If anything, you might also have them switch shampoo/conditioner to something more for moisture and sensitive skin like something oatmeal based or for puppies (unless they have an oatmeal allergy). And maybe even apply something like an edible oil to help with the dryness.
I recently started my girl on a coconut oil regime. I'd feed her a little bit of it and use a few drops to massage into her paw pads (they aren't exactly crusty dry, but they have been drier than usual) and belly area. Just enough to rub some on, not to make her too greasy. I may even rub a drop or two into her fur, though it's mostly for shine as she always have soft fur. Either way at first she'll still look slightly greasy but it'll absorb into the hair leave it shinier. When applying to fur and skin (exclude paw pads) always rub the oil in your hands so it'll warm up and spread better. And always use organic coconut oil (the kind that solidifies). For her I may do it once a week, in your case I might suggest doing it twice a week. Best after a bath of course when the skin is moistened and softened.
