Hello Maria and Ziggy and Welcome to Yorkie Talk.  My Papillion had really bad flaky and itcky skin for 6 years.  We were always @ the Vets!!  I got my 14 month old Yorkie Baron 8 months ago.  He was on Purina Puppy and had terrible gas from it.  I got Royal Canin on my cousins insistance.  Adult # 27 for the boys...Her last 4 Yorkies all lived to be 14 and over!!  Wuthin 6 weeks we had no more skin/or upset stomachs.  They love the food and I could'nt be happier!!  I Highly Recommend this food for your dog.  You may have to try different kinds to see what best  suits your dogs needs.  Royal Canin has a Yorkie formula that might fit your dogs nutritional needs!!  I have a Yorkie and a Papillion that's why a chose a small dog formula for 11 months and older!!  Good-Luck...
