I looked for nine months for a young adult. I filled out many rescue
applications in hopes of rescueing a pup that needed a good home.
I never heard back from any of them. I presume because I worked.
I had two rescues in the past(i was a stay at home mom at the time) and had them until they were put down
at 17yrs and 16yrs having both from young adults but this didn't matter.
If you work full time they will not give you a dog. I got tired of waiting
and bought Buddy as a 14wk old puppy. It was time consuming.
I had more stress than fun and gave up most of my life. Once he was
with me I could not give him up. After that first year things became
easier. Much easier. Today we're a team. It was hard only because I
worked but he is loved and spoiled rotten.
If you have the time get a puppy if not look for a rescue. Yorkies
are puppies even as adults so the only thing you will miss is the
work the first year

Good luck to you and welcome to YT.
