My current dog is a vocal sleeper. I made a language inspired by the noises he makes when he’s dreaming.
My previous dog loved to chase our cat. He’d be lying on the couch, and` she would walk up to him and start poking him with her snout to try to get him to run. He would either stay put or slowly slink away.
My first dog would make this happy grunting noise when she saw someone she knew.
Sometimes my bunny will fall asleep with his chin on his litterbox in such a way that it makes him snore really loud. Sometimes people in my meetings can hear it.
