Right now, I have a beautiful black lab mix in my backyard. I know where she lives, I know who her "owners" are. They keep her in their backyard with no shelter and food and water every other day. She constantly gets out of their low-fenced back yard and I often find her wandering the busy street close to our houses. I bring her back, they say "oh... just put her in the backyard." and promptly shut the door in my face. No 'thanks', no nothing. This girl is SO sweet. When you walk towards her, she pees and cowers, it's horrible. I assure her she's a good girl, and once she knows I'm not there to harm her, she drowns me in sloppy kisses. It's been raining here almost constantly for the past week and a half or so. She has shelter in my backyard. I don't know if I should return her to these horrible people, or take her to a shelter... or what? I would keep her, but funds say otherwise right now. I would feel really bad returning her to these ungrateful and cruel people, but I'm not sure what the right thing is to do here? Any advice, please.

Thank you.
