Sleepwalking Dog

This post is dedicated to a dog who I actually find interesting and entertaining! “Bizkit“

I think dogs make great companions and friends, but at this point in my life I see no need to own one or spend money to take care of one. To all of my friends who read my blog, I would like to ask a pretty simple question. Can you tell me what stage of sleep this dog is likely to be in during this video? For all of my friends who are in Vet. or Med. school this may seem like a simple question, but I challenge those of you who are not to leave your answers in the form of a comment. There are no rules to answering this so you can look up sleep cycles and so forth. Just a little question to stimulate interest in the brain and maybe help people learn something. I look forward to all your comments and answers!
