I use an Oscar Frank curved slicker. They are pretty stiff right out of the box so I soften them up by smooshing them on a flat surface until the needles give a little. Heavy shedding, I 'scoop' the brush backwards in small sections. You will be amazed at how quickly you will fill this brush. Run it backwards on your jeans and it comes out in one clump, then back at it. Smooth and clean debris by going with the lay of the coat. It takes out burrs and matts like magic. I also use it in the tub. Soap the dog up and run the brush through, clear the drain or you will both drown. Run the brush through the damp coat a couple of times and you will be good to go. You will still have 'loosies', the guard hairs, but your vacuum will be forever grateful for this method.
