One thing I have noticed over the years with my Yorkies, is that they do tend to have sensitive tummies. Since all the problems with commercial pet food have come to light this year I'm always nervous. I too fed Royal Canin but they had food that was recalled. My two boys would not touch a new opened bag. I settled on Canidae wet and dry and have been feeding it since early June. It's human grade food. I honestly won't go back to any big company brand named foods. It is possible that it is the food. Was the bag recently opened? Don't mean to scare you but you just don't know anymore. Keep us all posted on how things are going with your baby.
