How to prevent pregnancy in a dog if there has already been contact

Indications for termination of pregnancy

The structure of the uterus in domestic animals is such that removing numerous fetuses from the womb of a dog is impossible without severe injury to the organ.
Due to the fact that terminating pregnancy in dogs is associated with a number of difficulties, this surgical procedure is carried out in a veterinary institution only for medical reasons. Veterinarians, as a rule, resort to abortion in dogs in cases where a small female has become pregnant with a very large male. In this case, the risk of complications during childbirth and the birth of non-viable offspring in a dog increases significantly. To save the life of a pet, abortion is a medical indication.

Anomalies in the structure of the animal’s pelvic cavity may also be a reason for artificial termination of pregnancy in a dog. An abnormal structure of the pelvis is detected during an X-ray examination. Childbirth in this case may result in the death of the mother.

Termination of pregnancy by trimester

The arsenal of veterinary medicine includes medications for bloodless abortion, as well as surgical methods. The choice of one method or another depends on the stage of pregnancy.

First

The first trimester phase begins from the moment the eggs are fertilized by sperm and lasts until the embryos are implanted into the uterine wall. This stage of pregnancy cannot be confirmed even with the help of an ultrasound examination of the animal’s abdominal cavity. At this point, a veterinarian can use medications to prevent the animal from becoming pregnant.

Implantation of the embryo into the uterine wall

High doses of estrogen can interfere with the fertilization of eggs and their consolidation in the uterine cavity. Their introduction is necessary as soon as possible after the intended mating. As a rule, hormonal agents are effective when used 3–5 days after mating of a female with a male.

Estrogen-based drugs have a detrimental effect on the egg; they increase the period of stay of embryos in the oviducts, preventing their implantation into the uterus. Hormonal drugs cause changes in the structure of the uterine mucosa, as a result of which the endometrium loses its ability to attach embryos.

The use of high doses of estrogens has a number of contraindications and is associated with the risk of severe complications. Veterinary specialists usually warn owners about the consequences of using medical abortion. In particular, the use of estrogens often leads to the destruction of the animal's bone marrow, severe inflammation in the uterus, bleeding and death.

In veterinary practice, Mesalin, which is a solution of estradiol, is most often used. The drug should not be used for diabetes mellitus in dogs, as well as for any diseases of the genital area (pyometra, endometritis, pathology of the mammary glands). Oncological diseases are also on the list of restrictions on the use of the drug for artificial abortion in dogs.

Second

The second trimester begins from 20 to 22 days after mating of the animal. During this phase, instrumental diagnosis of pregnancy using ultrasound is possible. It is possible to perform an artificial termination of pregnancy in the second phase by resorption of the fetuses or their expulsion from the uterus. This kind of effect on the body of a pregnant female is exerted by prostaglandins or dopamine agonists.

In the first trimester, prostaglandins do not have the desired effect on the body of a pregnant dog, which is due to the resistance of the corpus luteum to the luteolytic action of the hormone. In this regard, this drug is used only from the 30th day of pregnancy of the pet. Prostaglandins cause vasoconstriction of the corpus luteum, which leads to its death.

In addition, the hormone reduces the production of progesterone in the body of a pregnant individual and causes contraction of the uterine muscles. This mechanism of action leads to the expulsion of the fruits.

The administration of the drug is carried out strictly under the supervision of a veterinary specialist, who uses ultrasound or x-ray examination to confirm the fact of expulsion of embryos from the uterus. Prostaglandins for artificial abortion are used in dogs no older than 7 years. During the period of drug administration, the animal experiences tachycardia, drooling, vomiting, and signs of respiratory failure.

In the practice of a veterinarian, prostaglandins are often replaced by synthetic analogues - Fluprostenol, Cloprostenol, Alpha-prostol. The drugs promote the resorption of fruits and act more gently in contrast to natural prostaglandins.

Third

In the third trimester, fetal calcification occurs in the womb and resorption medications are no longer used. It is possible to artificially terminate a pregnancy using medication during this period only by expelling the fetus. Dopamine agonists are used in veterinary practice to suppress prolactin secretion. The administration of Bromocreptine and Cabergoline leads to termination of pregnancy.

