I wish to express my gratitude for your advice and recommendation.
My dogs coat had always been dull, tended to matt and dandruff was brought to the surface when she was groomed.
Following your advice I gave her Immune Aid (one scoop per day). Before one week had passed I could see the difference. It is now ten days, her coat is glossy black, silky to touch and hardly any dandruff is moved when I brush her.
In her 14th year she has the best coat of her life.
