Dumbledore can be alive, if you squint just right (long)

Peter Petigrew (Wormtail) is dead and Dumbledore is not.

DD is PP and PP is DD.  Basically Dumbledore has taken control of PP
and PP has the guise of Dumbledore using the polyjuice potion. 
Dumbledore also masquerades as PP using polyjuice potion.

   One of the 10 uses of dragon's blood is to fortify a potion, to
increase it's affect, to lengthen it's duration.
   Dragon's blood makes Polyjuice Potion last much longer, perhaps
until a counter potion is taken.  

   
HBP Chapter 3

  (Polyjuice does not work correctly on PP's magically created silver
hand.)

   As he placed his wand in his pocket, Harry saw that his hand was
blackened and shriveled; it looked as though his flesh had been burned
away."

HBP Chapter 4

    (Dumbledore is the spider.  PP (Wormtail) is polyjuiced to look
like Dumbledore.)

    Harry nodded, his eyes fixed resolutely on the spider now climbing
Dumbledore's hat.
    ...

   "Yes," said Harry again, "And now everyone knows that I'm the one"
  "No, they do not," interrupted Dumbledore.  "There are only two
people in the whole world who know the full contents of the prophecy
made about you and Lord Voldemort, and they are both standing in this
smelly, spidery broom shed."

HBP Chapter 20

    (A bottle contains Dumbledore's memory as he could not take it
from PP polyjuiced as himself.)

    "However, I have two last memories that I would like to share with
you." Dumbledore indicated the two little crystal bottles gleaming
beside the Pnsieve.
...
   Harry got to his feet once more as Dumbledore emptied the last
memory into the Pensieve.  "Whose memory is it?" he asked. "Mine,"
said Dumbledore. 

HBP Chapter 26

    (DD requires HP to give his word as under physical duress DD's
control over PP slips.
    As the pain increases DD control over PP wanes and PP pleads for
relief.  Later in delerium PP relives a similar painful event
involving Voldemort.)

    "Once and for all, Harry, do I have your word that you will do all
in your power to make me keep drinking?" ...
    "I - all right, but -"

     "I don't want... Don't make me..."

     "...don't like...want to stop..."

    "No..."

    "I don't want to...I don't want to...Let me go..."

    "Make it stop.  Make it stop"

    "No, no, no, no, I can't, I can't, don't make me.  I don't want to..."

    "It's all my fault, all my fault," he sobbed. "Please make it
stop, I know I did wrong, oh please make it stop and I'll never, never
again..."

    "Don't hurt them, don't hurt them, please, please, it's my fault,
hurt me instead..."

    "Please, please,please, no...not that, not that, I'll do anything..."

    "No more, please, no more..."

    "I want to die!  I want to die!  Make it stop,  make it stop, I
want to die."

    "KILL ME!"

    
The cave was practice for HP.  DD wants HP to look for the Horcruxs.
DD knows that LV will "see" what HP is doing and as the polyjuced PP
he can learn from LV their locations.
