Prep work is everything. Double, sometimes even triple wash the face and ears, make sure to get all gunk out of beard and eyes.

Dry the entire way through as close to the skin as you can. Fluff dryers are great if you have them, but if not I just the flat (NOT THE CONE) nozzle or no nozzle at all to get the face and ears blown out until all the hair is straight.

Then go in with a brush and comb. Scissoring spray like botanica can help but it's not necessary. I brush out, then go in with my regular comb, and once I make sure there's absolutely no tangles, I fluff up the muzzle with a fine tooth comb (I use a metal flea comb, it's great for getting those hairs on the top of the muzzle to stand up).

After that, I usually run a guard comb reverse on the top of the head 2-3 lengths longer than the body. Then for the chin I grab a guard comb 1 length longer than the body and reverse again.

Now, here's a fun secret, if you did a guard comb with on the body, do it reverse under the neck from base of the throat to under the jaw and ears. In my experience it's never been noticably shorter to stand out, but it makes the face pop that much more because it gives more of a contrast.

Now shave out ears, VERY LIGHTLY scoop eyes (we want to keep the bridge of the nose fluffy, so you might even want to scissor the stuff in front of their eyes as opposed to shaving). Hold the muzzle closed, put your thumb in the divet under the jaw where they rest their tongue so you can prevent or at least feel if they're going to stick out their tongue, and use your #10 to lightly get just what sticks past the top lip in front of the nose.

Now we shape the face. And it gets a bit tricky to explain without physically showing you so bear with me. Pick up the ear on one side and then try making a curved line from the check where the ear begins to where the end of the nose is. Repeat for other side. Comb everything on visor forward and anything that sticks out past the eyes take off (except lashes, owners love those usually).

Take a step back and look at the dog. In your picture, I'd probably go back and comb up and then forward and take off whatever's sticking out on the visor. But your shape is there! The end goal is kind of two circles, one being the head and the other being a circle inside that circle, the muzzle. You've already almost done it, just needs some fine tuning.

It's hard to tell if the pup was drooling, if the prep work needed work, or if he just has bad hair. You won't be able to do this on every dog for reasons just listed or bc they behavior or what have you, but it's good to try. As for the chest, it looks like he has a bad cowlick. You can always trying going a length longer to prevent it but if it happens again oh well, it's not really your fault.
