Question Author
Hi Illyria, thank you very much for your prompt and informative response. We only have Jack, but he socialises in the park with his "doggy friends", and I wanted to keep him out of the way of them until I knew otherwise. Now he will have to wait until he is all better! I have just re-read my post and can clearly see where the misunderstanding came from-sorry!
I have been following your hygiene advice anyway, and I am dissuading him from licking (difficult, as his tongue is never in!) and rubbing-hard for him, as it must be driving him mad! Resorted to a bedtime rawhide too, to distract him a little and save him spending all night mithering his eye.
Thank you, Lisa. x
