aww, don't you just hate it when they get scared like that. My sweet Annie seemed to have bad dreams a lot when I first got her. She was a rescued breeder from a puppy mill and it just broke my heart to think that what she had to endure was still seeping into her life. Fortunately, they happened less and less the longer she was with me.
But don't you wonder, good dreams or bad, do they dream like us? Do they see, hear, talk, experience sensations like we do in dreams? I'd love to know what really goes on in their little heads. How do the really perceive things that happen during the day, how do they dream? hmmm
Glad you were there to give her comfort so that she could go back to sleep.
