"Why dogs stopped flying", by Kenneth Brewer

Before humans,
dogs flew everywhere.
Their wings of silky fur
wrapped hollow bones.
Their tails wagged
like rudders through wind,
their stomachs bare
to the sullen earth.
Out of sorrow
for the first humans--
stumbling, crawling,
helpless and cold--
dogs folded their
great wings into paws
soft enough to walk
beside us forever.
They still weep for us,
pity our small noses,
our unfortunate eyes,
our dull teeth.
They lick our faces clean,
keep us warm at night.
Sometimes they remember flying
and bite our ugly hands.
