I groom myself also. BUT Uni is the easiest yorkie on the face of the earth to groom, so I guess i am spoiled. However, when I WAS trimming her, I just looked at a pic of a yorkie I wanted her to look like and clipped away. It's best to have good quality scissors. Some cheap scissors don't cut the hair well, and end up pushing the hair out of the blades instead of cutting it all, if that makes sense. and you get a slanted cut where you wanted it to be straight.
For tipping the ears, you can use those plastic eyebrow shavers if they are scared of the clippers sound near their ear (or if you are scared to do it! LOL). If you do use clippers for the ears, do NOT go up the side edges of the ear, only along the flat part of the ear, otherwise you will end up with a mangled ear
. Also the thing that you use to trim nose hairs can be used to cut the hair between the toes.
Don't forget to try to make it a happy bonding experience. They will trust you more and more and it will get easier and easier.
I read someone on Yt said, Why should I pay someone to mess up my dog's hair when I can do it myself for free?
love that!
