I use Royal Canin # 33 for both my 9 month old Yorkie and my 7 year old Papillion. They both have sensitive stomachs and the Papillion had skin problems. Since being on the Royal Canin for a little over 3 months both issues with the dogs have disappeared. I fed Baron Royal Canin puppy # 27 until 3 weeks ago. He did great on it... Hope this helps.
