Actually, there are organizations already set up that help the Afghani street dogs. I Googled and found 'em.
Don'tcha just love the interwebz?
Mayhew International and Nowzad Dogs are in affiliation to care for and keep these animals safe. Some dogs are even sent to the U.S. To be reunited with their military buddies.
So I'm thinking more and more this "Save Spike" website is a scam to bilk kind hearted people out of money.
