A dog´s work.

The dog´s barking, I wonder what he think´s he´s saying?
The gate rattles there the neighbour´s kid playing.
The dog turns, his expression says to me maybe they haven´t heard me.
Someone yells at the bottom of the drive, everyones too lazy to go see.
Now off the dog goes again barking and jumping to see over the gate.
A humm roars into the sound of a car rolling up for someone who waits.
The dog turns to me again with that look while on his guard-"So you think your job´s hard?"
