Welcome
Yorkies coats don't need to be stripped, you can use a regular clipper or just scissors, my groomer uses the clippers between my dogs feet and on their belly area because we do that nice and short and also on their back end, everything else she just uses scissors, but I keep mine fairly long- if you want to do a really short cut- you could use clippers all around.
You really need to use a good conditioner on Yorkie hair- it makes a HUGE difference.
Anyway- Ada is adorable- hope she finds a wonderful home
