Hi Jean & Ray
This is quite a difficult dilemma as you will have discovered that many high street groomers clip Cockers automatically :-( Your best chance would be to locate an experienced Cocker breeder/exhibitor as some offer a grooming service for pet Cockers or to ask around locally for recommendations of other groomers who are willing & able to hand-strip a Cocker - perhaps you see other owners of pet Cockers around & like the way some of them are trimmed? If not, perhaps you could
register with this forum & leave your location & email address - it's possible I could recommend someone in your area who will be able to help.
