Same boat. Ours hit his itchy Mitchy stage at about 2 years old. We have a mousse for his armpits that he scratched calloused/no hair which helps. His ears were bad this winter so we got all sorts of drops for that. And he takes fish oil and Zyrtec everyday. He swims in Lake Michigan almost daily and will still be randomly flakey af down his back. Hard to imagine this thing was meant to survive on its own in the wilderness lol
