Welcome to YorkieTalk.
There are several issues here beyond appearance.
First, the fact that she was selling her pups through a drive-thru window. That really bothers me. If she does that, what else does she do or not do for that matter? I think you may be looking at a pup with some serious health issues down the road if you're not careful.
Then, you weren't able to see the sire or even a photo. I would question that.
The mom looks like a yorkie to me, but you need to be concerned about more than appearance. It also doesn't
look like she has LP, liver shunt, heartworms, etc... but who knows? Chances are there's no health guarantee either.
I would walk away even if it means losing a couple hundred dollars. The right pup is worth waiting for.
I am proud of you for asking questions. When we know better, we do better.
