Dogs are usually in heat for 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, but this time can be longer as dogs are indviduals. Female dogs first go into heat at puberty which can be any time between 6-12 months.
ahahahahaha! I don't know if you intentionally misunderstood, or if you actually don't know--when a dog is fertile, it's called being "in heat." Either way, I'm voting you up! add a comment
