Thank you all for your input and advice, we are trying to persevere with the fuciderm with limited success, Wills has upped his co-operation fee to a sausage now, and he's still not that co-operative. It's so annoying, if only he would let us treat it I'm sure it would clear up.
Once the small tube of fuciderm is finished, a review with the Vet and a decision to be made. It's re-assuring to hear from those who have gone thro' with the procedure that it seems to have worked.
