One summer we had a German Shepherd visiting every day. I didn't mind, she was nice and played in the sandbox with my two sons, who were little at the time. I got worried because she was crossing the street to get to us and didn't seem to ever want to go home. I called the number on the tags but didn't get an answer.
A week later I get a call from a guy who wanted to know why we called his house(he had caller ID). I asked him if he owned the dog and told him that she had spent quite a few days with us and I just wanted to let him know she was running loose. He had hired a kid to watch her and feed her and had no idea the whole time he was gone that the dog was running all over the neighborhood! You just don't know with pet sitters what is going on while you're gone. Sadly though, she got hit by the school bus the following year. We still have pictures of "Duchess" playing with my kids that summer.
I wanted to ad that I'm one of those people who if they find a stray will drive up and down the block to find the owner. Last year I chased some pot belly pigs out of the road and back into what I had hoped was their house
It was quite a funny sight! I left a note on the door because I couldn't catch the darn things but scared them enough to keep them in the yard. I did have the right house I found out later when I stopped back by.
