The decision to breed a litter of puppies should be very thoughtful: a total of 109,074 dogs were abandoned, only in 2010. In the event of an unwanted pregnancy of the dog, there are several ways to end the gestation. Sterilization with surgery is one of them, but also certain medications. Knowing your risks and benefits helps you choose the best option.
The decision to terminate pregnancy in litters of unwanted dogs is a responsible option. A total of 109,074 abandoned dogs they were collected by animal protectors and kennels (in the case of kennels, dogs are usually slaughtered within a few weeks) during 2010. They are data from the Affinity Foundation study on abandonment of pets. With this data on the table, preventing a bitch's pregnancy is a serious decision. And in case of being late, it is also to end on time with the pregnancy of the dog in cases of unplanned pregnancy.
There is a false belief when it comes to the pregnancy of female dogs: the idea that it needs give birth At least once in a lifetime. The Madrid Association of Pet Veterinarians dismantles this myth: "No female needs to have offspring for normal development," says the scientific group.
When the female goes into heat, she releases chemical stimulants called urine pheromones. A male can smell this substance miles away. If the game of canine seduction is successful, the couple can then complete the mating.

If the male sperm can reach the ovules of the female dog, fertilization occurs. The pregnancy of the dog begins: a process that will end between 63 and 67 days later with the birth of the puppies.
If the dog's pregnancy was not planned by the owners of the dogs, interrupting the pregnancy at this time seems the reasonable option. If the litter also does not have confirmed adopters, stopping the development of embryos at this point will avoid increasing the sad number of dog dropouts in our country.
Castrate to stop pregnancy
Sterilize A dog is not just an effective way to prevent pregnancy when the decision is made not to raise litters of puppies at home. If the dog escapes, and manages to mate with a dog, it is a way to stop embryonic development.
Surgical sterilization of the female is one of the safest methods to terminate an incipient pregnancy
Dog castration is a simple surgical intervention that involves the removal of the reproductive organs. By removing the uterus of the female dog, embryos attached to its walls are also removed. Sterilization in females is recommended from the year of age, when the dog has already had her first heat.
Surgical sterilization of the female is one of the safest methods for interrupt an incipient pregnancy But as gestation progresses, embryonic growth continues, and the risk for the dog when faced with sterilization surgery increases. In the case of males, the year of age also marks the entry into maturity. That is when the animal can be sterilized and prevent the birth of unwanted litters.
In any case, it is an intervention that must be carried out by your trusted veterinarian. A neutered dog loses interest in getaways looking for a partner And the aggressiveness that some animals possess also usually stops with sterilization. In the case of females, it reduces the probability of developing tumors and annoying psychological pregnancies.
The surgical castration of an animal is a process irreversible. So it is not appropriate in case you have not ruled out raising a litter of our pet in the future. In these cases, chemical treatments should be used.
There is a large number of drugs to interrupt the unwanted pregnancies of the dog. These medications contain hormone inhibitors. progesterone, which is essential for pregnancy. When the activity of progesterone is blocked, pregnancy is stopped with it.
Abortive medication is not exempt from side effects, and can cause vomiting and diarrhea in the dog. Sometimes the animal suffers dizziness, nausea and trembling. The aggressiveness of this medication makes it necessary to consult with the veterinarian, who must follow the pregnancy interruption treatment at all times.

The termination of pregnancy should always be monitored by your veterinarian.
From the first to the third week
Day 1. Whoever arrives before wins. The race that the million sperm released By the male to reach the ovum of the dog is fierce.
The snout of the fetus develops late, despite being a fundamental organ
From the moment when the sperm fertilizes the ovum is when the fertilization. From that moment, the myriad divisions of the newly fertilized cell that will form the body of the future puppy begin to occur.
The journey to the womb, where the embryo will be attached to the walls (this will occur around day 19) to continue its delicate development. The number of future puppies varies: of the eight that, on average, houses the Golden Retriever dog, the two of the small Chihuahua. It is in these first twenty days of gestation when a first diagnostic ultrasound of the same is usually performed, around day 22 you can already differentiate the head and trunk of the embryo.
From the fourth to the sixth week
The cells of the embryos, between two and three centimeters in size around day 28, are, in this period of gestation, focused on forming what will be the puppy body organs, in addition to the muscles and bones. The eyes and spinal cord of the embryo also develop in these weeks of pregnancy of the dog. It is normal, then, for the veterinarian to perform some abdominal check palpations, there is also the differentiation between males and females.
During the second half of pregnancy, growth accelerates and true fetal body development begins. By day 30 the incipient main organs will already be present in the future puppy. Even the heart has begun to produce its first beats, and the limbs begin to grow. This is also the most delicate moment of pregnancy. The dog's body could decide to discard the fetuses after weeks of development.
If at this time, or at any other time during pregnancy, abnormal vaginal bleeding is observed, urgently go to your veterinarian since, if it were a spontaneous abortion, your dog will need special care and be monitored to avoid adverse side effects in the animal.
