The Dogue de Bordeaux reaches sexual maturity and becomes fertile at a certain age. Dogue de Bordeaux puppies often reach sexual maturity anywhere from six months to a year of age, however, this may vary from dog to dog. Sexual maturity isn't always a sign that it's the best time to have a family, however.

A dog's health, temperament, and general welfare are just a few of the aspects that must be carefully considered while breeding responsibly. Veterinarians and breeders generally agree that dogs shouldn't be bred until they are 18 to 24 months old. As a result, the dog is able to avoid the health problems that might arise from having puppies too young.

If a dog owner is thinking of breeding a Dogue de Bordeaux, they must be very careful. When breeding dogs, it's important to make sure the male and female are in good condition and that the primary goal is to improve the breed. Finding good homes for the pups and making sure they get good medical care are also important parts of ethical breeding.

Ask your vet or a professional breeder for advice on when and how to breed your Dogue de Bordeaux if you're thinking about doing so.
