Awww, you made me cry. We had a lab called Charlie and he was the best friend anyone could wish for. When our daughter was born, we had to buy a baby gate after a week, because Charlie would lay across the doorway into her room and I would fall over him as I stumbled around half asleep to pick her up in the night. We used the gate to stop him coming all the way up the stairs, but if she awoke, so would he. Consequently anyone would know what sort of a night we had had just by looking at his eyes. If they were red and bloodshot, you knew the baby had been awake loads. As she started to crawl, he would lay across the room she was in to stop her getting out and when she started to walk, he would lay up against the sofa so that she could use him as a step to get up or as a cushion in case she fell off.
We lost him when he was 13 and we all still miss him. Anyone who has, or has lost, a lab and has read Marley and Me would understand.
