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.
Reproduction in dogs - season, heat, oestrus, pregnancy tests. Puberty or sexual maturity in the female dog usually occurs around six months of age. The smaller breeds tend to go into oestrus or heat earlier and some females can have their first heat cycle as early as four months of age. On the other hand, the large and giant breeds can be up to two years old before they come into heat for the first time.
