>the other clipped ,she has been neutered and her coat has turned fluffy and dfficult to keep.
The joys of neutered dogs :(
If you would like her to look
like she should, and she has plenty of harsh hair rather than cotton wool then hand stripping would be better for her coat, it will keep the coat hard and ensure that she remains waterproof ;) If she's a puppy then stripping out the puppy fluff will do wonders for her coat :) Make sure the groomer knows how to hand strip though as some say they will hand strip and don't

Clipping the coat will result in the undercoat growing out the same length as the outer coat and lead to a coat which is difficult to keep tidy and not waterproof. It can take ages (at least 6 months) after being clipped to get back to a stripped coat ;)
It's actually possible for the owner to handstrip and isn't as difficult as it sounds al you need is a rubber glove or some chalk dust ;) info

here don't worry that they aren't Lakeland terriers, you can get plenty of pictures to follow ;)
