When our dog is in full-on lazy mode, he will sit like this at our barking station (aka window) with his head supported for prime intruder viewing. But when an intruder does appear, lazy mode produces a low grade "boof" sound instead of a bark. If several boofs don't do the job, then barking commences. It's a very technical process.
It also helps to clutch a Garfield blanket for moral support.
