Why do dogs sniff each other?

The dogs once held a meeting; they came from near and far.

Some of them came by train, and others by trolley car.

 

But before they got inside the hall and allowed to take a look,

They had to take their rear ends off and hang them on a hook.

 

Then in the hall they went at once... the Mother, son and sire.

But hardly were they seated when some "mongrel" hollared "FIRE!"

 

So out the door they ran all in a bunch... they had not time to look...

And each one took a rear-end, at random, from the hook.

 

They got their rear-ends all mixed up, which made them awful sore.

To think they didn't have the one they'd always had before.

 

And that's the reason you will see, when you go down the street,

Each dog will stop to swap a smell with every dog they meet.

 

And that's the reason why a dog will leave a nice fat bone.

To go and smell a rear-end ... 'cause he hopes to find his own!
