A heat cycle for female dogs last 21 days, thats 3 weeks. The first week the are coming in heat, the second week is when you got to be careful, this is when they are ready to be bred, the third week they are coming out of heat. Usually the dog is ready to be bred by 9 days after the first start bleeding. So to answer your question, the second week is when they will let the male breed with them.
Watch them real carefully and a diaper will NOT prevent her from getting pregnant. You need to completely seperate them and put them in to separate rooms. This is best anyways since the first week and third week, your female is likely to hurt your male as she will snap or bite him for trying to breed with her. |