Surgical termination

In some cases, a veterinarian recommends owners to terminate a dog’s unwanted pregnancy surgically. In this case, we are not talking about abortion in the generally accepted concept.

With this manipulation in dogs, due to the specific structure of the uterus, not only the fetuses are removed, but also the reproductive organ itself. This operation is called sterilization of a pregnant female. After surgery, the animal loses its ability to reproduce.

Surgical termination of pregnancy is classified as a complex operation. During conventional sterilization, the removal of the uterus and ovaries usually occurs during the so-called interphase. In rare cases, they resort to surgery during the period of estrus. The blood supply to the reproductive organs during these physiological periods of the female is minimal, and the risk of postoperative complications is low.

In the case of sterilization of a pregnant female, the surgeon deals with a high degree of blood supply to the uterus. As the fruits develop, they lead to an enlargement of the organ. In this regard, the owner must understand that the risk of postoperative complications is high, and resort to this type of operation in exceptional cases.

Consequences

Most abortion methods cannot be considered safe. All of them negatively affect the animal’s body, to one degree or another.

The most common consequences:

• Sterility. Most often, this is the result of a late abortion, since the structure of the genital organs of dogs does not imply the possibility of removing fully formed puppies from the uterus directly without causing critical harm to the genitals.
• Hormonal imbalance, which can result in diseases of the genitourinary system. This is the result of the use of strong drugs that completely change the hormonal levels at a certain period and provoke the fading of the development process of the embryos.

Most veterinarians strongly advise resorting to means of termination only as a last resort and in the early stages. They try to do late-term abortions only for medical reasons, as this causes irreparable harm to health, both physical and mental.

Also a prerequisite for maintaining the health of the animal is an examination some time after the procedure. Depending on the method and period at which the procedure was performed, the animal is shown to the veterinarian several times, while performing an ultrasound examination of the uterus and ovaries to make sure that there will definitely be no offspring, and to outline the range of complications after the operation.

Recovery of a dog after

After medical termination of an unwanted pregnancy, the dog needs a recovery period. The owner must closely monitor the health of the pet, since the use of hormonal injections for resorption or expulsion of the fetus often leads to serious problems.

During the recovery period, on the recommendation of a veterinarian, the animal is prescribed multivitamin preparations containing vitamins A and E, and ascorbic acid. The female's diet is enriched with taurine and complete protein.

Veterinary experts recommend that owners allow the next breeding of a dog no earlier than a year after the artificial termination of pregnancy with hormonal drugs.

If a decision has been made to sterilize a pregnant female, then postoperative care for the animal is no different from that during a planned operation.

We recommend reading about fever in dogs. You will learn about the causes and types of hyperthermia, symptoms, rules for measuring the temperature of an animal, and treatment of fever. Learn more about the symptoms and treatment of enterovirus in dogs.

Abortion in dogs is carried out only for serious medical reasons. Artificial termination of pregnancy is carried out using hormonal injections. The use of hormones for resorption and expulsion of fetuses has a number of contraindications and is often accompanied by complications. Surgical termination of pregnancy in dogs is impossible without removing the uterus along with the fetuses developed in it (sterilization).

When contacting the clinic after mating

If the owner brought his pet to the clinic from the first to the fourth day of pregnancy, then the doctor can treat with drugs that contain the hormone oxytocin.
Such pills or injections for abortion in dogs are the most reliable way to contract the uterus and cause spontaneous miscarriage. If you are not sure that pregnancy has occurred, then it is best to use traditional methods or medications in order to prevent embryo implantation as much as possible. Such prevention poses virtually no threat to your pet’s health; it can be done at home yourself.

If, nevertheless, an unwanted pregnancy is already developing in your dog, then it is worth performing an ultrasound examination and only a doctor should decide on the advisability of an instrumental abortion.

Alizin for safe termination of pregnancy in dogs

Delicate situation You want to control your dog's reproductive cycle and avoid unwanted pregnancy, but you are afraid that: • The dog has mated while in heat • Spent some time outside without supervision and there is a risk that she is pregnant • Pregnancy and childbirth are dangerous for her, so as a bitch is too old or, conversely, too young, or has become pregnant with a male of the wrong size. Your veterinarian may suggest terminating your dog's pregnancy, guaranteeing complete safety, and the use of anti-hormones is the best solution to this problem.

When should Alizin be used?

