Heat Cycle

Question
My question is after the first time the dog gets in heat when will it happen again? So, I can be aware and keep her from getting with any dog.

Answer
Hello Roselda, in approximately 6 month You may notice a slight swelling of the vulva for approx. 3 days then bleeding for approx. 7 days,  she will stop bleeding and is able to get pregnant at this time for appox. 7 days and then it's another 7 days going out when the vulva will begin to go back to normal size.  So it's a 21 day cycle.  7 going in...7 in ... and 7 going out.  And in 6 months it will come again. I hope this helps. Thanks for asking, Cindy Lou :)
