Hi There!
I'm pretty new to YT to, but only in 2 short months I've learned soooo much.( Thanks to the wonderfull people on here).
When it comes to itchy skin, I'll try adding Missing Link Supplement to her kibble and also I'll bath her more often ( maybe once every 10 days).
Plus that previous comments are absolutelly right, It might be the corn in the food You use ,and try using mosturizing shampoo and conditioner ( I use Petsilk and LOVE IT)
Well ,good luck and stick around
