Very effective product to clean and treat dog's ears

I have a standard poodle who is very prone to ear infections. We have taken her to the vet many times and have her on a very specialized diet to prevent these. I also clean and pluck her ears regularly. However she still gets horrible ear infections. Eco Ears is the only product we have found that really helps dry up and clean out the infection and get her ears to a place where she is not scratching and shaking her head all the time. It also really helps with the smell! It is easily ordered on Amazon, made in the USA and has natural ingredients.
