I didn't take her to the vet, but that's only because there are probably 30+ small animal vets in this town. As I said earlier, I put an ad on craigslist, in the (only) newspaper in the town, and informed the humane society of her presence.
I havn't taken her to see if she is microchipped. I might see if the shelter will do that for me. The reasons I've been hesitant are these...
1) I've hit the 3 major spots where someone would be looking for a lost dog
2) I had a VERY bad experience with finding a lost dog a few years back, owners didn't even bother looking for the dog for a week. When I went to return him, they told me stories about how he would jump out of the second story window, and their daughter would lock the cat in the closet ALL day so he would be there when she got home from school. There were other stories too, but I'm not sure I can post them here. I have little to no sympathy for people who can't be bothered to pick up a copy of the local newspaper or put a call in to the humane society to pick up their dog.
That said, if they contact me, I will return her. I would just have a very difficult time returning a dog to a situation like the one before, and I don't want to seek out a home which doesn't really care about her.
