I have 4 Yorkies and also had this problem. My 2 smallest Yorkies kept ear infections all the time and my 2 larger Yorkie’s were constantly throwing up the yellow foam stuff, as well as sometimes food. I always research brands and buy them the very best rated food. The last 3 brands I’ve tried are Fromm Gold Grain Free Duck (can & dry), Merrick Grain Free Duck & Sweet Potatoes ( can & dry) and Zignature Limited Ingredients Trout & Salmon (can & dry). All 3 brands are all #1 highly rated dog food….BUT, there’s something in the Fromm and the Merrick that doesn’t agree with all 4 of them! The Zignature is the only one that agrees with all of them 100%. No more ear infections and no more throwing up!! Another helpful hint is to add coconut oil once a day to their food!!
