Buy a copy of 'The Book of the Bitch' by White and Evans. It'll answer all your questions, as well as many you didn't think to ask!
In the meantime, keep her away from
all other dogs for at least 21 days, probably 28 is safer. That means not letting her out of doors unsupervised, even in your own garden. Don't walk her when or where you're likely to meet other dogs. Apart from that, treat her as normal, though as she's on restricted exercise you will probably have to cut her food intake to compensate.
