I know people talk in their sleep (my third eldest sister and her college roommate had long conversations into the night. I know, I was there on some weekends to visit. There was no sleep those nights), but my dog growls in is sleep sometimes.
He’s doing it right now as he sleeps under the piano. Every now and then he’s just snoring, but sometimes he’s growling at whatever he’s dreaming about.