From the first day of mating until the 45th day of pregnancy. Since the drug contains anti-hormones, it is ideal for use in the early stages, before the 22nd day of pregnancy, which allows you to terminate it without negative consequences for the dog. Your veterinarian can start using anti-hormones at a later date (from 22 to 45 days), ensuring complete safety and effectiveness of the drug. During administration of the drug, there may be a local transient reaction. We guarantee that when using Alizin, you do not have to worry about the health of your dog.

Is fetal expulsion a “visible” process?

Termination of pregnancy is a fairly quick process, taking on average 4 days (extreme values ​​- from 1 to 7 days). By licking the genital area, the dog absorbs all the discharge and you do not see it. If they are still noticeable, they will quickly become colorless and liquid.

How to confirm the effectiveness of Alizin?

10 days after the first injection, an ultrasound can be performed to confirm the effectiveness of the drug.

If she acts like she's pregnant...

Late termination of pregnancy results in expulsion of the fetus. Your dog's behavior at the moment may be similar to pregnancy behavior, which is completely normal: • The dog may be lethargic, have a loss of appetite, or vice versa • It may be agitated, panting, or exhibit other signs characteristic of pregnancy These symptoms are temporary and do not pose a threat to the dog. Your veterinarian is your assistant. Your veterinarian will help you monitor and plan your dog's reproductive cycle. Termination of pregnancy using anti-hormones is a medical intervention that should only be performed under the supervision of a veterinarian. This will help avoid unwanted consequences of an unplanned pregnancy.

Can a bitch get pregnant again?

Anti-hormones have the advantage that whether they are used early or late in pregnancy, they do not affect the reproductive cycle. They do not increase the risk of uterine infections and do not affect the overall level of productivity. A female dog may begin to come into heat 1 or 3 months earlier, but subsequently the usual cycle will return to normal. Since anti-hormones do not affect the estrus cycle, the use of “Alizin” during it does not have a preventive contraceptive effect. If mating occurs, the dog may become pregnant, so keep an eye on her until the end of her heat and do not let her breed Vetprom LLC 117218, Moscow, st. B. Cheryomushkinskaya, 28, building 7A

Termination of pregnancy in dogs in the early stages is a rather complex and very responsible process that must be performed exclusively by a highly qualified veterinarian in a medical facility.

It is the issue of unwanted mating in dogs that is more pressing than in cats. This is due to the fact that it is the process of fertilization of a cat that is often not noticed by the owner, which cannot be said about a dog.

Consequently, dog owners often turn to veterinary clinics regarding the issue of eliminating the unwanted pregnancy of their pet.

As for the question - is it possible to terminate a dog's pregnancy, the answer here is unequivocal - of course it is possible. To achieve this, in veterinary practice there are three types of problem solving:

• the pet is given a special hormonal medicine that affects the state of hormones produced by the pet’s endocrine system and the fertilized egg simply cannot attach to the wall of the uterus;
• medical miscarriage;
• abortion using instrumental intervention.

It should also be noted here that not all drugs are suitable for eliminating the problem at an early stage, so the drug should be selected exclusively by a doctor, based on the results of tests and examinations of the animal.

Thus, artificial termination of pregnancy in dogs is used quite widely in order to avoid unwanted offspring. The relevance of this procedure has been at a high level for a long time and will probably never lose its relevance.

Alizin

Pharmacological properties Pharmacological group: hormones and their antagonists. Aglepristone, which is part of Alizin®, is a synthetic steroid that is a progesterone antagonist.

Aglepristone blocks progesterone receptors in the uterus, disrupting the normal physiological process of maintaining pregnancy in bitches, which leads to abortion or fetal resorption. The ability of aglepristone to bind to uterine progesterone receptors in dogs is 3 times higher than that of progesterone.

Aglepristone does not change the concentrations of progesterone, prostaglandins, oxytocin or cortisol in the blood plasma within 24 hours after its administration, but promotes the release of prolactin within 12 hours after injection.

The maximum concentration of aglepristone is observed in the blood 2.5 days after administration of the drug. Aglepristone is biotransformed in the liver and excreted from the body mainly in feces.

Indications for use : Used to terminate unwanted pregnancy in domestic animals up to 45 days after accidental mating. Alizine is also used to treat pyometra in dogs and cats without surgery.

