Another cold weekend is upon us in the Midwest.  The temperatures topped out at 30 degrees earlier this week and the dogs thoroughly enjoyed it.  I can watch dogs play for hours, practicing their predatory behaviors on each other.  Right now I have four dogs in the house, 2 being mine and 2 being a friends.  Very different breeds with very different play styles - getting along none the less.  One is a Dane and the other is a lab mix and both have similar play styles, with the "boxing" motion of their front feet.  The other two are an English Bulldog and a Border Collie mix.  It is wonderful to watch the BC herding the bulldog and the bulldog "pouncing" at her back.  As I watch them play I can see the natural instincts that they were bred for and the jobs they desire to do.  Back in the house, all napping peacefully they morph back into my beloved pets curled at my feet.  The wondrous dog!
