will anyone tell me whats the best barf diet i can can feed my dogue de bordeaux?

There is not such a thing as the best Barf diet , the Barf diet is a diet and only one.

Buy a couple books before you start so you fully understand.

Natural Nutrition for cats and dogs ( the ultimate diet)  is a good book by Kymythy R Schultze

Give your dog a bone, Dr I  Billinghurst,   Raw Meaty Bones by Tom Lonsdale are all good books.

Buy the first one, it is the least expensive and quite digestable.
