I know you've already made up your mind, but I just thought i'd also add my 2 cents, just in case. I adopted my dog from the shelter, and he had been caged with small dogs and around lots of small dogs without ever having a problem, and when he came home with me he was alright for a little while with the neighborhood little dogs and cats. BUT once he got used to his new home, his tolerance of small animals completely took a 180 out of nowhere and now I have to turn the other way if I ever see a small creature while walking him. so, I would just use caution if you change your mind and decide to adopt.
