I used to let both my dogs sleep on a blanket on my bed.
However after a while my old dog kept creeping closer to me and off HIS blanket.
In the end he was trying to sleep with his head on MY pillow and I felt so sorry for him when I had to growl (LOL) at him in the middle of the night for getting off his own blanket.
So I stopped it altogether as I do not like dog hair in my bed.
Bought two more dog beds and put them in my room so they could sleep near me, but not with me!
