Alright, I have scoured the net and found several versions of this story.

In some stories, the puppy was given to them as a gift by the aunt THREE weeks before the incedent.

Apparently when he was hit by a truck, he was walking home with his older brother. This happened over a year ago, and the doctors said that he'd fully recover from the accident. So why is he paralyzed???

I've seen several spelling/grammar mistakes in most of the stories I read. It could be that this story was severely altered in it's legitimatcy. Or it could be like the Macdonalds story.
