Stray

I found a stray dog in front of my home today and I walked it all over the neighborhood trying to find its home, but I couldn't. I thought about leaving it and let it wander home (since it can't get home from my backyard), but it got dark and the dog almost got hit by a car. Also, if she didn't wander home after a few hours she might not go home. Of course, she's now in my backyard. She's a beautiful, kind collie mix that's very well behaved and I'm trying desperately not to fall in love with her. Tomorrow I have to call the pound and see if anyone reported her missing. I don't want to send her to the pound, but if I don't find the owners in a few days I'm going to have to. I already have 3 dogs and that's the legal limit where I live. Plus, I don't have the ability to bring another dog into my home.
Everyone else in my neighborhood said they'd seen the dog wandering for hours, but not one bothered to do anything about it. Why are people so self-centered? The dog kept almost getting hit, it wouldn't have survived the night. I'm disappointed in humans tonight.
