Yes this is absolutely normal.
Dogs go into heat at any time between 6-12 months usually.
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.
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.
You have to keep them away from males the entire heat cycle to avoid pregnancy. Do not rely on 'panties' or short barriers to keep male and female apart and don't let her run off leash unless supervised in a securely fenced yard as she is as interested in the boys as they are in her.
Hope this helps you!
