I have a Sheltie boy 8 months old, his face always become red and scratch and then hair off and the skin will become red and a little bit up, then I use some cream and it become pink colour after a few hours and then after about 2 to 3 weeks, the hair will grow and become normal but after a few weeks, it become the same thing again.
Is there any method that I can treat him so that this will not happen again?
Thanks!
