Is Alizin Safe For Dogs

Alizin is a medication that safely and successfully induces abortion in dogs when there has been a miscarriage. It contains a synthetic progesterone antagonist that suppresses the signals necessary for successful ovarian implantation and subsequent pregnancy maintenance.

What negative consequences does Alizin have in canines?

There may be oedema, skin thickening, enlargement of the local lymph nodes, and ulceration. Every local reaction is reversible and typically goes away 28 days following the injection. 4.5% of dogs received the veterinary medicinal medication during field testing, which caused haematological/biochemical alterations.

When should you give Alizin to your dog?

Consequently, before 35 days of gestation is the ideal time for the diagnosis and treatment of a misalliance with Alizin (though Alizin is registered for use up to Day 45 after mating). There won’t be a foetal expulsion as a result of this, and most often merely a mild mucoid vaginal discharge is observed.

Do dogs have access to abortion pills?

There are several reasons why pet owners might prefer to stop their animals from getting pregnant.

There are several reasons why pet owners might prefer to stop their animals from getting pregnant. If your dog becomes pregnant, it is a typical concern, but there are safe pregnancy termination methods you can use. It is advised that you first seek the counsel and aid of a medical practitioner if you are thinking about halting a dog’s pregnancy in order to fully assess the risks and potential adverse effects.

However, it’s also crucial to remember that dogs can miscarry or have spontaneous abortions for a variety of medical conditions. Here, both scenarios will be discussed.

Symptoms and Types

The most typical sign of a spontaneous abortion in a dog is irregular vaginal bleeding; in rarer situations, an ejected fetus may be discovered. Fetal death brought on by an imbalance in hormones is the most frequent reason for a spontaneous abortion.

The most frequent post-procedure symptom in cases of scheduled abortions is bleeding. It is important that you watch your dog carefully so that any adverse effects or health-related problems can be addressed right away.


An ultrasound machine can identify a dog’s pregnancy. Additionally, many medical professionals typically require an ultrasound of the fetus before they will consent to a medical abortion. If the pregnancy is advanced enough, doppler-style devices can also be used to hear the heartbeat of the fetus.


There are various medical solutions to take into account for owners looking for secure methods to either prevent an undesirable pregnancy or terminate a potential pregnancy. Dogs should be spayed (ovariohysterectomy) to permanently prevent conception. The most popular medical methods for ending pregnancies are as follows:

Injectable estrogens: These can be given by a doctor to prevent pregnancy. To be effective, the estrogen must be administered soon after copulation. However, there are a number of possible adverse effects to consider, including pyometra and bone marrow suppression (i.e., infection of the uterus).

Oral estrogens are not advised due to their inefficiency and potential for causing pyometra in animals.

When administered to pets under the supervision of a medical practitioner, the natural hormone prostaglandin F2 alpha has been found to induce a safe abortion. If any side effects do occur, they are often minor. The medication’s reported side effects include include nausea, diarrhea, shaking, and panting.

Dexamethasone is another effective alternative for causing an abortion in pets. Following the injection, common adverse effects include panting, excessive drinking (polydispia), and frequent urinating (polyuria).

Living and Management

It’s crucial to remember that, contrary to popular belief, postcoital douches do not successfully end an unintended pregnancy in animals. Both planned and spontaneous abortions may result in significant discomfort, vaginal bleeding, or unusual discharge. Owners of pets should pay close attention to their animals’ behavior to prevent the emergence of more severe issues.

What can I feed my dog to induce pregnancy?

Unwanted and unauthorized cat-dog breeding is a widespread worry. Ovariohysterectomy can end a pregnancy or fully prevent it. It is advisable to confirm an unwanted pregnancy before moving through with termination, unless neutering is agreed upon, as 60% of misbred female dogs do not conceive. Post-couple douches had no effect on avoiding unintended pregnancy. Although injectable estrogens, when used properly, can prevent pregnancy, their usage is not recommended due to the high risk of major side effects, such as pyometra and potentially deadly bone marrow suppression. Given during diestrus, oral estrogens considerably increase the chance of pyometra, are ineffective at ending pregnancies, and are therefore not recommended.

