I wonder if this is how  Lassie dogs and cats find their way back home (sometimes) from hundreds of miles away.  The most interesting part of the article for me was learning that people actually have jobs where they stand in a field and watch dogs do their business.  I wonder what their job title is...LOL

Good one Karen!  And there could be a Squatter Spotter assisting the Squatter Plotter. :)
