Yet another false lead

Poor KJ. She's hysterical right now. We just ran up to Lake Cyrus to look at a dog that wasn't Buddy once again. This was the people from yesterday. I had gotten an anonymous phone call (at 5:45 AM!!) that these people had a dog in their backyard the last couple of days that looked like Buddy. I drove up there yesterday, they weren't home so I put a flyer in their mailbox. They left a nasty message today around 6 PM telling me "your dog Buddy is here ONCE again and we would appreciate it if you picked him up IMMEDIATELY." I called the lady right back and she made a really weird comment about how she hopes I reimburse her for all the dog food he's eaten the last couple of months. She said this dog has been coming around their house 3 to 4 times/week for the last 7 or 8 months. I knew in my heart it wasn't Buddy but had to know (how the hell would his little shih tzu legs get him up to Lake Cyrus 3 to 4 times/week????). Sure enough, KJ & I drove up there and it wasn't Buddy. I had to take KJ w/ me because T is babysitting for neighbors down the street. Big mistake. She's been crying since we left that house. She wants to know why hasn't anyone returned him, why should somebody get to keep him, he's our pet and we paid for him, she wants him back, etc. I've been trying to prepare her for the fact that he may not be coming back, that someone else may have found him and wants to keep him. That just makes her SOOO mad. She said that's stealing.