From the seventh to ninth week
Growth continues its course. Puppies gain weight and take the nutrients they need through their mother's placenta. Around day 55 we enter the final stages of its development. The fetuses already they look similar to what they will have outside the belly maternal. The snout, responsible for the extraordinary sense of smell of the dog, develops late: in the last third of pregnancy.
The hair then appears, which owes the varied color combinations of the coatings to the mixture of two unique pigments: black and yellow. The puppies already have legs and mustaches and, in this phase, his temperament also develops: hormones Present in this process will greatly mark your personality.
As the time of birth approaches, the kicks and jerky movements of the children are noticeable to the naked eye through the mother's abdomen. Puppies ready and ready to be born.
The great moment of childbirth will come from day 63. The puppies are almost completely formed. Their eyes remain sealed to prevent irritation of the urine they expel in the amniotic bag. It will take a week or two to open them completely, but by then they will be out of the womb.
Labor is coming
The moment of delivery should not, in any case, be ignored. The dog must have a quiet environment without strangers, people and animals outside the house, that can alter the normal birth of the animal. It will influence the proper progress of the same, without a doubt, that adequate food has been observed during the pregnancy of the dog.
A matter at all baladí and that can eliminate many of the problems of a good childbirth and the postpartum is the paridera preparation. It consists of the manufacture of a square or rectangular box, of a size large enough so that the dog can stretch in it comfortably and on space for the whole litter, we must avoid at all costs that the dog can crush the puppies when lying down
The sides of this paridera must have a height that prevents the puppies from jumping outside, but also does not prevent the dog from entering and leaving without difficulty.
The environment and place of delivery must be the most appropriate
The dimensions of this space will therefore depend on the breed of the dog. It is advisable that the bottom is padded with towels so that the dog and the puppies are more comfortable and avoid the direct cold of the ground, they can be changed when they get dirty without difficulty.
In addition to all these cares, the moment of breastfeeding begins, which will require certain special care of both the newborn puppies and the new mother.
Remember that your dog's pregnancy must always be followed by a veterinarian.
The food and care of the future mother must be appropriate to her condition.
If you notice abnormal bleeding at any time during pregnancy, go to the veterinarian: it could be a miscarriage.
Take care of the environment and it is space for the birth of the dog: prepare a paridera.

If a female dog has experienced an abortion, the most common symptom is abnormal and widespread vaginal bleeding. An expelled fetus can be found if this occurs in the last trimester. The most common known cause for a miscarriage is fetal death due to hormonal imbalance.
Some types of common causes of miscarriage in female dogs are:
* B. Canis - This bacterium is extremely widespread among dogs placed in a kennel, since it can be easily transmitted. This disease causes both dead births and conception failures. This is usually characterized by prolonged vaginal discharge and may occasionally be accompanied by complications such as arthritis (spondylitis) and inflammation of the eyes (uvetis). Also, it is common in female dogs to have the bacteria in the bloodstream (bacteremia) for up to 18 months after spontaneous abortion.
* Fungal Abortion - This fungus most commonly causes excessive bleeding in the uterus and can lead to an aborted fetus.
* Fetal Death - If the dog has a hormonal imbalance this can lead to the death of the fetus, either causing a dead birth or a miscarriage.
* Neospora Caninum - This is a parasite that is usually found in dogs. This can be transmitted if the dog ingests water, contaminated food, feces or meat from infected animals.
Diagnosis and Tests
Standard blood tests can be used to detect the presence of parasites or B. Canis. If the loss of pregnancy is due to another reason, an abnormal amount of discharge will be noticed. A veterinarian can use ultrasound to detect a viable pregnancy, or to look for any remains in the womb of the dog after malparto or termination of the pregnancy. This is because the dog's uterus will usually be unable to effectively expel all the pregnancy material itself (that is, placental tissue), leading to infection or internal bleeding.
Treatment and Care
For bitches that have undergone a miscarriage due to a bacterium or a parasite, a veterinarian will diagnose the condition and offer a variety of options for medical treatment. Additionally, the dog must be carefully monitored for signs of a more serious medical condition.
Coexistence and Management
Following an abortion, there may be a great deal of discomfort and / or some vaginal bleeding or abnormal discharge. There are many cases where a long-term bacterial problem arises. Pet owners should carefully observe their dog's behavior to ensure that serious problems do not develop as a result.
You want to control your dog's reproductive life and prevent unwanted puppies from being born, but you're worried because:
- He has escaped while still I was in heat and there is a risk that they have mounted it
- The male size was too big for her
- The bitch is too young or too old and the pregnancy can be risky
You should know that your veterinarian has modern and effective methods to interrupt a possible pregnancy.
