I also cut the tail hair off. . On the sides I just cut a straight line between legs halfway between body and floor, without cutting the leg hair. You can ease the clipper down on the sides to taper the hair. This is how all my boy's are cut once they're finished showing and they love it. This is Judge in a semi-show cut without the topknot.
Next step are the ears.
The tips should not have any hair on them. I look at the back of the dogs ear and picture a wide V shape. Shave everything off inside the V and leave all hair on the outside of the V. Repeat steps on inside of ear. . The tippy top should make a point. I use scissors to finish off the edges of the ear.
