I expect Dr Rusbridge is off work over Christmas - I hope she is, because she works extremely hard and is so good at helping our SM Cavaliers. I'm sure she will get back to you once she is back at work in the new year. If the Mediterranean is having the same sort of weather as we are having in Britain, with the air pressure going up and down in huge leaps, that may be why Bliss has been a bit scratchy - it really does affect dogs with CM/SM.
I hope you will be able to find some answers in the new year,
Kate, Oliver and Aled
