Why Walk a Dog?

Why does a dog need to be walked
Three birds fighting out in the yard
But I dont know what theyre fighting about
So why does a dog need to listen
Whenever you shout

These cats seem to blow
Everyones mind but mine
What is so funny
About beasts above understanding

Are you their master
Did you buy them at the store
Did they know they were a cure
For you to stop being bored

So somebody mated them
And took their babies away from them
Stuck a price tag on their nose
And now youre buying it clothes
So why does a dog need to be walked
