Are you interested in feeding your dog on the diet for which he/she is evolutionarily designed? Then you should consider BARF, Biologically Appropriate Raw Food or Bones And Raw Food. Clicking on the link on the left will take you to Dr Ian Billinghurst's website where you can begin your investigation into BARF.
Dr Billinghurst has also written a couple of books on the subject, which are well worth getting hold of. You can find them on the website too.
