outside dogs?

[lute]

what does everyone think about keeping dogs outside, but bringing him in at night? i have a friend that lives in a very small town and lets her dog out in the morning and he stays outside all day hangin around town or in her yard. she doesn't hook him up or fence him in or anything.

i'm afraid he's gonna get hit by a car, although there aren't many that go through her area. there are no leash laws in her town.
