Its really funny you ask, because as I was pondering what they do I look down at Gwenndilyn and she's twitching. From her nose to her tail, she's just having those little twitches where I can tell she must be running in her dream.
Then suddenly she's opens her eyes and looks up at me. Wonder if she caught whatever she was chasing or maybe something was chasing her and scared her awake
Finnigan always is curled into a little ball and doesn't make a peep while he's sleeping.
Its funny to think about what dog dreams are like.
