Have you had an allergy test run? I kept changing foods and giving away what didn’t work and it was all most was as expensive as the test. Now I have exactly what I need to look out for in allergies for Callie. Which helps my research. My sister in law has a blond Goldendoodle and she will NOT give him anything with beef. She believes that is what turns the hair around his eyes dark. My gal is black so don’t have to worry about that. Good luck with your search.
