I need help with picking a name for my new puppy?

He looks like a golden retreiver but he is a chiuahua mixed with a poodle. Anyways I have been thinking of mostly greek god names, but it doesn't have to be. These are the names I have thought of so far: ace, comet, apollo, hermes, lucky, achilles, posiden, zeus, astro or ziggy. Which one of these do you like? Or feel free to think of another greek god/monster/etc.
