F***ing loud-ass ankle biters! Chihuahuas are more common, but they are not the only ones. They are one person dogs, meaning they are delightful to that one person, but horrid to anyone else. Add to that the carelessness some owners exhibit by failing to train their tiny beasts, and you get "small dog syndrome," which is more aptly titled, "my dog is a sh*t because I can't be arsed to train the feral little bastard" syndrome.
Trust me, I live in an apartment complex that has a lot of these. gah. thanks for letting me vent, although I'm guessing that was not your intention, lol
