Talking Dogs

A pig says "oink";
That's all he'll say
And every horse
Knows only "neigh."
Consider ducks
Who "quack" each day
Or cows as well,
On "moo" they'll stay.

But dogs have depth,
A repertoire,
Myriad ways
To speak with pow'r.
Dogs "bow wow;"
They "arf" and "bark."
They often "howl."
When it gets dark.
Dogs, at times
As is their wont,
"Growl" at folks
A canine taunt.
Finally, when
Contentment's here,
Dogs say "woof"
And scratch their ear.
