Ways To Know If Dog Mating Is Successful: Easy Guide

Dog mating is a natural and essential aspect of canine behavior, and for dog owners, it is important to understand how to determine if the mating process has been successful. Successful mating results in a successful pregnancy, which can bring a new litter of puppies into the world. However, determining if the mating has been successful is not always as straightforward as it may seem. In this article, we will discuss various ways to know if dog mating has been successful, from physical and behavioral indicators in both male and female dogs to the role of a veterinarian in confirming successful mating. By understanding these signs, dog owners can ensure the health and well-being of their pets and their potential future puppies. 

Ways To Know If Dog Mating Is Successful: Easy GuideWays To Know If Dog Mating Is Successful

Physical signs: 

One of the most obvious ways to know if dog mating is successful is by observing the physical signs in both the male and female dog. The male dog’s penis will become erect and swollen, and the female’s vulva will also become swollen and receptive.


During mating, the male dog’s penis will swell and lock inside the female’s vagina. This usually lasts for 20-30 minutes or even longer. This locking mechanism ensures that the male’s sperm is safely delivered to the female’s reproductive system.

Behavior Change: 

After successful mating, both the male and female dog will exhibit a change in behavior towards each other. The male dog will be less interested in mating while the female will become more relaxed and may even show signs of nesting behavior.

Proestrus and Estrus cycle: 

Female dogs have a unique reproductive cycle known as the estrus cycle, which is divided into four stages – proestrus, estrus, diestrus, and anestrus. If the female successfully ovulates and gets pregnant, she will not enter heat again until after the birth of her puppies.

Post-mating disinterest: 

After successful mating, male dogs often lose interest in mating and may even show disinterest in other female dogs. This is because their natural instinct is to protect and bond with the female they successfully mated with.

Vaginal discharge: 

A clear watery discharge from the female’s vagina is a normal sign after successful mating. It is a sign that the male’s sperm has successfully reached and fertilized the female’s eggs.

Pregnancy symptoms: 

If the mating was indeed successful, the female dog would start showing signs of pregnancy after a few weeks. These symptoms may include nausea, increased food intake, and nesting behavior.

Ultrasound or X-ray: 

If you want to know for sure if the mating was successful, you can take your female dog to a veterinarian for an ultrasound or X-ray. This can help confirm pregnancy and also give you an estimate of how many puppies to expect.

Consult a professional: 

If you are unsure about the success of the mating, it is always best to consult a professional veterinarian. They can perform a physical examination and may also take a blood test to check for pregnancy hormones.

How Many Times Should a Dog Mate To Get Pregnant?

It is generally recommended for a dog to mate multiple times in order to increase the chances of pregnancy. Some experts suggest mating every other day for 5-7 days during the female’s heat cycle. This allows for the male’s sperm to replenish and increases the likelihood of fertilization. It is important to consult with a veterinarian for specific advice on breeding and pregnancy planning for your dog.

Dog Mating Process

The dog mating process can be divided into four stages: proestrus, estrus, metestrus, and anestrus.

  1. Proestrus: This is the first stage of the mating process and usually lasts for 9-10 days. During this stage, female dogs will experience a swollen vulva and a bloody discharge. However, they are not yet receptive to mating at this time.
  2. Estrus: Estrus is the second stage and is also known as the “heat” cycle. It usually lasts for 4-7 days but can vary among different dog breeds. During this time, the female is receptive to mating and will seek out male dogs. She may also exhibit behavior such as restlessness, increased urination, and a decrease in appetite.
  3. Metestrus: This is the third stage, which follows estrus and lasts for 60-90 days. If the female dog has mated successfully, she will become pregnant during this stage. However, if she does not mate, she will go through a false pregnancy, where she may show signs of pregnancy such as nesting or producing milk.
  4. Anestrus: The final stage is anestrus, which is a resting period for the female dog’s reproductive system. This phase can last for about 4-5 months, and during this time, the female’s hormone levels return to normal. If the female does not mate, she will go back to the proestrus stage, and the cycle will repeat.

During the mating process, the male dog will usually mount the female from behind and hold on to her with his forelegs during ejaculation. The male’s penis will swell during mating and will remain locked inside the female for about 15-20 minutes. This is a natural process, and it may not require assistance from humans.

If the mating is successful, the female will go through a gestation period of about 63 days before giving birth to a litter of puppies. It is important to ensure that both the male and female dogs are healthy and have up-to-date vaccinations before mating. It is also recommended to consult with a veterinarian for proper care and guidance during the mating process.

