We don't really have internal doors in this house. There's one to the bathroom (thank goodness), and another going from the house to my studio. But that's it.
This means that we have no means of stopping the dogs leaving their comfy 'rest-a-while' chew-proof black plastic beds, and settling down for the night in the sitting room; which they are perfectly welcome to do.
However, they are banned from sleeping on the sofas at night (or any time), so I always put chairs on them before I go to bed.
Bok couldn't care less. Even if he has to sleep with chair legs up his 'Whitehall farce', he will do so just to be awkward.
This is how I found him this morning; he was still half asleep.
..... and don't you stick your tongue out at me, you Monkey!
