From a groomers point of view, be careful with the furminator, Mars King and tools with blades as you can strip too much coat out if you are not careful, especially in long coated breeds. The shedding rake (hacksaw type blade) is one of the best for short coated breeds.
IMHO : The best thing is, when in malting season, regular baths with a hydro bath and a good strong dryer to blow the coat. Both the bath and dryer help to stimulate the hair follicles and loosen a lot of the dead hair, then the shedding rake after. I would do this every week for 2-3 weeks and you will be amazed the difference it will make.
