"One of the BEST tools for removing dead undercoat"
The Furminator is one of the most heavily used tools. I do a lot of Deshedding on German Shepherds, Huskies, Goldens, Labradors, & pretty much every coat that it won't damage. It's one of the BEST tools for removing dead undercoat on double coats dogs. With an ANDIS COMB in a close second. You'll want to use this brush minimally as too much brushing may irritate the skin.
