What can i do with my 8 week old German Shepard Puppy that won't eat?

I recently bought my 8 week old German Shepard Puppy.. It seemed healthy at first and ate the first night but afterwards just didn't eat for two days and today. She's getting rather thin. I don't know what to do. I'm force feeding her milk so far. What could be wrong with her? What can i do to cure her? show more I recently bought my 8 week old German Shepard Puppy..

Update: She won't eat anything. We've feed her diffrent types of dog food. Dry some meat gravy , all the good stuff hoping she'd be interested but denies it all... She drinks alot of water. Should i continue letting her drink alot of water?
