dog tired

Ready to collapse

Dog tired means extremely exhausted, utterly worn out.

The expression suggests the kind of deep fatigue that might follow sustained physical exertion—the way a working dog might collapse after a long day of herding or hunting.

After hiking twelve miles in the heat, I was dog tired and went straight to bed.

The phrase is informal but widely used across English-speaking regions.
