I have used chicken broth to get my dam to drink or even puppy milk watered down for now.
try a flea collar
You can take a puppy to water, but you cannot force it to drink.
Like kiteman says - they are genetically programmed not to starve or dehydrate. If its a substancially long time, take them to the vet, they're sick - otherwise they're just picky. Also - try keeping them around mom while she's drinking. It can be a learned action.
They will soon get the urge when they get thirsty.
