A few key things is that the female needs to be in the right stage of heat and also needs to be brought into the males territory for mating and not the other way around. Male dogs become sexually mature around 6-7 months of age so he is old enough. To breed successfully you need to understand the heat cycle. I have explained it below and included a site that has a pictorial guide so there is no mistake what stage of heat your girl is in.
Half of male dogs will display mounting behavior by 5Â½ months of age, and will become able to sire a litter around that age. Note that some male dogs may be able to sire a litter before 5 months of age - 5 months is the average. Female dogs become sexually mature (have their first heat) between 5 and 12 months of age.Small breed dogs tend to have their first heat around 5-6 months, while some giant breed dogs will not start to cycle until they are 18-24 months of age.Although most dogs are sexually mature by one year of age, dogs should not be used for breeding until they are at least 2 years of age.ote that some male dogs may be able to sire a litter before 5 months of age - 5 months is the average.
