Hello. I am sending this message from Japan.
I'm an owner of a cairn terrier,and looking for a grooming video/dvd for cairns.
Unfortunately, there's no information about cairns in Japan and
most trimmers can't strip cairns very well.  So I decided to learn by myself.
I hope I could find it!

Simpsons do one and also if you go onto our dogs website they do a very large range of videos.

Cairns are not really that difficult to learn to do as you can handstip the fur out and they are supposed to look kind of scruffy.  It will be the face which will be the difficult part until you get the knack of it.
