Tjukurpa -
He has itchy, slightly grotty ears most of the time, and I can't see any pattern as to when it's worse (apart from when I get slack about cleaning his ears). The ulcers on his eyelids and mouth only form when his ears get infected. The skin break-down on his foot happened when his ears were infected about 18 mths ago. I guess that whatever triggers the ear infection, triggers the other symptoms.
I haven't actually had him tested to find out what it is that bothers him.
I made a mistake about the cortisone (sorry). When his ears were infected they were treated with anti-biotic drops. I clean his ears up to every second day (it's lucky he's such a forgiving dog - mayby I should just say it's lucky he's a Koolie - if I had to do this with my Foxy she'd be thoroughly peeved with me) with Bayer Clean Ear Solution and this generally controls the itch, I guess by removing the wax/goop.
When his ears start to get itchy he rubs them on the ground. This has got increase the chance of infections, I think, putting dirt and germs into the ear.
My 'feeling' (for what it's worth) about this is that the fact that he is a really sensitive, stressy dog contributes.
