My Dog Likes to Disco

My doggy likes to disco dance.
He boogies every night.
He dances in his doghouse
till the early morning light.
The other dogs come running
when they hear my doggy swing.
A few will bring play their instruments.
The others dance and sing.
They pair off with their partners
as their tails begin to wag.
They love to do the bunny hop1,
the fox trot2 and the shag.
You'll see the doghouse rockin'
as a hundred dogs or more
all trip the light fantastic
on the doghouse disco floor.
At last, at dawn, they exit
in the early morning breeze,
and stop to sniff3 the fire hydrants,
bushes, lawns and trees.
I just don't understand it
for although it looks like fun.
I can't see how they fit inside
that doghouse built for one.
