I have a dog with environmental allergies and she has been doing very well since starting allergen specific immunotherapy four years ago. Her diet is varied, a quality kibble with a bit of cooked meat, chicken, egg or turkey as a topper.
We just started Orijen 6 fish, but she also does well on Nutrisca Salmon and Chickpea as a base.
The dermatologist told me her diet has nothing to do with her allergies, she does have a sensitive stomach however. I add a little water to her meals also.
I would be careful about making dramatic changes to a senior dog’s diet, maybe check with your vet as there are prescription dog foods specially formulated for specific conditions.
I might be concerned about the possibility of diarrhea with all those veggies mentioned in your diet, I’ve never heard of DH Hash.
How about Malaseb shampoo? Weekly bathing might help. My dog gets bathed twice a week with Malaseb.