Dog Mating Age

Dogs can reach sexual maturity anytime between 6 months to 2 years of age, depending on the breed. However, it is important to note that just because a dog is physically able to mate, it does not mean they are mentally or emotionally ready for it. It is recommended to wait until the dog is at least 1-2 years old before breeding to ensure they are mature enough to handle the responsibility of pregnancy and raising puppies. Additionally, it is important to thoroughly research and prepare for the breeding process before considering mating a dog.

What to Expect From a Female Dog After Mating

After mating, there are a few changes that you may notice in your female dog. These changes can vary depending on factors such as the dog’s age, breed, and individual temperament. Some common things to expect from a female dog after mating include:

  • Behavior Changes: After mating, female dogs may experience changes in their behavior. They may become more affectionate and clingy towards their owners, as well as other dogs in the household. This is because they are going through hormonal changes and may be feeling more vulnerable. On the other hand, some female dogs may become more aggressive or irritable due to increased levels of testosterone.
  • Swollen Vulva: One of the most noticeable changes after mating is a swollen vulva. This is due to the increased blood flow to the reproductive organs during and after mating. The vulva may remain swollen for a few weeks as the dog’s body prepares for pregnancy and birth.
  • Increased Urination: Female dogs may urinate more frequently after mating. This is because the act of mating can stimulate the bladder, causing it to urinate more often. Additionally, the increase in progesterone levels during pregnancy can also lead to increased urination.
  • Nesting Behavior: Some female dogs may exhibit nesting behavior after mating. This is an instinct for pregnant dogs to prepare for the birth of their puppies. They may gather blankets, towels, or other soft materials to create a comfortable and safe spot to give birth.
  • Loss of Appetite: Some female dogs may experience a loss of appetite after mating. This can be due to hormonal changes or the stress of pregnancy. It is important to monitor their food intake and make sure they are still eating enough to maintain their health.
  • Pregnancy: If the mating was successful, you can expect your female dog to become pregnant. However, this may not be obvious immediately, and it may take a few weeks to confirm pregnancy through a veterinarian exam or ultrasound. It is important to provide your pregnant dog with proper nutrition and care to ensure a healthy pregnancy and delivery.
  • False Pregnancy: Sometimes, even if the mating was unsuccessful, a female dog may exhibit symptoms of pregnancy. This is known as a false pregnancy, and it is caused by hormonal changes. Symptoms may include behavioral changes, nesting behavior, and swelling of the mammary glands. This typically resolves on its own within a few weeks.

What to Expect From a Male Dog After Mating

After mating, male dogs may exhibit some behavioral and physiological changes. Here are a few things you can expect from your male dog after mating:

  • Increased territorial behavior: After mating, male dogs may exhibit increased territorial behaviors, which is a normal instinctual response to protect their mate and potential offspring. They may become more aggressive towards other animals, especially male dogs, and may mark their territory more frequently to assert dominance.
  • Decreased interest in mating: Once a male dog has successfully mated, his hormones will decrease, causing a decrease in interest in mating. This is a natural response and is not a cause for concern.
  • Increased affection towards the female: Male dogs may become more affectionate towards the female dog they have mated with. This is because they have formed a bond with her and may want to protect and provide for her during her pregnancy.
  • Swollen and pink-colored genitals: The male dog’s genitals may appear swollen and pink-colored after mating. This is due to increased blood flow to the area and is a normal part of the mating process. The swelling should subside within a few days.
  • Increased urination: Male dogs may urinate more frequently after mating. This could be due to increased marking behavior or a response to the changes in their hormones.
  • Increased appetite: Some male dogs may have an increased appetite after mating. This is because they are burning more energy during the mating process and may need to replenish their energy levels.
  • Possible irritation or discomfort: Male dogs may experience irritation or discomfort in their genital area after mating. This could be due to the physical activities involved in mating or if the female was in heat and her hormones triggered a stronger response in the male. If the irritation persists, it is best to consult a veterinarian.

Why Do Female Dogs Cry After Mating?

Female dogs sometimes cry after mating as a result of the hormone oxytocin, which is released during mating. Oxytocin is often referred to as the “love hormone” because it is associated with bonding and connection. When oxytocin is released, it can cause the female dog to become more attached to the male dog and to feel more emotional. In addition, mating can be physically and emotionally stressful for female dogs, which can also lead to crying. Finally, the act of mating can also cause the female dog to experience discomfort or pain, which can also lead to crying. 

