Won't he drool on your pillow? 
Actually, he doesnt drool, but he licks the shit out of it until its wet. Im used to it and change sheets/covers daily right before I sleep.
I really should just not let him on the bed in the first place, but fuck that. I am too much of a push over to stop my dog from doing something he likes. Hes even got a doggy bed right next to mine but only uses it when I am sleeping.
Besides, he is the protector of my domain. Whenever the cat tries to get on my bed the dog herds him away. So he gets a reward. (Not that I dislike the cat, but that fucking thing pooped in my bed once and isnt allowed near it anymore.)
