I prefer the undercoat rake, wide tooth and a greyhound comb after to get loose hairs. I like to do a good bath when the coat is showing those tufts coming out of the shoulder and rearend. When soaped up for the second time I use the undercoat rake gently and tons of dead coat will come off. Then I use my fingers and loosen it up around the neck, chest and all through the body some more. Rinse really well and then towel well. Finish it off with the High Velocity dryer and watch the snowstorm! I usually repeat this again in 2 weeks and maybe a 3rd time until it's all gone.
