Does anyone have any experience of this and the treatment please ?

Someone on FB has just had their TM diagnosed with this, vet recommends drilling out and flushing at monthly intervals.
Apparently it's usually found in Springers.
Just looking for a bit more info for the owner.

Try googling for Canine Aspergillosis and there is a wealth of info on the internet.This is a link to just one page.
