If you’re a dog owner with an unspayed female, you’ve likely experienced or will soon encounter your dog’s heat cycle.
Also known as the estrus cycle, this natural reproductive phase can be a challenging time for both you and your furry friend.
At Pets Talk, we understand the importance of keeping your dog comfortable, safe, and healthy during this period.
In this guide, we’ll walk you through everything you need to know about dog care during heat, from recognizing the signs to managing behavioral changes and ensuring her well-being. Whether you’re preparing for your dog’s first heat or looking for tips to handle her next cycle, we’ve got you covered!
What Is a Dog’s Heat Cycle?
A dog’s heat cycle is the reproductive phase during which a female dog becomes fertile and can conceive. It typically occurs every 6-12 months, depending on the breed, age, and individual dog. The cycle consists of four stages:
- Proestrus (7-10 days): This is the beginning of the heat cycle, marked by vaginal bleeding and swelling of the vulva. Your dog may attract male dogs but isn’t yet receptive to mating.
- Estrus (5-10 days): The fertile phase, where your dog is receptive to mating. Bleeding may lighten, and she’ll show signs of interest in male dogs.
- Diestrus (60-90 days): The post-fertile phase, where the body either prepares for pregnancy or returns to normal if no mating occurs. False pregnancies can happen during this stage.
- Anestrus (90-150 days): The resting phase between cycles, where the body prepares for the next heat.
Understanding these stages is key to providing the right care at the right time. If you’re unsure when your dog’s next heat cycle will occur, try our Dog Heat Cycle Calculator to predict the dates and plan ahead.
Signs Your Dog Is in Heat
Recognizing the signs of heat is the first step to proper care. Look out for these common indicators:
- Vaginal Bleeding: Light to moderate bloody discharge, which may require dog diapers.
- Swollen Vulva: The vulva may appear larger and more prominent.
- Behavioral Changes: Increased restlessness, clinginess, or aggression. Some dogs may also “flirt” by raising their tail or showing interest in male dogs.
- Frequent Urination: Your dog may mark more often to signal her fertility to male dogs.
- Licking: Excessive licking of the genital area to keep herself clean.
If you notice these signs, it’s time to take extra precautions to keep your dog safe and comfortable.
How to Care for Your Dog During Heat
Caring for a dog in heat requires patience, preparation, and a few adjustments to your routine. Here are our top tips to ensure your dog’s well-being during this time:
1. Manage the Bleeding
The bloody discharge during the proestrus and estrus stages can be messy. To keep your home clean and your dog comfortable:
- Use Dog Diapers or Pants: Invest in reusable or disposable dog diapers designed for heat cycles. Brands like Pet Parents offer comfortable options that fit well.
- Protect Furniture and Bedding: Cover your dog’s favorite spots with washable blankets or towels.
- Clean Regularly: Gently clean your dog’s genital area with a damp cloth to prevent irritation or infection. Avoid harsh soaps, as they can disrupt her natural balance.
2. Prevent Unwanted Pregnancies
During the estrus phase, your dog is fertile and will attract male dogs. If you’re not planning to breed, take these steps to prevent accidental mating:
- Supervise Outdoor Time: Never leave your dog unattended in the yard, even if it’s fenced. Male dogs can be surprisingly determined and may jump fences to reach a female in heat.
- Leash Walks Only: Keep your dog on a leash during walks, and avoid dog parks or areas with off-leash dogs.
- Separate from Male Dogs: If you have an unneutered male dog at home, keep them in separate rooms or crate one of them to prevent mating.
3. Provide Comfort and Reduce Stress
Your dog may feel anxious or uncomfortable during her heat cycle due to hormonal changes. Help her relax with these tips:
- Create a Quiet Space: Set up a cozy, quiet area where your dog can rest without disturbances.
- Offer Extra Affection: Spend quality time with your dog—gentle petting or a calming massage can help ease her stress.
- Use Calming Aids: Products like pheromone diffusers (e.g., Adaptil) or calming treats can help reduce anxiety. Always consult your vet before using new supplements.
4. Adjust Exercise and Activity
While your dog may still need exercise, her energy levels and behavior might change during heat. Here’s how to adapt:
- Short, Controlled Walks: Opt for shorter walks in low-traffic areas to minimize encounters with male dogs.
- Avoid Strenuous Activity: If your dog seems lethargic, don’t push her to overexert herself. Let her rest as needed.
- Mental Stimulation: Keep her mind engaged with indoor activities like puzzle toys or training sessions.
5. Monitor Her Health
Heat cycles can sometimes lead to health issues, especially if your dog isn’t spayed. Keep an eye out for these potential problems:
- Pyometra: A serious uterine infection that can occur in unspayed dogs, especially after a heat cycle. Symptoms include lethargy, fever, increased thirst, and vaginal discharge (beyond normal bleeding). If you suspect pyometra, contact your vet immediately.
- False Pregnancy: Some dogs exhibit signs of pregnancy (e.g., nesting, lactation) even if they didn’t mate. This usually resolves on its own but consult your vet if symptoms persist.
- Irregular Cycles: If your dog’s cycles are too frequent (less than 4 months apart) or absent for over a year, it could indicate a hormonal imbalance. A vet visit can help rule out underlying issues.

Should You Spay Your Dog?
If you don’t plan to breed your dog, spaying (removing the ovaries and uterus) is a highly recommended option. Spaying eliminates heat cycles and offers several health benefits:
- Prevents Unwanted Pregnancies: No more worrying about accidental litters.
- Reduces Health Risks: Spaying significantly lowers the risk of pyometra, mammary cancer, and ovarian or uterine tumors.
- Improves Behavior: Spaying can reduce behaviors like roaming or aggression associated with heat cycles.
The best time to spay is typically before your dog’s first heat (around 6-12 months of age), but it can be done at any age if she’s healthy. Consult your veterinarian to discuss the right timing for your dog. Learn more in our article on Spaying Your Dog.
Tips for Breeders: Preparing for a Heat Cycle
If you’re a breeder planning to mate your dog during her heat cycle, preparation is key to ensuring a healthy pregnancy and litter:
- Confirm Ovulation: The fertile window (estrus) is typically days 9-14 of the cycle, but ovulation timing varies. Work with your vet to perform progesterone testing for precise breeding dates.
- Choose a Healthy Mate: Ensure the male dog is healthy, vaccinated, and free of genetic conditions. A pre-breeding health check for both dogs is essential.
- Monitor for Complications: After mating, watch for signs of infection or distress. A vet can confirm pregnancy about 3-4 weeks after mating.
