sorry - she does actually get treated with Stronghold every 4 weeks, we last did her on Sunday. As she's not scratching her ears or shaking her head and some wax has actually worked its way out onto the (beige!) carpet, which I first thought it was a small lump of poo!
I'm inclined to see how it goes over the next couple of days with a view to taking her to the vet if it doesn't improve.
I think it probably means we'll just have to be rigorous in making sure she's done every 4 weeks and the vet did say they can take quite a while to get rid of - the puddie equivalent of athlete's foot I think!
for the advice and good luck to Lisa with her crew's ears
