Harry does that, too! And sometimes that little wooop booop tiny bark with his mouth closed which makes his body jump a little! And the legs doing pretend running! And (the sweetest!) little sucky noises with his mouth, as though he's still nursing from his mother
My daughter used to tell me, when it was happening with Rosie our labrador, that she was having
the best dream and was chasing all her best friends through the woods! Awwww
