As close to the first heat as possible, without spaying during a heat.
If you can keep your dog from getting pregnant and are OK with waiting, I actually think waiting until after the first heat might be better. It allows a bit more time for growth, and only increases the risk of mammary cancer by a small margin. If you don't want to deal with a 21 day doggie period, get it done before the first heat and reduce the risk of mammary cancer by 97%.
