Our New Dog (Mutt) for the day

Our neighbor Gwen's daughter found a dog hanging around one day. They already have a dog and we had been thinking about getting one, so we asked if we could keep it while trying to find it's owner. We posted ads on KSL and signs around the area. We held this dog and played with it and really thought it was cute until night came. We had recently fenced our yard and it is summer, so we left the dog in the back yard. In the morning it was gone. It had dug under the fence to visit our other neighbor's yorkie. We put the dog back in our yard and placed a rock over the hole it dug. Within minutes, it had dug another hole and gotten out. Our neighbor was getting annoyed. We borrowed a leash for the night. Mark didn't want the dog in the house. All was quiet until just as we were falling asleep the crying began. First the dog yelped, then he whined and then the yowling started. Nothing would shut the dog up. This went on for a couple of hours. I turned to Mark in bed. "What should we do? Should we let him in?" Mark replied, "No way, let him go...perminently." I was upset he would suggest such a thing. Another half our of crying went on. We both couldn't sleep and I quietly slipped out of bed and let the doggie in. I put him in the mudroom where he couldn't hurt anything and slept in quiet the rest of the night. In the morning we let the dog out and he was once again on a long leash. He wasn't liking that, but what could we do. The little escape artist wouldn't stay in the yard. The crying began once more. Meanwhile of course no one had called to clain the mutt. I think someone had dropped him off far away in hopes he wouldn't come back. Gwen showed up on my doorstep and asked what she could do to help. She said her 15 year old daughter was crying in her room because of the dumb dog's crying and they hadn't slept all night. I was pulling my hair out by then and really regretted asking for the dog. I didn't say one word to Gwen, but silently handed her the dog and shut the door. Goodbye doggie!
