If you notice the article even says, ""As they get older, and you know that they are healthy and you don't have any parasites, you could, again, stay away from the face, as far as licking and things like that, but if they want to sleep in the bed, that would be OK."
There is really no danger from the dogs sleeping with us.....it is the fleas, worms, and viruses. So if our dogs have none of those things, there really is no more danger than a person. So far, my 3 dogs let me share their King sized bed and I am hoping they continue their generosity.
