So, Morgan currently knows two commands, "sit" and "lie down". He is about 99% accurate with them at this point, but every once in a while he'll get them mixed up if he's really excited about something. Usually what happens is when told to "sit", he will lie down instead. Then when you remind him that he was supposed to sit, he will thump his front paws on the ground -while still lying down- as if to say "I am!!! I am!!!!". If you remind him a third time, he will finally get into a sitting position like he's supposed to. I really wish I had video of it, because it is really funny. The other quirky thing he will do is what we call the "puppy prance". Especially now that his legs are getting longer he will do this little high-step dance anytime he's really proud of something... usually if he finds a toy that was hidden or if someone tells him he's a good boy. He also does it a lot when he picks up and carries dry leaves around in the backyard. It is soooooo cute!! What kind of quirks and cutesy things do your dogs do?
