DH and I are both light sleepers, our little dog is very nervous and reacts to every noise and if he slept on our bed I don’t think any of us would get much sleep. He has slept in his crate which is covered on three sides by a blanket since we first had him as a puppy. He goes in at 10pm and we never hear a peep out of him until my husband goes down at 7:30am even if there are noises such as thunder or fireworks. When we watched the tennis match the weekend before last he was later than usual and ran into his crate when we opened the door. This arrangement suits us but each to his own,