Doses and method of administration Alizin is used after the end of the estrus period. The drug is administered to dogs under strictly aseptic conditions, subcutaneously in the withers area, twice, with an interval of 24 hours at a dose of 10 mg/kg of animal weight (0.33 ml of solution per 1 kg of animal weight).

For cats, the drug is administered at a dose of 10 mg/kg body weight once every 24 hours. Doses of Alizin, in volumes over 5 ml, should be administered at different points. Duration of drug administration: for dogs - 0-45 days of pregnancy, cats - 7-8 days after mating.

The effectiveness of the drug is 99% (when used before the 25th day) and 96% (when used before the 45th day).

The dose of the drug depending on the weight of the animal is:

After administering the drug, it is necessary to lightly massage the injection site. If the volume of the injected solution exceeds 5 ml, then the drug must be administered at several points. Abortion (or fetal resorption) occurs within 7 days after the administration of Alizin.

After use, a follow-up visit is required for examination and confirmation of termination of pregnancy by ultrasound.

If pregnancy is terminated in the early stages - 20 days after treatment, in the middle stage - after 8 days.

In case of incomplete abortion, treatment (2 injections of Alizin at a dose of 0.33 ml/kg/day with an interval of 24 hours) can be repeated after 10 days, between 30 and 45 days of pregnancy.

After using the drug, subsequent estrus occurs in accordance with the physiological norm, ensuring unhindered pregnancy and childbirth.

Side effects In case of increased individual sensitivity in animals, allergic reactions are possible. When Alizin is administered, local inflammation and pain at the injection site may occur. In bitches treated after the twentieth day of pregnancy, abortion may be accompanied by signs of physiological labor, that is, expulsion of the fetus, slight loss of appetite and stagnation of milk.

Contraindications Individual hypersensitivity of the animal to aglepristone. The drug should not be used in dogs with impaired liver, kidney or adrenal function, as well as in patients with diabetes.

Special instructions When working with the medicinal product Alizin, you should follow the general rules of personal hygiene and safety precautions provided for when working with medicinal products for animals.

Storage conditions Alizin® is stored in the manufacturer's sealed packaging, in a dry place, protected from light, out of reach of children and animals, separately from food and feed at a temperature of 15 °C to 25 °C. The shelf life of the medicinal product, subject to storage conditions, is 3 years from the date of production.

Abortion technique for dogs

Preventing unwanted pregnancy in dogs is a process that is done a little differently than in humans. This difference lies in the fact that a woman after an abortion can have children, but it is unlikely that she will have a pet.

In the event that an animal has managed to become pregnant undesirably, it will not be possible to simply pull the puppy out of the uterus, since its structure is significantly different from the aging of the female organ.

Instrumental abortion carries certain risks for the pet and it is possible that the stage can be so difficult that the bitch will never be able to get pregnant again.

Due to very difficult access to the reproductive organs, it is very difficult to clean out the uterine cavity, and blood loss can be so severe that it will simply be impossible to stop it and the dog may simply die during the operation. In most cases of abortion, there is no way for dogs to pull the puppy out without damaging the reproductive organ itself, which becomes significantly larger during pregnancy.

Many veterinarians take this step only if the bitch is a breeding dog and an abortion is simply necessary, since the mating was carried out with a simple dog that has no pedigree. The puppy is removed very carefully so as not to cause colossal harm to the uterus and nearby organs. After the operation, it is necessary to monitor the stitches so that no complications arise.

Gentle ways to terminate pregnancy in dogs

In this section, it becomes necessary to consider medicinal methods of cleansing the dog’s uterus. It is worth noting right away that there is no universal cure for pregnancy, but its occurrence can be prevented.

The desired result is achieved in most cases if the remedy is administered as early as possible. After such an injection, fertilization simply becomes impossible, which is what was required. But, it should be noted that this approach also carries false risks and can significantly affect the health of the animal, with various complications.

How to quickly terminate a dog's pregnancy is achieved through an approach such as sterilization of bitches. However, after this the female will never be able to become pregnant and bear puppies. This is due to the fact that during the operation not only the puppy and the uterine space are removed.

If an unwanted pregnancy occurs in dogs, what should you do? You must immediately contact a veterinarian, who will help solve the problem quite effectively.

