First, I'm very sorry for your loss.
I had two minis and I had an Airdale as well! Obviously, yes, the mini is a lot smaller than the Airdale. And I can certainly understand wanting that smaller package - we lost our 110 lb Lab a few years ago and opted for a smaller dog just because, once he got older, Beau started having trouble getting around and it was very hard for us to help him.
So, I had two mini-schnauzers growing up and two distinctly different dogs. One, Fritz, my dad bought. One, Buster, was bequeathed to us from a very stern and not very loving man.
Fritz was an absolute delight. Yes, he had that inquisitive terrier demeanor but was basically an intelligent, eager to please, affectionate little guy who I loved dearly. I taught him (I was just a kid of 8 or 9 at the time) to "give hug" and "give bigger hug". He was a little darling.
Buster, on the other hand, had been roughly handled and was not a pleasant little dog. It wasn't his fault because he had been sternly raised and learned to fight back. He was also dropped into a family he didn't know - the only people he'd ever known were gone and, while we meant well, we didn't really do anything to ease his transition. He bit me - twice. :wow: (It really was my fault.)
So overall, given the right upbringing, these little guys are charming and affectionate, smart as a whip, generally good with children and other animals, and wonderful little family dogs. Those raised under different circumstances need a little extra care.
They are small and easy to handle, although they require routine grooming. They can have quite a few health issues (liver problems, thyroid issues, epilepsy) but I would still highly recommend the breed. They're darling little dogs.
As your profile notes you are from Oregon, I took the liberty of googling some breed rescue information. There is a mini schnauzer club in Portland that has a page on rescues here:
