I didn't mean to imply that all ear infections are caused by food. Our first experience with yeast infections in a dogs ears was with our first rotti..Nikita. She had them constantly no matter how clean I kept her ears. The vet said she had narrow ear canals and would likely have chronic infections. Kiki has it in her left ear only and that is the side that her head looks as though it was smashed in. Again all the cleaning and meds have not stopped this problem. i believe that the article i read on food allergies causing ear and other areas of yeast infection stated it was too much starch and sugars in the food that were the problem. This wasn't the main reason I took them off bagged food. We tried 3 different foods since the end of January and Monty would be sick to his stomach nearly everyday without fail. he has stopped vomiting since the raw diet thank God and both dogs seem much happier and more content. I don't know how long we will continue with this raw food diet but guess if they stay healthy and are happy we will keep them on it. It's a lot more work than I like at times and that's the downfall. I sure hope nobody was offended by my post. That wasn't my intention at all. I love it here and enjoy everything about the group.
