The Bark

The other day, Poly was sound asleep and presumably dreaming about chasing some sort of prey (she is a hunting dog after all).  She began to bark and bark and bark to the point where she woke herself up.  Then, she started barking again having been awakened by a bark - no doubt she had to find out the source of that bark.  She was very confused, but I admit it was really funny to watch!  Is that wrong?  LOL
