Dogs and fleas, they go together
In pleasant or inclement weather.
Take a lovely day in spring
When butterflies are on the wing.
An ordinary kind of dog
Has spied an ordinary frog.
To dog, this creature's something new
He sniffs its back, as dogs will do.
The frog is calm as calm can be
It is as if he doesn't see
This curious nose upon his back
This nose so bulbous, wet, and black.
And while these two are occupied
A flea decides to hitch a ride...

The flea's adventures continue in A Flea's Tale,
a juvenile rhyming picture book (34 pages, including 17 illustrations).
