My pup is a talker. He is when he's a wake and he really is when he sleeps. Sometimes (like now) it sounds like he's purring. It's this wonderful rumbly snore sound. He also whimpers, grunts, chuffs and quietly barks. The thing that truly amazed me was 3 nights ago when he howled. Yep, he howled in his sleep
So, what sounds does your dog make while sleeping?
