Sex

Typically, between the ages of 6 and 12 months, Bouvier des Flandres dogs reach sexual maturity, or puberty. While most dogs achieve full maturity around the same period, bigger breeds like Bouviers often take a little longer than smaller dogs.

Estrus, sometimes known as "heat," begins at a female Bouvier's sexual maturity and continues for around 6 to 9 months (though this might vary). Between six and twelve months of age is when most babies start their first heat cycle. Vulva enlargement, vaginal discharge, and behavioral changes are all signs that a female is ready to mate during estrus.

A female Bouvier will change her smell, become more sociable with males, and be more likely to stand for mating when she is in heat. These cues indicate that she is ready to mate, and male Bouviers, who are good at reading these cues, may show more desire to reproduce.

At around 6 to 12 months of age, when they achieve sexual maturity, male Bouviers are able to start reproducing. On the other hand, you should probably hold off on breeding them until they're all grown up, both emotionally and physically.

Although female Bouviers may go through their first heat cycle anywhere from six months to a year, the general consensus is that you should wait until they've had two or three cycles before thinking about mating them. The females are better prepared for the challenges of pregnancy and parenthood since this delay gives them time to reach full maturity.
