Is Dudley adopted?

Does anyone else suspect that Dudley Dursley might be adopted?  I 
think this might explain why the Dursley's have always spoilt him so 
much and why they don't have any other children.

There is also the issue of Harry's blood protection.  This protection 
really does seem to be limited to Petunia because it sure as heck 
didn't work in the alleyway when the Dementor's attacked Harry.  If 
Dudley really was his blood relative then surely Harry should have 
been protected?

In GoF Voldemort says that the ancient magic that protects Harry 
means that not even he can touch him at Privet Drive.  So if 
Voldemort can't touch Harry how come the Dementor's could?  In OoP 
Dumbledore says Lily's blood flows on in her sister - her only living 
relative.  This is telling IMO.

I don't think Petunia is Dudley's biological mother and that my 
friends, opens up a million other possibilities that I will get into 
at another time.

What do you think?
