The effectiveness of the de-shedding brush is incredible. We use it for our English Cocker Spaniel Frankie, and it picks up more than 10x the amount of hair as our standard shedding comb from Pet Barn. The slicker brush is easy to use, especially for combing Frankie's fringe out of her ears. We definitely recommend getting the Dyson trigger lock to make things easier - I even use it when vacuuming the house.
