I've been wanting to start this thread for awhile. I absolutely love the way my terrier/cocker mix, Solomon, wags his tail back and forth with such exhuberance that he has dents in his fur on both sides of his hips! He'll just be standing, looking around at stuff, with his tail in full swing - for no apparent reason. He sometimes sits up on his haunches to look out the window while I'm driving - it's really cute! He also JUMPS really big jumps - straight up in the air when he's happy, or when I say' "Boing!", which is pretty often What do yours do that just make you smile every time?
