Then order the Master Groomer Flexible Slicker (it is amazing for getting out matts and puppy fuzz. ) This is your shedding and dematting slicker for heavy duty once a week sessions.

Order the double-wide dark blue firm one. ($9.99) If you're going to be doing your own grooming and you're feeling flush order a second one, a single, at $7.99 If you hit a matt that you can't untangle, you can cut it (carefully, pinching it with your fingers next to the skin and clipping it with your scissors lengthwise, not straight across.) Then lay the matt against your hand and brush with your single width slicker. Don't yank, just brush until the matt breaks up. You may need to make several clips with the scissor, always protecting the skin by pinching the matt next to the skin. This works great for behind the ear, under the armpits and those pesky "pants" area tangles.
When you have all the matts out use your rake. I happen to like this one because the double teeth are good a 'catching' the undercoat. (and it's cheap, too. $7.99) Once you're matt free with your slicker, this will get out most undercoat.

When grooming your puppy, always start at the bottom (bottom of legs, bottom of tummy, bottonm of chest) and work upwards. Lift the coat with your hand and brush down in the direction of growth in a line. When you remove coat and are tangle free, move up an inch or so and repeat. This is called 'line brushing' and a it's very effective way to work on your dog, looking around for boo-boo's, lumps, bumps, rashes, ticks, fleas and examine your dog as you groom.
You don't have to do the whole dog all at once, pups can be done a section at a time. It's a great way to introduce grooming if you do a little bit every day, passing out liberal treats for cooperation makes it less stressful for pup.
