A little dog that wags his tail

A little Dog that wags his tail
And knows no other joy
Of such a little Dog am I
Reminded by a Boy

Who gambols all the living Day
Without an earthly cause
Because he is a little Boy
I honestly suppose -

The Cat that in the Corner dwells
Her martial Day forgot
The Mouse but a Tradition now
Of her desireless Lot

Another class remind me
Who neither please nor play
But not to make a "bit of noise"
Beseech each little Boy -
