The are usually in heat for 21 days, 3 weeks. Of course, it varies with each dog. First week they will bleed, second week bleeding will decrease and they will start flagging. At this point they are ready to be bred and will accept males. The third week they are going out of heat and will not accept a male and will growl and snap at them. The second week is the week you breed them, the first and third week you can't breed them and they won't accept the male anyway during that time. |