By administering prostaglandin F2alpha (a natural hormone) at 0.1 mg/kg, SC, three times a day for 48 hours, and then 0.2 mg/kg, SC, three times a day to take effect, both dogs and cats can safely and effectively end their pregnancies (until all fetuses are evacuated as confirmed by ultrasonography). Treatment periods might last up to 14 days. The duration of treatment in dogs can be shortened (often by 48 hours) by giving prostaglandin E (misoprostol) intravaginally at a dose of 13 mcg/kg/day. At this dosage, prostaglandins’ negative effects (panting, trembling, nausea, and diarrhea) are modest and momentary. Prostaglandins have a limited therapeutic window, thus doses must be carefully calculated. Currently, synthetic prostaglandins (cloprostenol 13 mcg/kg every 1224 hours to effect) are recommended because they more precisely target the myometrium and have fewer systemic side effects.

Dexamethasone, at a dose of 0.2 mg/kg, PO, bid to effect, can also effectively end pregnancy in female dogs. The detrimental effects of administering corticosteroids should be made known to the owner (eg, panting, polyuria, polydipsia).

It has been reported that combination drug protocols (cabergoline 5 mcg/kg, PO, divided every 24 hours for as long as 10 days, and cloprostenol 1 mcg/kg given SC twice at 28 and 32 days after the LH surge) reliably terminate pregnancies with the fewest side effects, shortest treatment times, and highest success rates; their cost and requirement for compounding are drawbacks.

Abortifacients like aglepristone are safe and effective, but access to them is still a problem.

What dose of Alizin should I give my dog?

Aglepristone 10 mg per kg of bodyweight, or 0.33 ml of veterinary medicine per kg of bodyweight, should be given twice, with 24 hours between each dose. subcutaneously inject (only). Within seven days of the product being administered to dogs, abortion (or resorption) takes place.


Use AZ Alizin as directed by spraying it 8–10 times in various mouth positions before swallowing. One spray can be used for each nostril in the nose. Do this both before you leave and after you come. Additionally, you can spritz at random when you are in polluted areas or when someone coughs or sneezes close to you.


Since most viruses and harmful bacteria are attracted to environments with hydrogen ions with positive polarity (H-ion +), AZ Alizin Mouth and Breath Oral Spray contains H202 and zinc.

What are the uses of alizin in canines?

Aglepristone, a progesterone receptor antagonist found in Alizin, hinders the hormone required for implantation and placental development and results in abortion a few days after starting the medication.

2. When is Alizin a good choice?

Although we advise waiting until the end of oestrus before using the medicine, Alizin is approved to induce abortion from day 1 to 45 post-mating. This will help you avoid the need for additional courses. Typically, this occurs 10 to 14 days after mating.

3. How effective is it?

The efficacy is 99.9% in the first trimester (up to day 21). Aglepristone affects placental development in the second trimester, and its effectiveness is 95%.

4. How fast is the dose?

5. When does the procedure for an abortion begin and end?

6. What takes place in cases of partial or non-abortion?

If there was a partial abortion or no abortion, a second therapy may be advised 10 days later, between the 30th and 45th day following mating. Considering surgery is also recommended.

7. Teratogenic or mutagen, is alizin?

There is no proof that aglepristone causes congenital defects or mutations.

How late can a dog get pregnant?

Very few situations arise with canines when the female needs to have an abortion to preserve her own health because Mother Nature did a good job with them. In other words, abortion in dogs is more for the owner’s convenience than for the dog’s own needs.

Most frequently, coitus is suspected or shown to have taken place when owners let their female dogs walk off while they are in heat. Most owners will ask their veterinarian for advice and look for a medical way to end the pregnancy if this results in an unintended and unwanted pregnancy.

Some incidences are the result of bad timing on the part of breeders or multi-dog families’ owners. These breeders don’t know when to separate the bitch in heat from their studs, so they leave her alone long enough for her to mate without human intervention in choosing the male partner.

When Is It Best to Abort a Dog’s Pregnancy?

