The estrous (or heat) cycle of a female French Bulldog typically lasts between 21 and 28 days. During this time, your dog will undergo a variety of hormonal changes as well as physical signs that indicate that she is in heat. Knowing how long your French Bulldog will be in heat can help you to make appropriate decisions about breeding or other activities that involve interaction with other dogs.

The Estrous Cycle
The estrous cycle of the French Bulldog is the reproductive cycle of female dogs that involves the production of hormones which regulate the regular shedding of eggs and allow for successful breeding. The cycle typically begins with the first signs of heat and continues on for 21-28 days, depending on the individual dog. During this time, your French Bulldog may show certain physical signs that make it easy to detect when she is in heat. These can include:
- Swollen Vulva: A swollen vulva is one of the most telling physical signs that your dog is in heat. As the hormones are released in your dog’s body, the vulva may swell and become more prominent.
- Vaginal Discharge: You may also notice a vaginal discharge from your dog’s vulva that is either a pinkish or bloody colour. This discharge is a sign that your Frenchie’s body is preparing for a potential pregnancy.
- Behavioural Changes: During this period, your French Bulldog may also display increased levels of energy and may behave differently than usual. She may also try to escape and explore in search of a potential mate.
The Heat Cycle Length
The length of the heat cycle in a French Bulldog can vary between dogs, but typically ranges between 21-28 days. This is divided into four stages which each have their own associated behaviours and physical signs:
Proestrus Stage (1-7 days)
During this stage, your French Bulldog may have a swollen vulva and a milky discharge will be present; however, she will still be uninterested in breeding. Your dog may also start displaying certain behavioural signs such as lifting her leg when urinating, which can indicate her readiness to breed.
Estrus Stage (7-14 days)
During the estrus stage, your French Bulldog may become more receptive to male attention, and may start to flirt with potential mates. The vulva will still be swollen and the discharge will now be a pinkish or bloody colour. This is the part of the cycle when mating is most likely to occur, however, it is still not guaranteed that your dog will become pregnant.
Diestrus Stage (14-21 days)
If your French Bulldog was successfully bred during the estrus stage, she will now enter the diestrus stage, which is the stage when sperm and eggs meet and a potential pregnancy may occur. During this stage, your dog may show less interest in males and her level of energy may be lower than normal.
Anestrus Stage (21-28 days)
During the anestrus stage, the hormone levels of your French Bulldog will start to return to normal and she will no longer show any signs of being in heat. This is the end of the cycle and the beginning of the waiting period; if your dog is pregnant, you will know within the following 6-8 weeks.
The heat cycle of the French Bulldog typically lasts 21-28 days, depending on the individual dog. During this period, your Frenchie will show certain physical and behavioural signs that indicate she is in heat, such as swollen vulva, a pinkish/bloody discharge, and increased energy levels. Understanding the length of the cycle can help you to make appropriate decisions with regards to breeding or other activities that involve interaction with other dogs.
In conclusion, it is important to keep an eye on your French Bulldog during her heat cycle and be aware of the changes she goes through. Knowing the length of the cycle can help you to prepare for potential breeding, or to avoid situations where your dog may encounter other male dogs. Ultimately, regular visits to the vet can help to ensure your Frenchie’s reproductive health is in good shape.
