Do all dogs go to heaven?

That's the question in my book today. Cosh, the blackjack terrier, thinks they do. Gabriel, the angel but not the Gabriel, is not so sure. He's wondering what happens to the dogs that eat little children. I'm thinking specifically of an attack by three dogs on a woman walking with her daughter. When the pack attacked she put her daughter up on her shoulders but the dogs mauled both of them. Do those dogs deserve to go to heaven?
