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.
Below is a guideline for the age at which breeds tend to reach sexual maturity: Miniature breeds: Netherland Dwarf, Dwarf Hotot, Polish, Britannia Petite, Holland Lop, and other similar breeds. Reach sexually maturity at 125 to 150 days of age.edium breeds: Florida White, Dutch, Mini Lop, Havana and other similar breeds Reach sexually maturity at 150 to 180 days of age. Large breeds (Commercial or Standard breeds): New Zealand, Californian, Champagne dâ Argent, Palomino and other similarly sized breeds Reach sexually maturity at six to seven months of age.
