I have never tried Royal Canin. My kidz was on Wellness, and I switched to Bil-Jac. Today was their first day on it. I place equal amounts of Wellness & Bil-Jac in their bowl and each one picked out the Bil-Jac and left the Wellness.
I am trying Bil-Jac because it has been recommended on this site and seems lots of yorkie lovers get great results using it. Thanks, everyone for the information.
