Generally it is around 6 months old. Some dogs don't go into heat until they are passed a year old. Never breed your dog on a first heat. Research before breeding. Find a mentor, but don't just breed her. She will be in heat for at least 21 days. Continue keeping her away from other dogs though until you are absolutely sure she is no longer in heat. I have a dog that stays in heat 5 weeks minimum! She's always been that way.
