I ran into this pup on one of her first days in the city, after moving here from Texas. She was a little intimidated by all the noise, fuss, and people, but I saw her again a few days later and she seemed to be settling in quite well.
Aaaand I managed to delete the note that had her name on it. Hopefully her parents will drop by and see her and remind me. She lives in the Russian Hill/Polk Street area, so it may be that Tidus is going to have a new playmate!
Edit: Mom chimed in below, and it turns out her name is Lina. Yay, Lina!
