My spuddie has very dry skin and gets flakey. I've also noticed he has some rough spots on his rear that have become darkend. Almost looks rash like to an extent. Not painful for him but have no clue why it's happening. I purchased some emu oil shampoo and after his bath put pure coconut oil on him. This still isn't enough to keep his skin hydrated and stop him from scratching. If I keep a shirt on him it stops him from clawing his skin open but then his flakey skin gets worse. Any suggestions on how to keep his skin more hydrated and why his skin is becoming rough and darkened on his rear. This would be most helpful.
