Dreaming Dogs

Lately I've been having the discussion with my best friend about whether or not dogs express their emotions physically. Of course they do to some extent- when they're sad or scared or happy there are certain behavioral signs to look for, but in general when a dog has a sad look on its face I don't think it necessarily sad. That could just be the way the dog looks and would be no indication for how it feels. Also, I hate it when people see their dog jumping around and barking in their sleep and they're like "Oh! He's having a dog dream!" How do you know? How do we know dogs dream at all. Maybe his muscles are just freaking out and it has no relation to his brain. Sometimes people do that too. For example, when I slept over at my friends house she woke me up because I was moving around and going crazy, but I wasn't having a dream at all. I was just sleeping. My best friend does it all the time too. She'll start talking in her sleep and thrashing around. But when I wake her up she's not dreaming. It's just a coincidence. Right now the only proof we really have for dreams is the fact that everyone admits they've had one. People tell us that they have had a dream and we know. So unless your dog tells you he had a dream you don't have any idea that he is.

Here are a couple of articles I found about dreaming: http://www.petplace.com/, http://www.professorshouse.com/

Also here is an article about how dogs may look guilty, but they actually aren't showing that dogs may look a certain way but it doesn't necessarily mean they're feeling it: http://www.foxnews.com/
