Expert: Jane Lefler replied 8 years ago. HiCustomer. 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.
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
