Our dog being more citizen than canine
Does not know that he's a dog,
Ignores the virtue of humility in his doggy world
Being profoundly loved by adult and child there.

If by some grace wisdom ever comes to him
He will learn a simple truth
It is not wise for small dogs to growl at big
Lest intercepting the greater's trajectory
They become the object of both their attention and their teeth.
