Maybe next there will be a first-hand account about their dog's trip to heaven to help verify the little boy's story. It seems there are some people here who need something to latch onto.
Nah.. If the dad is smart, he'll make this a trilogy in four parts. Next will be the younger sister and then part 3 will be about the dog going to heaven and going "woof, woof, dog darn it, the little excrescence was telling the truth" and then the dog comes back and tells his master "woof, woof, hau, hau, grrr,grrr" and the master translates it to describe all the splendors of heaven
Part 4 will be the magnum opus when Jesse Duplantis or Benny Hinn come to visit the family and listen to the dog speak and then they get a whole new revelation by reading between the Woof-Woofs.
Once that is done, they can re-release the first 3 with additional excerpts of the little kid playing ball with the cherubs and the dog learning that in heaven he's not allowed to scent-mark the trees.
There must be some way to get Vogons into this story.
