<human>: I live in an apartment complex in a largely college town. 

My neighbor doesn't take her dog for walks, she just lets him out and he runs all over the neighborhood. I don't think he's aggressive, but upon seeing anyone he'll run up to them barking and people are clearly unnerved by it. Same story if there's another dog with them. When the dog gets close to people it appears friendly. The owner appears to have very little control over the animal, too. She'll call it in to the house and it will flat ignore her. 

Her excuse is that she feels bad because the dog is used to her parents' large back yard. The barking doesn't really bother me. The concern I have is that it spends a lot of time in the street and will only make a small step to avoid cars. 

My question is: is this okay for a dog to have so few boundaries and should I really be worried about it being hit by a car? It's a dog, it can't be that stupid - right?

Condense the text into a few key points
<bot>: dog has free run of the neighborhood and I think it's only a matter of time before it gets hit by a car or shot/maced by a pedestrian.
