Thanks everyone for ALL of your wonderful advice and suggestions.
I usually finish an entire 5 lb-ish bag before moving on.
I will take it all into account when trying to make a decision as to what to try.
Something my DH brought up was maybe he just has dry skin. In that case maybe a fish oil supplement or fish based food might help.
What do you think (summer air conditioner & fall heater = dry skin) ?
Goint to pick up some Acana Pacifica today. Trial 1lb bag and see how that goes.
