My WB/TB has rainscald on his head (one side along his ear and above his left eye and cheek). It's rather unsightly to say the least, and at present I am treating it using Camrosa or Sudacrem. I thought I'd got on top of it, but it has returned and is obviously itchy so I've started the Camrosa again. Any ideas on treating this? First time he's had it, but he does suffer from mud fever which strangely he hasnt got this year (yet!).