What Happens If You Pull Dogs Apart When Mating?

Pulling dogs apart during mating can cause both physical and emotional harm to the dogs involved. It is not recommended to intervene in mating as it can be dangerous for both dogs and may cause them to become aggressive or fearful.

Physically, pulling dogs apart during mating can cause injury to their reproductive organs or other parts of their body. This can result in pain, and bleeding, and may even require medical attention.

Emotionally, dogs may become distressed, confused, or anxious when pulled apart during mating. This can negatively impact their relationship and may even lead to behavior problems.

Additionally, interfering with the natural mating process can disrupt the hormonal and behavioral cues that are necessary for successful breeding. This may decrease the chances of the dogs producing healthy offspring.

It is important to allow dogs to mate and complete the mating process naturally without interference. If there are concerns about the health or safety of the dogs during mating, it is best to seek guidance from a veterinarian or animal behaviorist. 

Tips For Preventing Mating Problems In DogsMAT 2

  1. Spay or neuter your dog: The most effective way to prevent mating problems in dogs is to spay or neuter your dog. This eliminates the urge for your dog to mate and can also prevent unwanted litter of puppies.
  2. Keep your dog leashed when outside: If your dog is intact, it’s important to keep them leashed when outside to prevent them from wandering off and mating with other dogs. This is especially important when your dog is in heat.
  3. Monitor their interactions with other dogs: Make sure to keep a close eye on your dog when they are interacting with other dogs, especially if they are of the opposite sex. If you notice any signs of mating behavior, separate them immediately.
  4. Train your dog to respond to commands: Training your dog to respond to commands such as “come” and “leave it” can help prevent them from running off to mate with another dog.
  5. Socialize your dog with other animals: Socializing your dog with other animals from a young age can help prevent aggressive or dominant behavior, which can lead to mating problems.
  6. Consider using a deterrent: If your dog is being overly aggressive or persistent in trying to mate, you may want to consider using a deterrent such as a citronella spray or a loud noise to distract them.
  7. Use a crate or playpen: If you are unable to supervise your dog, consider using a crate or playpen to restrict their access to other dogs.
  8. Keep your dog away from dogs in heat: If your dog is intact, it’s important to keep them away from other dogs in heat. The scent of a female in heat can be very tempting for male dogs and could lead to mating.
  9. Keep your female dog indoors during heat cycles: Female dogs can become very attractive to male dogs when they are in heat. To prevent unwanted pregnancy, it’s best to keep your female dog indoors during her heat cycle.
  10. Consult a trainer or behaviorist: If your dog is displaying problematic mating behaviors, it may be beneficial to consult a professional trainer or behaviorist for guidance on how to correct these behaviors.

A. After mating, dogs may exhibit a variety of behaviors. Some dogs may become protective of the female, while others may become more submissive. The male dog may become more aggressive, while the female may become more calm and reserved. Both dogs may become more clingy and attached to their owners. In some cases, dogs may become restless and anxious.

Q. How do you ensure a successful dog mating?

A. There are several things you can do to ensure a successful dog mating. First, you should make sure both dogs are healthy and in good physical condition. Second, you should introduce the dogs to each other gradually and allow them to get to know each other before attempting to mate. Third, you should monitor the mating process and ensure that both dogs are comfortable and not showing signs of distress. Fourth, you should be prepared for the possibility of complications during or after the mating process, and have a veterinarian on call if necessary.

Q. How long do dogs need to stick together when mating?

A. The amount of time that dogs need to remain “stuck” together during mating, also known as the copulatory tie, varies depending on the breed of dog and the individual dogs involved. In general, however, most experts recommend allowing dogs to remain tied for at least 10-15 minutes after the male dog has ejaculated. During this time, the female dog’s vaginal muscles will contract around the male dog’s penis, which helps to ensure that the sperm is deposited as close to the eggs as possible. After the copulatory tie, the dogs will typically separate naturally.

Q. How long does it take for a male dog to release sperm?

A. The time it takes for a male dog to release sperm, also known as ejaculation, varies depending on the individual dog. However, on average, it takes about 10-20 seconds for a male dog to ejaculate after penetration.


In conclusion, there are several ways to determine if a dog mating is successful. These methods can include observing the physical behavior of both dogs, taking note of the timing and frequency of the mating, and conducting a veterinary examination. Additionally, pregnancy tests and ultrasounds can also confirm a successful mating. It is important to consult with a veterinarian and carefully consider all factors before determining if a dog mating was successful.
