I have cleared up the ear problems with my dauchshund mix with grain free food and ALWAYS rinse her ears out when she gets a bath every 3 weeks or so. Moisture in her ear will cause problems. The rinse I use is from Dr Foster’s and Smith, but you can get same from the vet or PetMeds. Haven’t had an ear flare up in two years now!
For her anal glands it is about the fiber in kibble. When she starts having a problem, dragging her butt on the ground etc, I add pumpkin or yougart and it works for her.
She doesn’t eat grains or potatoes. I tried Nutrisca brand and they didn’t like-too much peas. Nutrisource GF lamb was a good food, but started not agreeing after second bag. Currently using Earthborn Meadow and they love it and both my dogs are doing very well. Sample of Earthborn Great Plains for their treat and the love the bison too. I use the tub for a spoon of topper, but remove the whole garbanzo bean, creates gas, whoa,. I might need to add some pumpkin, fiber count is a little low for them.
Hope this helps!
