How long does a french bulldog stay on heat for?

A French Bulldog typically stays in heat for about 2 to 3 weeks. The heat cycle, or estrus, occurs approximately twice a year and includes several phases. During this time, the female may exhibit physical and behavioral changes, such as swelling of the vulva and increased urination. It's important to monitor her closely and consult a veterinarian for guidance on care during this period.
