And I say to hell with them, the scientists that is. Our dogs are not allowed upstairs, so they do not share the bed matrimonial, but many is the time I have shared a bunk in my office with Biscuit, the more intelligent and less smelly of our labradors. (Due to my insomnia, not marital strife, since you ask.) As to sharing a bed with Denali, well, I love him, but I'm not insane. My rule is, if you have a penetrating, impossible to identify and eradicate odor, our love will have to be the unphysical sort. I know St. Francis of Assisi used to go about eating lepers' sores, or perhaps that was some other saint, but he was, while holy, let's be frank, a freak. And besides, many of the disease horror stories mentioned in the linked story involve cats, and who knows about cats. As to dogs, well of course, no licking of open sores, no wet kisses to the face, no sleeping in the bed if you have fleas (this should apply to human guests as well), no sharing food or bowls. But anyone who would not curl up with their dog for a nap doesn't deserve the honor of owning a dog IMHO.
