Do Dogs Have Periods?
Unlike humans, dogs do not have menstrual cycles where they shed the lining of their uterus and experience bleeding. Instead, they undergo an estrous cycle, which involves four distinct phases: proestrus, estrus, diestrus, and anestrus.
Signs of a Dog's Estrus Cycle
Proestrus
- Duration: Approximately 9 days
- Signs:
- Vulva swelling and bleeding
- Attraction to males
- Increased urination
Estrus
- Duration: Approximately 9 days
- Signs:
- Peak fertility
- Vulva bleeding subsides
- Receptive to mating
Diestrus
- Duration: Approximately 60 days
- Signs:
- No bleeding or swelling
- Decreased interest in males
- Uterus prepares for pregnancy
Anestrus
- Duration: Approximately 90 days
- Signs:
- No reproductive activity
- Uterus is inactive
Health Implications of a Dog's Estrus Cycle
During the estrous cycle, dogs are more likely to experience certain health issues, including:
- Pyometra: Infection of the uterus
- Ovarian cysts: Fluid-filled sacs on the ovaries
- Mammary gland tumors: Cancerous or non-cancerous growths on the mammary glands
Regular veterinary checkups and spaying (surgical removal of the uterus and ovaries) can help prevent these potential health problems.

FAQ about Dogs Having Periods
Do dogs have periods?
Answer: No, dogs do not have periods like humans. Female dogs experience "heat" or "estrus" cycles instead.
What is heat or estrus in dogs?
Answer: Heat is a period when a female dog is fertile and receptive to mating. It typically occurs every 6-12 months and lasts for about 3 weeks.
What are the signs of heat in dogs?
Answer: Signs of heat include a swollen vulva, bloody discharge, increased urination, and a receptive attitude towards males.
How long does the heat cycle last?
Answer: The heat cycle typically lasts for 18-21 days, with the fertile period occurring between days 9 and 15.
What happens if my dog is not bred during heat?
Answer: If your dog is not bred, her body will naturally reabsorb the eggs after about 2 months.
What is a false pregnancy?
Answer: A false pregnancy can occur in dogs that have been bred but do not become pregnant. It is characterized by similar symptoms to pregnancy, such as swollen abdomen, milk production, and nest-building behavior.
Can my dog get pregnant if she is not in heat?
Answer: It is very unlikely for a dog to get pregnant if she is not in heat. However, it is still possible if she has had recent exposure to a male dog during her previous heat cycle.
What is pyometra?
Answer: Pyometra is a serious infection of the uterus that can occur in dogs that have not been bred or have gone through a false pregnancy. It is a medical emergency and requires immediate veterinary attention.
How can I prevent my dog from getting pregnant?
Answer: The most effective way to prevent pregnancy is to spay your dog (remove her uterus and ovaries). Other methods include using birth control pills or having your dog bred under controlled conditions.
What should I do if I suspect my dog is in heat?
Answer: If you suspect your dog is in heat, it is important to keep her away from male dogs and monitor her closely. Contact your veterinarian if you have any concerns or if her symptoms worsen.
If your dog has an unusual discharge, make sure that a veterinarian checks it out. A veterinarian can determine whether this is a natural discharge or an infection.