Main signs of abortion

What symptoms indicate what happened? The most common sign of an abortion is sudden bleeding from the external genitalia. In some cases, a piece of placenta may hang from the genital slit. In some cases, the aborted fetuses themselves may be found. If you notice any of these signs in your pregnant dog, take him to the vet immediately. We warn you once again that grabbing puppies, blood and other secretions released during an abortion with your hands is very dangerous. In particular, if your pet is sick with brucellosis, then you will most likely remain disabled for life. Don't take risks!

Interrupt methods

When the pregnancy is confirmed and the decision is made, the doctor can offer two options: surgery and medical termination. As for the operation, this method is absolutely inhumane and can lead to the death of the dog on the operating table. In addition, it is necessary to understand that such an interruption entails a complete inability to have puppies in the future, which is due to the structural features of the animal’s body. But if this does not stop you and you need to sterilize your dog, then it is better to do it during the period when she is not pregnant, it is much safer.

Terminating a dog's pregnancy using tablets is gentler on the animal. There are several types of drugs for abortion in dogs:

• medications of a number of estrogens. Their peculiarity is that they should be used immediately after sexual intercourse. Such drugs have many side effects: from infertility to serious problems with the functioning of certain organs.
• prostaglandins. This is the safest method of terminating a pregnancy, although it may have unpleasant consequences. However, the risk of such consequences is less than in the first case. The drug is administered after it has been determined that the dog is pregnant using ultrasound. Used to terminate early pregnancy in dogs.
• and finally glucocorticoids. These are drugs for dogs in their final stages. Such actions can lead to the most dire consequences, including the death of the animal. Therefore, think carefully about your decision before making it.

Methods

There are several ways to terminate an unwanted pregnancy, which have proven their effectiveness in practice. They are used depending on the period and individual characteristics of the dog.

Only a professional doctor after a thorough study can choose the right way to get rid of the problem. Do not perform such a complex procedure at home with previously untested drugs.

Even if the dog has already gone through the procedure twice without problems, on the third time something irreparable can happen. The canine reproductive system is complex and often unpredictable.

Now one of the most popular drugs is Alizin, the main active ingredient of which is aglepristone. The main advantage of the composition is that it can be used both in early and late stages, changing doses.

If pregnancy is confirmed, then it is enough to call a veterinarian at home and give the necessary injections. The number of injections and the volume of injected substance is calculated individually, based on the stage of pregnancy and the size of the animal. After 10-15 days, depending on the size of the fetus, a medical miscarriage will occur.

Preventing Pregnancy in Dogs

In order not to endanger the life of your four-legged friend, you should know that there are also ways to prevent pregnancy in a dog. These methods are quite banal and do not entail any health problems for the animal. It is necessary to try in every possible way to protect your pet from sexual intercourse during the period of estrus. For this:

• when walking, you should avoid large crowds of dogs, as there is a high probability that the situation may get out of your control;
• do not let your pet off the leash;
• Use sanitary panties for walks. You can buy them at any pet store. They will help protect the dog from sexual intercourse and will also cheer up the owner with their cute appearance.

There are also drugs that can suppress the sexual instincts of our four-legged friends: contrasex, sex barrier and others. Such drugs are used during the period of estrus and allow you to solve the problem before the dog begins an unwanted pregnancy.

According to the famous classic, we are responsible for those we have tamed. Don't forget about this. Animals acutely feel stress and pain from medical interventions. Of course, situations can be different, and termination of pregnancy is sometimes the only way to save the life of a pet (the impossibility of a successful birth, for example, may be due to the structural features of the animal’s pelvic bones). However, you should always remember that you create less of a threat to your dog's health by preventing her from becoming pregnant. Interruption should be resorted to in extreme cases.

Termination of pregnancy in dogs

The earlier the better

In most cases, drugs for abortion in dogs are selected based on the duration of pregnancy and the individual characteristics of the pet’s body. However, it is worth understanding that the sooner you contact the clinic with the problem of an unwanted pregnancy in your pet, the greater the chance that everything will go through without consequences for him.

Some breeders try to prevent pregnancy even before the onset of estrus, so the pet is given special injections or prescribed birth control pills. The cost of such therapy is set exclusively by the medical institution where the procedure will be performed.
