German Shepherd breeding cycle

Question
How can I tell is she is in heat and ready for breeding? She's 18 months old.How often does he come into heat or often is the breeding cycle?

Answer
Hi,  A dog comes into heat normally every 6 months.  A dog's heat cycle breaks done into 3 segments basically once they do come into heat. The 1st 7-10 days, they tend to bleed heavier and will not accept a male, the 2nd 7-10 day segment their vulva will swell and they will be willing to accept a male. The last segment also will last approx. 7-10 days and they will be going out of heat and not accept a male.   Hope this helps,
