Wow... this women just butchered this dog with those clippers !
She just seems so harsh... plus she is using a #10 blade which in my opinion and from my own experience is way to short for a Yorkie. Also, I would not consider what she did to be a modified Schnauzer cut this is more of a Joey cut with some very choppy looking cut on the legs.
If someone did that to my dog I would be pissed.
Another very interesting site with some god awful hair cuts on Yorkies. Some are ok but the majority of them are not.

Just sharing and giving you all something to think about before diving into that first do it yourself hair cut on your pups. They may not be the best at first but with practice you can master the perfect look for your babies.
