It is recommended that you breed your pit bull when it is in its second heat, as it is only sexually mature in its first heat and only reaches physical maturity in its second heat. Mating and breeding at this time will cause very little physical damage. When looking for a breeding partner for a French bulldog, be careful to choose a dog of the opposite sex that is about the same size and has obvious heat and mating experience, and you need to avoid a female that cannot handle the weight of a male. Before mating, you can let them live together for a few days to get acquainted with each other. Generally female French bulldogs start ovulating around the 11th day after they come into heat, and this is when they are ready to mate.