Most vets will advocate for an ovariohysterectomy as a first course of action, but typically just when pregnancy is just getting started (i.e. the first month.) The uterus and ovaries are surgically removed during an ovarian-hysterectomy (watch an explicit video of the surgical procedure here.)

When a dog is pregnant, there are additional dangers to consider: engorged blood vessels, a longer surgical process that increases anesthesia risk, and, if the due date is extremely close, the possibility that the puppies are already completely formed, necessitating their individual euthanasia.

How Late in a Pregnancy Can Dogs Have an Abortion?

Technically, a veterinarian has the ability to terminate a female dog’s pregnancy at any time. However, stronger surgical procedures rather than medicines during the beginning weeks of the woman’s pregnancy may be employed as abortion methods in the last weeks of the pregnancy.

Veterinarians will therefore always advise dog breeders to think carefully before requesting an abortion during the second part of the bitch’s pregnancy.

Can You Give Human Abortion Pills To Dogs?

The issue is not the effectiveness—or lack thereof—of the medications, but rather the absence of medical supervision during the procedure and the potential consequences for the health of the dog or even people. None of these medications are 100% effective, and the most of them have bothersome side effects. Without a follow-up ultrasound or blood test, it is impossible to determine whether the treatment was successful. Additionally, dosage management is crucial to reduce side effects, and a veterinarian almost always has to administer antiemetic and antibiotic medications concurrently to reduce nausea and manage the risk of infection.

Uninformed use of these medications in dogs runs the risk of toxic overdose in pregnant dogs, as well as major issues including pyometra and other reproductive emergencies.

Describe Alizin.

Alizin is a medication that safely and successfully induces abortion in dogs when there has been a miscarriage. It contains a synthetic progesterone antagonist that suppresses the signals necessary for successful ovarian implantation and subsequent pregnancy maintenance. It has no impact on fertility or upcoming pregnancies.

Do female dogs have morning-after pills?

Paradoxically, both “yes” and “no” are the appropriate responses to this query. The more thorough response is that everything depends on your veterinarian, the state you reside in, and the accessibility of the medications in your nation. Just as there are regional variations in the morning-after pill for people. Some morning after medications are referred to as “abortion pills” and are only available in a very small number of states and nations worldwide.

The treatment with either diethylstilbestrol (DES) or estradiol cypionate is the most popular remedy for the morning-after pill for dogs (ECP). Since estrogens typically stop fertilized eggs from migrating and implanting in the uterus, they both rely on estrogen therapy. They are what we refer to as the morning-after pill for dogs, but each one has its own set of directions, health concerns, and safety warnings.

What Does Science Say?

There aren’t many well-controlled clinical studies that demonstrate without a shadow of a doubt that estrogen medication is either safe or effective for ending a dog pregnancy. However, follow-up surveys revealed that dogs getting estrogen-based medicine had higher than average health risks.

While scientists agree that estrogen therapy may be effective, the fact that not all treated bitches were actually bred may be the cause of the mixed results. This puts a lot of strain on the veterinarian’s diagnostic abilities because needless estrogen therapies will have an adverse effect on your pet’s general health.

We must, however, look more closely at the two potential morning supplements for dogs in order to get all the information.

Diethylstilbestrol (DES)

  • It comes in tablet form, and if given to the dog for five days immediately following mating, it has occasionally been successful in ending a confirmed unwanted pregnancy.
  • There is no longer a market for the injectable version of DES.
  • On the market, medications are still accessible.

Estradiol Cypionate (ECP)

  • It is frequently supplied as an injection to dogs to stop the embryo from implanting in the uterus, and it is claimed to be effective if given within 72 hours of the mating.
  • Although the FDA has not approved this medication as a treatment for either dogs or cats, a veterinarian may legally prescribe and deliver it as a prescription extra-label medication.

Similar to how it is with humans, two different dogs do not respond to the same medication in the same way. Your vet should inspect the dog regularly for a few weeks to ensure that the morning-after pill is effective in ending the pregnancy. In order to fix the issue in the event that the treatment is ineffective, he must first determine whether the pregnancy has been ended or not.
