalances, bacterial contamination and possible inadequate chewing of bones causing internal injuries are real concerns. A balanced nutritional diet is key to a dog's good health. For example, inadequate levels of calcium can present risk for orthopedic issues which can become severe.

It is important to know the source of the food and to research the manufacturer to be certain that what you are purchasing for your dog is healthy and free of additives and preservatives. The raw bones should be pulverized to reduce the risk of injury or choking from large pieces of bones. Cooked bones can splinter and should not be fed to dogs. Know the facility that is processing the food. Good hygiene is important when the food is handled.
 
Although a raw diet for dogs is a healthy option for most canines, it is important to consider the circumstances of the animal prior to altering its diet. For example, a dog who has a compromised immune function may be harmed more than helped. If a dog is healthy, it won't be affected by otherwise dangerous bacteria such as E. coli or salmonella.

Health benefits aside, a major drawback to feeding a dog a raw "BARF" diet is its cost. Done the proper way, this type of regime for your animal can cost as much as it costs to feed yourself. For many, the costs of this diet may be prohibitive. So, raw may be a welcomed occasional treat rather than daily fare for your furry friend.
