Undoubtedly the best dog grooming tool out there for dogs with thick undercoats - I have tried them all; AND it's cheaper than the most highly recommended grooming tool for dogs with thick coats/undercoats, by about $60!
Dog has been shedding like mad. Been brushing him regularly but still have fur everywhere. The rake design helps get loose fur beneath and has greatly reduced the shedding. The dog seems to take on to this rake more than brushes
