I would look at are dog food rates some of those foods aren't to good I would go grain free maybe get a allergy test I had Franklin on about 5 different foods finally found the right one Fromm four star grain free beef frittata veg his fur is so much nicer his red face went away his tear stains are going away his spots on his back went away they were gross
but it all was from food I would try to go grain free stay away from chicken, corn a lot of people on here feed there dogs Fromm that have allergies an it works great it is expensive but well worth it in all reality it's a couple dollars more then blue buffalo I was feeding my two dogs blue buffalo 24lbs. Bag an it lasted maybe 2 1/2 3 weeks maybe an the Fromm for 2 dogs lasted a month an took all my dogs problems away I say yes it is well worth the money so I would keep trying foods until you figure something out good luck I really hope you find something to help your sweet baby
