BARF diet, an acronym that stands for Bones and Raw Food, or Biologically Appropriate Raw Food. It is suggested that adult dogs would thrive on an evolutionary diet based on what canines ate before they became domesticated: Raw, meaty bones and vegetable scrap. The BARF diet is gaining popularity abroad as well as in Japan. Note that the raw meat diet alone will be deficient in a few essential nutrients. The best is to mix with regular pet food so you provide your pet with a healthy balance.
