Love this tool! Tried two other brushes before I saw the ad for the Furever brush, and neither of them made a dent in my Terv's undercoat. My husband and I were like, 'Wow, the boy doesn't shed!' One stroke of the Furever brush proved us wrong! By the time I was done, Monty had to be 2 pounds lighter. And he tolerated the brushing without complaint. Five star brush!
