Unless you are a reputable breeder, your dog probably shouldn't be bred. Please study under a reputable breeder before you even think about breeding. Your dog should be of impeccable breeding to begin with and have correct confirmation through several dog shows to attain titles. But in general, the dog will be in heat for an average of 3 weeks. For the first 7 - 10 days, the dog will bleed and then she will be ready to mate for about 1 - 7 days depending on the dog and then she will bleed again for a few days after.
