If you’re a dog owner, you might be wondering, “how often do dogs get their period?” The answer is that it varies depending on the breed and size of your dog. In general, dogs get their period twice a year, with each cycle lasting for around 21 days. However, small dogs may experience their period more frequently, whereas large dogs may experience their period less frequently.
As a responsible dog owner, it’s essential to understand your furry friend’s menstrual cycle. Dogs, like humans, experience a menstrual cycle that has its own unique stages and frequency. In this article, we will provide a comprehensive guide to understanding how often dogs get their period, as well as the signs to look out for and how to manage it.
How often do dogs get their period: A Comprehensive Guide
- A dog’s menstrual cycle has 4 stages: Proestrus, Estrus, Diestrus, and Anestrus.
- The frequency of a dog’s period varies based on breed, size, and other factors.
- Managing a dog’s period involves hygiene tips, exercise and dietary changes, and products to help with management.

Stages of a Dog’s Menstrual Cycle
The cycle is divided into four stages: proestrus, estrus, diestrus, and anestrus.
Proestrus
The proestrus stage is the first stage of a dog’s menstrual cycle and lasts for around 9 days. During this stage, the dog’s body prepares for mating. The dog’s vulva swells, and she may experience a bloody discharge.
Estrus
The estrus stage is the second stage of the menstrual cycle and lasts for around 9 days. During this stage, the dog is receptive to mating and may display signs of attraction towards male dogs. The bloody discharge may become lighter than the proestrus stage.
Diestrus
The diestrus stage is the third stage of the menstrual cycle and lasts for around 60 days. During this stage, the dog’s body prepares for pregnancy. If the dog has not become pregnant, she will experience a false pregnancy.
Anestrus
The anestrus stage is the final stage of the menstrual cycle and lasts for around 120 days. During this stage, the dog’s reproductive system is dormant, and she will not experience any hormonal changes.

Signs of a Dog’s Period
During a dog’s period, she may display changes in behavior and physical changes.
Physical Changes
Physical changes that occur during a dog’s period include swelling of the vulva, bloody discharge, and changes in the color and consistency of the discharge.
Behavioral Changes
During a dog’s period, she may display changes in behavior, such as restlessness, increased urination, and aggression. It is important to monitor your dog’s behavior during her period and ensure that she is comfortable.

Managing a Dog’s Period
To manage your dog’s period effectively, it is important to maintain good hygiene, provide exercise, and feed a balanced and nutritious diet.
Hygiene Tips and Advice
This includes regularly cleaning your dog’s genital area and providing her with a clean and comfortable sleeping area.
Exercise and Dietary Changes
Regular exercise can help reduce stress levels, which can affect a dog’s menstrual cycle. Feeding your dog a balanced and nutritious diet can also help regulate her menstrual cycle.
Products That Can Help Manage a Dog’s Period

Potential Health Concerns
During a dog’s menstrual cycle, she may be more susceptible to infections, such as uterine infections. Female dogs that have not been spayed may be at risk of developing tumors or other reproductive issues. Other health concerns that may arise during a dog’s menstrual cycle include anemia, which can occur due to blood loss, and pyometra, which is a potentially life-threatening uterine infection.
Conclusion
Case Study: Understanding the Importance of Monitoring a Dog’s Menstrual Cycle
As a dog owner, I have always been vigilant about my dog’s health and well-being. However, I learned the hard way how important it is to monitor a dog’s menstrual cycle.
Last year, my dog Bella, a 4-year-old Golden Retriever, started to show signs of lethargy and loss of appetite. Initially, I thought it was just a phase, but when she didn’t improve after a few days, I took her to the vet.
After a thorough examination, the vet discovered that Bella had a pyometra, which is a bacterial infection of the uterus that can occur during a dog’s menstrual cycle. The vet explained that if I had not brought her in when I did, the infection could have spread, leading to a more serious condition or even death.
This experience taught me the importance of understanding and monitoring a dog’s menstrual cycle. Since then, I have been more diligent about keeping track of Bella’s menstrual cycle and ensuring that she receives proper care during this time.
I urge all dog owners to pay close attention to their dog’s menstrual cycle and to seek veterinary care if they notice any unusual symptoms or behaviors. It could make all the difference in your dog’s health and well-being.
Understanding a dog’s menstrual cycle is essential for their reproductive health and overall well-being. The menstrual cycle is divided into four stages: proestrus, estrus, diestrus, and anestrus. The frequency of a dog’s menstrual cycle varies depending on breed and size. As a responsible dog owner, it is essential to prioritize your dog’s menstrual cycle management. This includes maintaining good hygiene, monitoring her behavior and health, and seeking veterinary attention if necessary. By following these steps, you can ensure that your furry friend remains healthy and happy.
