Mr. Brown can Moo; can you?

Do you remember that Dr. Seus book? Well, our dog, when sleeping, occasionally moos. It's really weird. It's definitely not a howl or a moan, it's a strong moo sound. At 3 am it's really disconcerting to hear that kind of sound coming from Bram's bedroom. However, I've been informed that however disconcerting it may be, Lloyd really doesn't want to hear about it or discuss it at 3 am. It can wait until morning. I just assumed that if it woke me up, it would have also woken him up. Apparently not.
