dog tired
Meaning
To be extremely exhausted or utterly worn out, often to the point of needing immediate rest.
Origin
Imagine a loyal hunting dog, after a relentless day of tracking, running, and chasing, finally collapsing in a heap, utterly spent. This powerful image of canine exhaustion—where a dog, having given its absolute all, sinks into a profound, immediate sleep—is the heart of the phrase 'dog tired'. It's a direct, visceral nod to the animal's capacity for intense effort followed by an equally intense, undeniable need for rest, evoking a level of weariness so deep it makes you want to curl up and sleep anywhere, just like a spent hound.
Examples
- After a long day of hiking, I was absolutely dog tired and fell asleep as soon as my head hit the pillow.
- The children played so energetically at the park that by dinner time, they were completely dog tired.
