Our dog spends some time on our bed but not in it. He sleeps in his own bed in the hallway next to our bedroom from 11.pm and usually re-joins us between 5 & 7.am. If it's hot he'll lie on the floor at the foot of the bed and if it's cold he's in the middle of us & we're on the outside edges ? When we got our first dog many years ago I was scared of dogs & I said she couldn't get on our bed at all, but she quickly won me over & that didn't last long. For me the magic cuddles of a snuggly doggy that loves you just can't be beaten.
