Dynamic Duo

Theirs really is the life, two small 
rascally dogs whose affection
for each other is predictable as the
only offspring of a litter. Knowing 
no life other than the one they
pursue with such gusto, rivals and
pals quick to challenge each other
in mad dashes, boxing matches and
wrestling bouts; look-alikes to
onlookers, they are not perfectly
identical since he is lanky and
she full-bodied; she is bold while
he is cautious; he has an elegant
natural grace that eludes her; and
he can leap higher, faster, further
while she hangs back aware of her
limits. To the discerning eye of those
intimately familiar, living with these
binary specimens, character traits
set them apart as does their
individualized facial features and
expressions, so that what they share in
common; mischief, habits and an
unerring sense of timeliness as in:
let's go! let's eat! bed time! gotta go!
only their house companions recognize.
