I'm a pretty light sleeper, and even in an Olympic queen size bed (slightly smaller than a king, 5 inches wider than standard queen), it gets crowded with 2 people and a dog or dogs. It would be impossible to cram all 4 of us up there, esp as my husband is a big guy (6 foot 4 inches tall) and tends to hog the bed when he's asleep . Tasha sometimes will sleep with us if there is a thunderstorm and I usually don't sleep as well on those nights because my movement is limited and I wake when she moves around. If David is out of town she always sleeps with me though and I have no problem then since there is plenty of room. Most the time the pups sleep on their own bed in a room right next to ours. They know its their bed and when we say "is it bedtime?" they will run upstairs and go to bed on their own.
