My dogs do dream, but Molly is the most active dreamer. She is also the one most likely to want to chase after something, stick her nose in a hole, or try to climb a tree after a squirrel. She makes a noise in her sleep that's somewhere between a bark and a hiccup, and can be so loud it has wakened me on occasion. Shadow and Lily are usually quiet, but do twitch like they are running. With his size and the length of his legs, Shadow is like rockhillmanor's Great Danes: you don't want him near any breakable furniture. Of course, like most greyhounds, he is usually sleeping on a couch or soft bed.
