Kefir for your dog !

I have read about this kefir in another thread. But I am now well-versed with kefir and in fact, I only learned about it in forums. This reminds me when the hype on raw chicken meat hit our country, the shih tzu club had advocated it. There were 2 of my friends who were feeding their shih tzu with raw chicken meat until they realized that it was not good and that cooked chicken meat is better. So in that same vein, I would wait for some more time for this kefir to be proven beneficial to dogs.
