The other week after a trip to the pond I was puppy sitting the neighbor's dog. I left my problem Clover dog off of her 15 ft "convict chain" so that she could play, and play she did with the other dog. Gee I thought we are finally making some progress in keeping her in the yard. Eventually I wanted to go in, so I called out "let's go in". The neighbor's dog and Clover's little brother Barney started to head for the door. Clover on the other hand shot off like a rocket into the woods. No doubt she didn't want to go in.
