Vicki, I have a book that shows all the patterns for the breed trims, but doesn't show the "generic" trims also used, like the "puppy clips'.
Basically, the body (including underside) is done with a number four or five blade, starting at the back of the skull. Do the legs as well and the very base of the tail.
Once that is done, you would comb the hair on the ears down straight and trim so that it lies even with the edge of the ears.
With the tail you hold it out straight, comb it out, and scissor the hair to desired length. For the paws you comb the hair out around them and scissor it closely (I use a curved scissors for this, makes it much easier.) Comb the hair between the toes up and between the toes and scissor that away.
For the underside of the paws you want a 10 blade on the clippers. Spread the toes away from the main pad and clip out the hair there with the clippers (be careful not to nick the dog, it's close in there)
The head and face are the hard parts. You want to first part the hair side to side on the top of the head, scissor away the front of the hair where it hangs in the eyes so you have sort of a curved "visor".
Comb all the hair left behind back and part it down the middle. Using the ten blade with a 4 comb on it, clip each side to blend with the hair over the ears and the neck.
For the rest of the face I like to leave a moustache on a puppy clip. You use the five blade to trim a gap from the visor down to where you want the moustache to start (I use the corner of the lips).
Now, part the hair on the muzzle down the middle, and trim it away (use short scissors with blunted tips) from the lips and bottom of the nose.
I also do a "sanitary" clip on dogs, which involves cleaning up around the penis in male dogs (be sure to use a scissors to trim the long hairs away from the end of the penis sheath) and running a shaved path up to the anus on both genders.
On both genders use the blunt scissors to trim any long hairs that waste might stick to.
You will need:
Oster or Andis clippers (not cheap human hair trimmers)
5 blade
10 blade
4 comb
Cool=lube spray (used while working to cool clipper blades and clean them.
Soak type blade cleaner (used after work. Blades can be left in a container with this)
A good straight and a good curved scissors
Good blunt tipped short scissors
(finger rings for scissors)
fine and wide toothed "greyhound" combs
Good nail clippers
Quik-stop in case you nick the dog or cut a claw too close.
As you can see; it isn't as easy as it looks (at least not until you do it a few times), and it still requires a substantial outlay in equipment.
On the bright side, if you have horses, the clippers with a broad "cow" head on them can be used on fetlocks and bridle paths (to do body clipping on horses you need an Oster or Andis livestock clippers--dog clippers are not up to dealing with large amts of horse hair)
Always remember, it's HAIR!! It DOES grow out.
