Over the years my dogs have had some issues like yours. The best food I have found for them are Wellness Core Dry Food and I have a dog food subscription from Farmers Dog – which is homemade and uses human grade ingredients. My dogs love it. They are also white dogs and I struggled with tear staining, but did not want to treat with chemicals. Using the Wellness dry food and Farmers Dog food as a topper, the tear stains are gone. Also smaller poops, no throwing up, no loose or greasy stools.
Good luck to you.
