Raw dog food diets are controversial. But the popularity of the diets — which emphasize raw meat, bones, fruits, and vegetables — is rising.
Racing greyhounds and sled dogs have long eaten raw food diets. Extending those feeding practices to the family pet is a more recent idea, proposed in 1993 by Australian veterinarian Ian Billinghurst. He called his feeding suggestions the BARF diet, an acronym that stands for Bones and Raw Food, or Biologically Appropriate Raw Food.
Billinghurst suggested that adult dogs would thrive on an evolutionary diet based on what canines ate before they became domesticated: Raw, meaty bones and vegetable scraps. Grain-based commercial pet foods, he contended, were harmful to a dog’s health.
Many mainstream veterinarians disagree, as does the FDA. The risks of raw diets have been documented in several studies published in veterinary journals.
Potential benefits of the raw dog food diet that supporters tout include:
Shinier coats
Healthier skin
Cleaner teeth
Higher energy levels
Smaller stools
Potential risks include:
Threats to human and dog health from bacteria in raw meat
An unbalanced diet that may damage the health of dogs if given for an extended period
Potential for whole bones to choke an animal, break teeth or cause an internal puncture
Since Billinghurst’s book,Give Your Dog a Bone, was published, several other types of raw dog food diets have emerged, including commercially processed raw food diets that are frozen or freeze-dried and combination diets that use blends of grains, vegetables, and vitamins that are mixed with raw meat purchased by the owner at the grocery store.
Raw dog food recipes and meal suggestions are readily found online and in books. Interest from pet owners continues to grow, with the widespread recall of melamine-contaminated pet food in 2007 bringing in new followers.
A raw dog food diet typically consists of:
Muscle meat, often still on the bone
Bones, either whole or ground
Organ meats such as livers and kidneys
Raw eggs
Vegetables like broccoli, spinach, and celery
Apples or other fruit
Some dairy, such as yogurt
