First you need a bathed and blow dried victim...errr...dog. I usually shampoo twice, but before a clip it is especially important to have a really clean coat.
Andis clippers w/30 blade and the attachable comb I'll use. It is a 1 in comb and, because I clip Woo against the grain, it will cut a bit shorter. My shears can be seen in the grooming tools along with brushes.
I start with clipping the body. When you are using a blade, always clip WITH the grain of the hair. I am clipping the opposite way with this comb because Woo has such a fine coat that it leaves a nicer finish this way. If I am cutting without a comb and just a blade, unless I am doing a surgical clip I cut with the grain of the hair.
