No tags or anything? She looks pretty old...I'm betting she has some medical issues the owners couldn't pay for and they just turned her loose.
Actually shes only about 1 and a half, and very healthy. She isnt housebroken, and shes terrified of guys, so Im thinking she pissed on the floor and the guy tossed her out. Shes a bit on the skinny side though. Ive got to get a pic of her sitting on my Honda.
I hate to say this but God do I hate those dogs. Ever since Taco bell used that one Chiwauwau in their commercial, my neighborhood is flooded with them. The thing I hate most about them is they bark so damn much and don't know when to quit. My neighbor's chiwauwau constantly tries to pick a fight with my 120lb rotweiler. Somebody really needs to smack some sense into those things.
