Mutated dog

He has two heads and he has three legs
He has no tail what a crying shame
There is nothing for him to wag
to let us know that he's happy
Is he rabid? no.
Is he rabid? no.
Hey, I ought to know
Is he playful? yes.
Is he playful? yes.
Or would you rather guess?
Eats pitbulls for breakfast
Eats pitbulls for breakfast
and swallows them whole
Mutated dog is my best friend
He ate the teacher and the teacher's pet
While running loose in the backyard
he feeds on little kiddies arms
He's my mutated dog
He's really mean no harm.