Your veterinarian will inform you of the most appropriate time. In general, the most practical thing is to treat your dog after finishing the heat but without letting many days go by. In this period, the greatest efficacy is obtained with minimal side effects. Your veterinarian can also perform, if necessary, a later treatment with good efficacy and safety. He will inform you of the time limit for action. If the dog is in an advanced state of pregnancy, abortion can cause certain clinical manifestations. They are not serious but a little more annoying.
In both cases, you must return to the clinic when the veterinarian tells you to complete the treatment.
In many cases, none. Although it could happen that.
- The dog frequently licks her genital area and gradually ingested the removed tissues.
- Let's see a vaginal discharge, more abundant and consistent.
- That may be depressed or without appetite for a few days.
- Be excited or gasp and cry.
Yes. Anti-hormones have the advantage of not altering reproductive capacity. They do not increase the risk of uterine infections in the dog and do not modify their fertility. The dog may return to heat between 1 and 3 months after treatment, that is, earlier than normal.
If the abortion is performed while the dog is still in heat, new amounts should be avoided during or after treatment because the bitch could get pregnant again. That is why it is safest to wait for the fertile period to end.
The delicate balance of a pregnancy
The belly The mother's mother works as a delicate, but complete, universe for embryos that develop inside her. Fetuses are not self-sufficient and feed on the nutrients present in the dog's body.
The miscarriage is more visible and painful for a dog who suffers from her fifth week of pregnancy
That complex universe that is the belly of a pregnant bitch is maintained thanks to an endless number of balances and chemical reactions that allow fetuses to have the right food and conditions they need for their development.
During the first two weeks of gestation, the embryos have not yet reached the walls of the dog's uterus, to which they will be anchored to finish their growth. Floating embryos depend entirely on the maternal fluid and its complex balance of chemical and biological reactions. Any alteration that makes this universe an uncomfortable place can cause embryos to not survive.
The most delicate moment
During the second half of pregnancy, the growth of embryos inside the mother's womb accelerates. By day 30, the fundamental organs begin to grow. Even their hearts begin to beat. It is also the moment delicate of pregnancy, when more irrigation exists that the dog undergoes a miscarriage.
If the loss occurs before the fifth week of gestation, it is possible that the dog's body reabsorbs to the embryos, so that the only thing left of them are visible lumps in the belly of the dog.
The death of the embryos in these early stages of the gestation of the dog usually goes unnoticed, and the animal does not have to suffer damage. It is even possible for the abortion to take place before the veterinarian has confirmed the pregnancy. Which explains that these early losses are usually related as a cause of infertility of the dog, rather than as an abortion to use
Even with losses, the pregnancy of the dog can continue. The death of one or more fetuses does not always mean that the pregnancy has ended. Embryonic development can continue and end the birth of some of the healthy puppies at the end of the nine weeks of gestation.
Abortions after five weeks
The miscarriage is more visible and painful for a dog who suffers from her fifth week of pregnancy. The most obvious indication that something is wrong is the appearance of an unexpected bleeding in an abundant amount. The expelled fluid may have shades of greenish brown characteristic of the maternal placenta pigment. This bleeding may include fetuses expelled by the dog's body.
In addition to the blood, the sudden contraction The dog's stomach reveals a problem. This narrowing causes discomfort and pain. Along with the external signals, the dog that loses her pups in this last stage of the sick gestation. The animal may appear tired and depressed, suffer loss of appetite, dehydration and even some fever. Vomiting and diarrhea are other symptoms of a female dog who has aborted.
Reasons for abortion
The most common cause for a miscarriage in the last stage of pregnancy is a hormonal imbalance inside the belly of the dog. Embryos depend entirely on this medium and the mismatches end the death of fetuses.
The presence of the bacteria known as Canis brucilla It is another reason that explains unexpected abortions in female dogs, especially in animal shelters as it is very contagious. The parasite Neospora caninum, present in water and contaminated food and some fungi, can also cause miscarriages in our pet.
Monitor the presence of parasites and bacteria in your pregnant dog. Blood tests help make a quick detection.
Abnormal and heavy bleeding may warn that the dog suffers an abortion.
A dog who suffers a miscarriage because of an infection of parasites or bacteria should be treated.
Remember that abortion can cause discomfort and pain in the dog, which will be sick and depressed.
What to do if we suspect that our dog misbehaves her pregnancy
The first thing to do is submit our female dog to veterinary reviews for the professional to control pregnancy. Despite the precautions, a Abortion which, as in people, can be due to various causes: death of puppies, bacteria, abnormalities, hormonal problems, accidents, parasites, etc.
Other times, if there are risks due to the poor health of the animal, or at its age, the veterinarian can advise interrupt pregnancy. The ideal is to do it before the month and a half of gestation. In this case, after examining the dog by ultrasound and analysis you will know the state in which it is.
The usual method is to give the dog, in a very controlled way, two injections that usually contain different doses of antiprolactins, corticosteroids or antiprogestins. The process does not usually have side effects and the animal can go home.
The symptom that betrays that a dog has suffered an abortion is the usual vaginal bleeding.
