brewer's yeast is found in many dog foods, but it is actually a common allergen found in dogs , and can be toxic. It is cheep, and that is why its in so many dog foods. The yeast that is highly nutritional for your dog and your self is Nutritional Yeast. Nutritional yeast can also be expensive, 1lb. for $7 - $8. But believe me , well worth the cost. My dog had an ongoing ear infection in her ear for years on and off. After using doctors medicine with no luck of getting better at all, I got the ear tested to see what type of bacteria was causing the ear infections, and the results were that she had a yeast infection in her ear. The whole time i have been giving her great dog-food, but little did i know that the dog food contained Brewer's Yeast. I immediately changed her dod food to Azmira Holistic dog Food, which is very simple and free of all common allergens and free of all yeast, and she loves it sooooo much! I also made a mixture of Nzymes ox-e-drops, Grapefruit-Seed-Extract
(grapefruit extract), and which hazel, and mild soothing herbs. I added a few drops or squirts of this special mixture to her ear every day twice a day consistently for almost 3 weeks. No more ear problems at all. Completely gone! Her ear sparkles now! I also sprinkle Nutritional yeast and garlic powder on her food for her health and her coat, and to ward off the fleas. She never has any kind of body oder, and always smells really good! Please switch to Nutritional yeast, its amazing!
By the way..... What kind of dog food do you feed your dog? What breed is your dog?
i hope this can help
