Use of a Dog

It brings a tear to the eye

To see the kind of trust

That bears many strains

It brings a smile

To see trust that believes many things

Who would question the worth of a dog?

Who would query the use of a dog?

Fidelity is a fine attribute

Loyalty to his master is never in dispute

Watchfulness is a valuable trait

Here's a fellow who looks left and right to cross the street

Who would question the worth of a dog?

Who would query the use?
