Corrina, sorry to hear about Merlins problem, poor boy. Sorry that I don't have any knowledge to pass on, but, in case no-one comes up with anything from personal experience, I did have a search round on the net and found this place that may have stuff that can help.

On this page I think the moisture plus skin spray looks good ..

There are a lot more pages in this section, mostly shampoos and conditioners but there is some stuff that may fit the bill so it may be worth a look-see.

Also worth a look is the skin section - look on the left hand side to click to - once there you will find a number of company logos. Some do have lotions and creams along with shampoos etc, and they also have some good supplements in various forms. One, Lambert Kay, had a product called Shed relief which l think sounds good.

Hugs to Merlin
Chris
