So a coworker found an abandoned Chinese Crested out in the rain shivering two nights ago.
He looks kinda like this (no camera at work):

He had a red shirt on and a fake cheeseburger crystal collar. He was SUPER skinny, so it looks like he's been lost for a while. No tags, no tattoos, no microchip (he's been taken to the vet). He's clearly a purebred which makes his lack of ID totally puzzling.
They're looking for the owner right now, but if they can't find him they will take him to the shelter where he'll probably be gassed.

I kind of want to adopt him but I'm worried when/if they find the owner my heart will be torn asunder. JUST LIKE MARY WORTH AND CHESTER. I've also never owned a dog on my own (only with my family) and am worried about the cost/difficulty of boarding when I'm on trips, etc. Though I guess that's just life and you learn to kennel or something.
Should I adopt this dog??? WHAT SHOULD I DOOOOOooooo
