Understanding Canine Estrous Cycle
You may have noticed that your female dog behaves differently at certain times. This is because, like humans, female dogs also have reproductive cycles, often referred to as a “dog’s period.” However, it’s not the same as a human menstrual cycle. Instead, it’s called the estrous cycle.
The Stages of a Dog’s Estrous Cycle
During a dog’s life, she will go through different stages of the estrous cycle. Knowing these stages can help you better understand and care for your pet.
- Proestrus: This is the beginning stage of the cycle, lasting about 9-10 days. You’ll notice your dog’s vulva swelling and some bloody discharge.
- Estrus: This stage lasts 9-10 days and is when your dog is ready to mate. The discharge will be lighter, almost straw-colored.
- Diestrus: The diestrus stage is when your dog is no longer interested in mating. It will last about 6-10 weeks.
- Anestrus: This is the final stage of the cycle, and it’s a period of sexual inactivity. It usually lasts 4-5 months.
| Stage | Duration | Symptoms |
|---|---|---|
| Proestrus | 9-10 days | Swelling vulva, bloody discharge |
| Estrus | 9-10 days | Lighter discharge, ready to mate |
| Diestrus | 6-10 weeks | No interest in mating |
| Anestrus | 4-5 months | Sexual inactivity |
How Often Do Dogs Get Their Period?
Unlike human females who go through a menstrual cycle every month, dogs’ estrous cycle is less frequent. Most dogs come into heat twice a year, but the frequency can vary depending on the breed and individual dog. Small breed dogs can have cycles three times a year, while larger breed dogs may only have a cycle once a year.
Caring for a Dog in Heat
When your dog is in heat, she will require more care and attention from you. Here are some tips to help you:
- Keep your dog indoors to prevent unwanted pregnancies and protect her from male dogs.
- Use special doggie pants or pads to manage the discharge.
- Give your dog extra attention and care as she may be feeling uncomfortable.
FAQs
Q1: How can I tell if my dog is in heat?

Q2: Is it safe for my dog to mate during her first heat?
A2: It’s generally recommended to wait until your dog is at least two years old before breeding.
Q3: Should I spay my dog to stop her periods?
A3: Spaying is a personal decision. It does stop the heat cycle and can prevent certain health issues, but it also has potential risks and side effects. Consult with your vet to make the best choice for your pet.
