Dogs are great.   They truly love you unconditionally and who else is as always happy to see you no matter what.    I had this Heinz 57 mix who was the typical dog always wanting to be with us and loving us conditionally.  He was different from all of the other dogs that I have had though.  He literally would smile when he saw us….a big toothy smile.    The first time he smiled at me, I thought that he was showing his teeth because of displeasure or that he felt threatened.   I asked him what was wrong.   He continued to smile and his tailed wagged even more out of control than what it had before.    It was then that I realized that he was actually smiling at me, just like a human.    It was an enduring quality that I will never forget even after all of the years he has been gone.
