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.
Also, the time that a puppy reaches sexual maturity and is capable of reproducing is often considered to be a pivotal age point, but again, sexual maturity does not mean that any given dog should be considered an adult, and they will almost certainly have a lot of growing and maturing left to do.
