The best supernatural Horror film of this decade is a matter of opinion. Since it's only 2013, there are still 7 more years to decide what was the best movie of that type was made for the decade.
Depends how you define Horror. It's not horror in the supernatural sense (ghosts, vampires, living dead) It's a psychological "warped person" film, a bit like Psycho, or Misery.
For the most part, the quintessential horror film with a dog in it was the film "Cujo".
Film critics consider Paul Thomas Anderson's "There Will Be Blood" to be the best movie of the decade.
That's a matter of opinion. I don't think it's "the Best" horror film. If you believe it is, good for you.
