Female Dog in Heat Behavior

Female Dog in Heat Behavior: Discover valuable insights

A female dog in heat can exhibit certain behaviors that can sometimes be alarming or confusing to its owners. In this article, we will discuss the behavior of a female dog in heat, how to recognize when your dog is in heat, and some tips to help you care for your dog during this time.

The heat cycle, also known as the estrus cycle, is the time when female dog is fertile and has the potential to get pregnant. Depending on the breed and individual dog, this cycle normally lasts 2-4 weeks and happens every 6-12 months.

During this time, your dog will experience a range of hormonal changes that affect her behavior, physical appearance, and overall health.

Female dog in heat experience three separate phases during the heat cycle: proestrus, estrus, and diestrus.


The initial phase, proestrus, lasts an average of nine days. During this phase, your dog’s body is preparing for ovulation, and the ovaries are beginning to mature eggs.

During this period, you may see your dog’s vulva swelling and some bloody discharge. Your dog may also be more agitated and irritable than usual.


The second stage of the female dog in heat cycle, known as estrus, typically lasts nine days. Your dog is most fertile and eager to breed at this time of year.

 The bloody discharge may become lighter in color and less apparent at this stage.

Your dog may also become more loving and seek out male dogs for attention. However, it is important to keep your dog on a leash and away from male dogs, as you do not want an unplanned pregnancy.


Diestrus is the last phase of the female dog in heat cycle, lasting an average of 60 days. This is the period when the body is either preparing for pregnancy or preparing to return to its normal state.

If your dog has not been impregnated, she will come out of the heat, and the swollen vulva will gradually return to its normal size. If your dog has been impregnated, the pregnancy will progress through gestation until she gives birth to a litter of puppies.

It is important to note that every dog is different, and the length and intensity of each phase of the heat cycle can vary. While some dogs may show more obvious behavioral changes, others might not show any signs of being impacted at all.

It is also important to keep in mind that during the heat cycle, your dog is at a higher risk of developing certain health problems, such as urinary tract infections or pyometra, a potentially life-threatening infection of the uterus.

As a result, it is critical to constantly watch your dog’s behavior and health during this period and seek veterinarian assistance if you observe any odd symptoms.

What are the signs that my dog is in heat?

A change in behavior is generally the first indication that your dog is in heat. She may become more restless, vocal, or affectionate. You may also notice that she is more interested in male dogs and is actively seeking their attention.

A female dog going through the heat cycle could show a number of signs that she’s in heat.

 These signs can vary from dog to dog, but some common indications that a female dog is in heat include the following:

  1. Swollen Vulva: One of the most obvious signs of a dog in heat is the swelling of the vulva. The vulva will look enlarged, and it may be red or pink than usual.
  2. Change in Behavior: A female dog in heat may act differently than she usually does. She may become more clingy and seek more attention from her owner. She may also become more agitated or restless.
  3. Change in Appetite: During the heat cycle, a female dog’s appetite may increase or decrease. Some dogs may refuse to eat, while others may eat more than usual.
  4. Frequent Urination: A female dog in heat may need to urinate more frequently. This is because the hormonal changes that occur during the heat cycle can cause the bladder to become more sensitive.
  5. Bleeding: Female dogs in heat will typically have some vaginal bleeding, which can range from a few drops to a more significant amount. The bleeding is generally light in color and may have a faint odor.
  6. Tail Wagging: A female dog in heat may wag her tail more often than usual. This is due to her efforts to attract male canines.
  7. During this period, you may see your dog’s vulva swelling and some bloody discharge.

It’s important to remember that not all female dogs in heat will display all of these signs. Some dogs may only show a few of them, while others may show all of them. Additionally, some dogs may not show any signs at all. If you feel your dog is in heat, you should get guidance from your veterinarian on how to handle the issue.

The short answer is no; spayed dogs cannot go into heat. This is because the heat cycle, also known as estrus, is controlled by the female dog’s reproductive hormones, which are produced by the ovaries.

When these organs are removed during spaying, the source of the hormones is gone, and the heat cycle stops.

It’s worth noting that spaying does not happen instantly, and it takes time for the reproductive hormones to leave the body. Depending on the dog’s age, health, and the timing of the procedure, it may take a few weeks to several months for the hormones to dissipate completely.

During this time, the dog may still exhibit some signs of being in heat, such as swollen vulva, increased urination, or behavioral changes. However, these symptoms are temporary and should disappear over time.
