Signs Your Dog Is in Heat


Symptoms of your dog being in heat can vary, but they can be similar to human menstrual cycles. Changes in your dog’s behaviour are one sign. Other symptoms include excessive genital licking, bleeding, and a swollen vulva. Learn more about dog in heat and signs that may indicate a problem. Below are some common signs. Once you notice any of these symptoms, seek help immediately.

Changes in behaviour

While your dog may be acting like normal during the onset of heat, it will soon start to behave strangely during this time. It may become restless and more nervous. It may even try to mount you or another dog. Changes in behaviour will also include urinating more often and aggressively towards other dogs. It may also seem hungrier and sexy than normal. During this time, your dog will become obsessed with its body and its behavior.

The first stage of your dog’s heat cycle is known as the proestrus stage. This lasts nine days and is a vital time for a female dog to prepare for mating. The level of estrogen will increase dramatically and ovarian follicles will begin to develop. During this time, your dog will start to display certain behavioral changes, including increased affection for you and clinginess around other male dogs.

One of the most common changes in your dog’s behaviour during the heat cycle is frequent urination. It may also bleed from the vulva, become more aggressive, and become more interested in you. While this behaviour may be alarming, it is not necessarily indicative of a looming pregnancy. Your dog’s urination is one of the first signs of heat, so it’s best to be proactive and catch the changes as they occur.

During the period of estrus, female dogs will need to go outside more often as the swelling of their genitals puts pressure on the bladder. Once this period of hormonal activity has passed, the dog will return to its usual habits. If you notice these signs in your dog, you should make sure your dog is getting enough exercise, and that it is getting plenty of fresh air. It may even exhibit aggressive behavior toward male dogs.

Excessive genital licking

The vulva is the place where puppies develop individuality and begin licking themselves to arouse themselves. This is a normal part of a dog’s life and happens to increase in size during the first phase of the menstrual cycle. This initial bleeding can cause excessive genital licking because the vagina may have become inflamed.

In addition to the genital licking, female dogs may show other signs that they are in heat, including vaginal discharge or bleeding. In addition to the excessive licking, a female dog may also exhibit other behaviors that indicate she is in heat, including mounting and receptive behavior. Additionally, a dog in heat will hold its tail in different positions.

Generally, a female dog reaches sexual maturity between six months and one year of age. This is when they start to exhibit new behaviors such as humping objects and intense licking of their private parts. This is the first sign that your dog is in heat. It is important to take action as early as possible so that you can prevent your dog from resulting in unwanted pregnancy.

If you notice excessive genital licking in your dog, consult a veterinarian. Many female dogs lick their vulva in an attempt to clean them. If this behavior continues, it may be a sign of other problems, such as hormonal imbalances. Ultimately, the licking should stop once the underlying cause is resolved. Even if you can’t see the reason for the behavior, it’s best to get your dog checked by a vet to prevent further problems.


You may notice your dog bleeding when it is in heat, but what is it? A dog is undergoing the proestrus stage, a period that starts seven to 10 days before coming into heat and lasts for nine to 21 days. This is also the time that the vulva reswells and begins to produce a pink discharge. This bleeding usually stops once the vulva returns to normal and the discharge taper off.

Depending on the breed, bleeding when your dog is in heat can last from two to twenty days. While most bleeding occurs during the first two stages of the estrus cycle, dogs with bleeding issues may need to see their veterinarian. The bleeding should not be excessive or have an odor. If bleeding lasts longer than three weeks, your dog is likely suffering from an infection. A veterinarian can help you determine whether bleeding is due to a pregnancy or something else.

Female dogs can be very ovulated when they are in heat. When the estrus phase ends, a female dog is no longer fertile. She will not bleed, or produce a blood-tinged discharge, during this period. In addition, the female may become very interested in male dogs. Therefore, you should keep males away from your female dog while she is in heat. The female dog will also be very aggressive when in heat, and may also bleed unnoticeably.

Another symptom of bleeding during estrus is frequent urination. Bleeding in the vagina can be caused by many reasons, but a dog who is in heat may be infertile. An abnormal pregnancy can lead to an infection and require immediate medical attention. Infected dogs can also be pregnant and may even experience miscarriage. Those signs of a pregnancy should prompt you to visit your veterinarian.

Swollen vulva

When your dog is in heat, it may be showing signs of a vaginal rash on its back side. The vulva is the opening of the dog’s vagina and opens into the urethra. The urethra drains the dog’s urine and connects the vagina to the cervix and uterus. A rash on the vulva can be caused by parasites or a skin infection, and it can be treated by giving your dog cool water and a gentle soap. If the rash persists, however, visit your vet. Other symptoms of a dog’s heat cycle may include a lump or bump on the vulva, which is not considered normal. They can be caused by anatomic abnormalities, infections, or cysts.

Swollen vulva is a symptom of dog insemination, which can lead to an unwanted litter. The vulva will swell to three times its normal size and the female will hold her tail up high and turn her rear toward the male. When the female is in heat, the vulva will also ooze out vaginal fluid and blood. Your dog will also be clingy and may even stand up for a male, hold her tail to her side, and back up his butt to his leg. Vets can tell you if your dog is in heat by examining its vulva.

The first heat cycle in your dog can last three to four weeks. The second heat cycle can last anywhere from four to eight months. Although the timing of these cycles varies, the symptoms usually last for two to three weeks. During the first heat cycle, the vulva will begin to swell and discharge water. When this occurs, your dog will be attracted to males, but they will not allow mating until seven to 10 days after.

Increased receptiveness to company

If your dog is in heat, he or she will be more easily distracted and show signs of increased receptivity to company. Her vulva will be swollen and her vagina will be blood-tinged. The female will be prone to initiating sexual interaction with other dogs. She will also be more affectionate and may become aggressive toward other dogs. Several signs of a female dog in heat will be obvious and easily identifiable.

Your dog is in heat when she is at her pro-estrus stage. This is the stage when her vulva swells and she produces a bloody discharge. Males are attracted to her during this time and begin to show interest. During this stage, she will be receptive to males, but not willing to mate. Her vulva may be slightly large, but she lacks the “mood” to mate. This is her last stage of the heat cycle, which lasts for a hundred to 150 days.

Female dogs go through heat cycles during their entire lives. The length of the period between heat cycles increases with age. The duration between cycles varies, ranging from two to four weeks. The first phase, or proestrus, lasts between three and seventeen days. A female dog’s proestrus stage lasts for nine to 17 days. A female is fertile during the entire period, although she is not receptive to company during the first few days.

During this time, female dogs may also exhibit signs of male attraction, such as presenting their rears to males or flagging their tails. These signs indicate that a female dog is in her season of pregnancy. She will also be grumpy and may begin pestering other dogs in her territory. Make sure to supervise the interactions between males and females. If necessary, set up a baby gate between the two dogs.
