Hi,
As said before, there should be no hand-stripping on a Sheltie type coat.
You will probably be amazed at the difference a groomer can make with a bath, a 'blaster' and the right brush. Hopefully this will get all the dead coat out. Feet and back legs up to hock joint should be 'tidied', but apart from that no scissors allowed for show purposes - but don't discount this for pet purposes either if it is a true Sheltie type coat as trimming or even worse clipping just makes the coat matt more.
From then on in, the trick really is to keep on top of it, little and often. Particular attention should be paid to spots behind ears and elbows, round neck where collar sits and on inner thighs on mine when they've been tramping through the forests.
