Charlie had the same thing late last summer and early fall. I did a little research about allergies and food and discovered that many Yorkies are allergic to the corn in their dry food. Sure enough, I checked the Royal Canin he was eating - and loved - and discovered that corn is one of the fillers in it. I switched him to Innova Evo and he cleared up within a couple of weeks. I'm now feeding him Chicken Soup, which he likes better, and haven't had any problems.
Good luck. |
