For many dog lovers they have at one point or another have seen their dog in a middle of a dream. Just laying on the floor lowly growling or whining or just on the run. It's hard to tell if a dream is good or bad, but it seems other dogs know the difference.

Take for example this little golden retriever puppy. This little guy was just sleeping alongside this older dog. Then the older dog began dreaming and the little puppy was so worried he calmed him down and then cuddled up with him.
