My version of this one 
To the tune of HOW MUCH IS THAT DOGGY IN THE WINDOW?
Dad's buying a puppy for the White House (woof, woof)
It's one with a waggly tail
Dad's buying a puppy for the White House (woof, woof)
The problem is I am quite frail
Dad's buying a puppy for the White House
It must be a real special breed
The dog must be hy-po-allergenic
Cos if not it will make me sneeze (‘achoo!)
Dad's taken a trip to California
To meet Arnold Schwarzeneggar
He's off'ring a place as an advisor
Maybe he'll suggest a Schnauser
Dad's buying a puppy for the White House (woof, woof)
I hope that it will be well trained
Clinton once had a doggy in his office (oh, oh)
And Monica's dress was left stained
I read in the papers there are bad men
Who want to make my Dad's life hard
If we can get it some dark glasses
The dog can be a bo-dy-guard
I don't want an Afghan or a Spaniel
I don't want one with woolly hair
I don't want one that-triggers a reaction
Like-the-pet George Bush called Tony Blair
Dad's buying a puppy for the White House (woof, woof)
He told me that I must now learn
A dog's not for Christmas or my birthday
It must last his Pres-id-ent-ial term
