i use the FURminator on my GSDs .......wow its good
you do have to be careful as you can get a bit carried away and end up with a bald dog lmao....

never press too hard just go with the flow ..

always brush in the direction of the hair..

unclog it after each stroke..

make sure the dog is clean and completely dry first..

never use it on a dog that has a dry/brittle coat..

and don't go over the same spot over and over again like i did or you end up with a larger version of a Mexican hairless

and mind around the fury plumbs or you wont get many pups in the future
