If so, what do you think they are dreaming about?

Diamond howls, barks and growls in her sleep. maybe she is dreaming about her old family and what they done to her or being left alone. not sure.

Diamond that's a great question.
I see Roxy twitching and making little sounds, haven't heard her howl yet though. I have no idea what dogs dream about. I would love to know!

That's an interesting question. I don't imagine that they are as complex as human bad dreams but I think it's probable that they do.

I've had my dogs crying in their their sleep. Sounds so sad. Running, barking, jerking ect all happens .
My cat will jump a foot while sleeping like he's getting away from something.
So they all do dream...big grin
