Run away!!! Multiple times! In 2012 I had the hardest time keeping Lolli and Buddy home. They knew the minute I forgot to put their Invisible Fence collars on them, and they ran as soon as my back was turned. They were gone overnight twice!
And Lolli occasionally gives me mini heart attacks by not moving when I talk to her in the morning. I don't know if she is sleeping really deep, or ignoring me, but sometimes she doesn't move and scares the crap out of me for a few seconds.
