Analysis of My dog barks incessantly through the night

my dog
barks incessantly
through the night
at ghouls and ghost
only a dog's eye can sight
for I swear
when I look
there's nothing to be seen

he barks at the wind
the trees and
all in between

he barks at me
when I come to see
what has him acting
so strangely

he barks at shadows
cast by the moon
a shadow of his tail
has him all swooned

he barks at cars  noise and
strangers in the night
he barks at every little thing
that cause him fright

he barks at the neighbors cat
at the neighbors fence
he sits and dispense
of barking
until spent

breaths
lap water
then barks again

he barks a melody
that's well received
it seems

for out of the night
the howling begins
dogs and cats alike

they bark at the moon
they bark at each other
they bark at
whatever
gives them pleasure
