34. Dogs

Dogs are renowned for their expressive sleep, often twitching, barking, or even “running” as they dream during REM sleep—just like humans. Their sleep patterns are incredibly adaptable, changing based on their environment, daily routines, and the habits of their owners.
Whether stretched out in the sun or curled up at the foot of your bed, dogs showcase a blend of deep rest and playful dreaming every time they snooze. AKC
