French Bulldog Heat Cycle

French Bulldog Heat Cycle

It can be messy and worrying too; particularly if you’ve not had a female dog before. If you’ve ever wondered how many times a year a French Bulldog goes into heat, what the signs are, how long they bleed, and how long the heat cycle lasts, then this guide will be the perfect primer for you.


How often do French Bulldogs go into heat?

French Bulldogs tend to go into heat twice per year, roughly every 6 months. The overall heat cycle lasts for several weeks and is a time period when she’s receptive to breeding.

French Bulldogs reach sexual maturity between 6 and 9 months of age, which is when the female will generally have her first heat cycle. Some will then start to cycle every 6 months if left un-spayed, while others may take 1 to 2 years to develop a regular cycle and will cycle irregularly until that time.

At the same time, she may urinate more frequently than usual, which is a way to mark and signal to other dogs that she’s in heat.

Behaviorally, your Frenchie may see distracted or even nervous.

She may start to mount other dogs or even your leg, or she may allow herself to be mounted. Eventually in her heat cycle, she’ll become receptive to males.

How long does a French bulldog bleed in heat? 

The start of the heat cycle is a period known as PROESTRUS, which lasts for 4 to 20 days and is characterized by a vaginal discharge and males being attracted to the female, but the female is unwilling to mate.

While bleeding occurs before a female tends to be able to be bred, males are often attracted to the female by the start of PROESTRUS

The next period is ESTRUS, which lasts for 5 to 13 days. This is when the female can get pregnant. The vulva is swollen, the vaginal discharge becomes yellowish and watery in color, and mating occurs.

The most likely time for females to be bred are when their vaginal discharge turns watery. The sperm can live in the reproductive tract for up to a week though, so your female can actually get pregnant during just about any time in ESTRUS.

DIESTRUS is the period after ESTRUS or mating and lasts for 60 to 90 days. If the female is pregnant, the cycle will last right about 63 days.

ANESTRUS is another long period in the cycle. It is considered a period of inactivity between estrus phases and lasts for 2 to 3 months before proestrus begins again.
