Dogs go into heat at any time between 6-12 months usually and it varies dog to dog when they come in. While eight months is a common time you can't rely on that being the case with your dog.
Typical signs of heat coming on include the vulva swelling, a red discharge, the dog licking herself a lot, more frequent need to urinate, urinating when she sees another dog, the nipples may become more obvious too.
Dogs are normally in heat about 3 weeks. The first week they have a red discharge then the second a clear or straw colored discharge then almost no discharge the last week. They usually breed sometime in the middle of their heat usually in the range of 9-14 days of their heat season. They are not normally bred until their third heat to make sure they are mature in body and mind before having to raise pups of their own. Usually they come in heat every 6 months after the first heat.
Gestation lasts 58-65 days with 63 days or 9 weeks from the first breeding being about average.
Hope this helps you!
