Molly snores too. She also makes these little sucking type noises too when she's in a deeper sleep.
I remember some of the dogs from my childhood on that snored too as well as twitched and made little noises while dreaming. These were chihuahuas, min. schnauzers and Irish Wolfhounds. So, I would say that all (breeds) dogs snore and make noises while sleeping/dreaming. lol
