Pregnancy is always an exciting experience for any living being. Having a pregnant dog can be a joyous event for any dog owner, one that comes with great responsibility. The dog’s health and that of its puppies are so important that every dog owner should be aware of dog pregnancy stages and nutritional requirements before it even happens. A dog owner should know how to act at all times, although often visits to the vet are needed. The pregnancy of a dog lasts up to 9 weeks, approximately 63 days. However, a dog could give birth before or after that period of time, between 58 and 68 days. As the puppies grow in the womb of their mother, proper medical care is required in order to ensure a healthy birth. To do this, a dog owner should study the anatomy of a dog and pregnancy itself according to the breed of the animal he or she owns. Like any pregnant female, a female dog requires a lot of care, love and affection during pregnancy. Remember that the first stage in the pregnancy of your dog will be the gestation. There are no clear symptoms to diagnose pregnancy in dog right after it happens. Thus, a dog is likely to show signs of pregnancy only after the first 25 to 36 days since mating.

Some people choose to arrange a cozy place in the comfort of their own home for the birth, while others prefer to take their canine pet to the vet, where all the needed conditions are already met.

4 pregnancy stages in dogs

How long is a dog’s pregnancy? Just as in humans, there is a period of a few days in which a dog could give birth. As said, the standard period is 63 days, but there are a few female dogs that are actually going to give birth after exactly 63 days since insemination. Expect for your dog to be ready for birth between 58 and 68 days since mating. During 9 weeks, plus or minus 5 days, a dog that carries puppies has to go through 4 phases, all which are natural and require different care and attention from an owner. The first phase lasts for 3 weeks and is not really noticeable because the dog does not show any signs, except maybe a little fatigue or a slight loss of appetite. The second phase lasts from the 4th to the 6th week. That is when a caring and observant dog owner may notice weight gain and increased size of the dog’s nipples. The third phase is when the growth of the dog’s womb becomes impossible to miss. Also, the production of breast milk begins. As for length, this phase lasts until the 9th week of pregnancy, when labor should be near. Last, the fourth phase is the shortest one and the most eventful one as well. The dog becomes restless and starts to seek a quiet place where it can give birth. Measuring its body temperature is a great way of finding out when it is due. Its temperature drops significantly when it is about to give birth.

Body changes in pregnant dogs

In order to follow the canine pregnancy calendar, one has to make a note of the day when the dogs were mated. Fertilization occurs in the oviducts after 48 to 72 hours since mating. After about 10 to 12 days, the eggs become fertilized and are implanted in the uterine wall. Gradually, the embryos become blastocysts. After 14 to 15 days, the dog’s nipples begin to grow a little and develop a darker pink tone. Gradually, the skin from the dog’s abdomen and that around its nipples becomes thinner. It is in the first 20 days of pregnancy when the first ultrasound can be performed, which shows the head and the body of the embryos from the dog’s womb. All the other changes become visible after a period of approximately 30 days. After a month since insemination, a dog’s embryos will be walnut-sized and the veterinarian will be able to figure out how many puppies are inside its womb. The muscles and the bones of the puppies are forming during this period, as well as their spinal cords and eyes. That is when you should begin to increase food rations or their frequency, keeping in mind that too much food will only enhance its weight gain, which is not recommended if it goes out of control and which could lead to complications. The abdomen of the dog will become larger and very visible. From the behavioral point of view, the dog can be a little restless and wander from place to place, looking agitated. After six weeks, it might lose its appetite once again. However, you should continue feeding the dog throughout the day. After two months since insemination, the puppies’ hearts beat on their own and their limbs are almost fully grown. You can clean the dog’s nipples and vulva gently with a clean cloth and warm water. The first sign indicating that the dog is about to deliver is when its rectal temperature drops to 98 degrees. Another indication is when there is a discharge of clear liquid from the dog’s vulva. About 14 to 24 hours after that happens, you could be delivering its puppies. Some puppies born before the normal gestation period ends may not survive because their organs might not be fully developed and prepared to function in the outside world. If that happens, you should try to save as many as possible. This is also the most delicate moment of a dog’s gestation. The body of the dog may decide to dispose of fetuses after so many weeks of development. If at this time, or at any other during pregnancy, you observe an abnormal vaginal bleeding, you should urgently contact the veterinarian as that could be a sign of abortion and the dog will need special care and should be monitored in order to avoid the occurrence of adverse side effects. Some dogs might even eat their puppies after birth because of something called puppy cannibalism, which occurs rarely and from multiple reasons.

Ultrasounds and x-rays for mother dogs

In order to establish the dog pregnancy timeline, you can resort to ultrasounds and x-rays. In case you are not aware when the dog you own got pregnant, then you can rely on an ultrasound. It is a great option because with its help, the vet can also evaluate the pups in development, their heart rate, movement and he or she can calculate the time of pregnancy in order to be ready for the arrival of the puppies. The gestational ultrasound can be performed starting with day 18 after the insemination, until the end of pregnancy. It is a really quick test that can provide valuable information in a few minutes. X-rays are very important, especially for dogs that are pregnant for the first time. An x-ray can show exactly how many puppies are inside the dog’s womb and also whether they may or may not pass through their mother’s birth canal. If their skulls are larger than their mother’s birth canal, then their mother will need a cesarean. This is not the only reason because of which a pregnant dog might need a cesarean. The puppies might also be in wrong positions or the mother may not have contractions at all. The radiographic study can be performed starting with the 45th day of gestation, but it is recommended between day 50 and 55. The radiation from an x-ray presents no risk for the puppies or the mother.

Nutritional needs of a pregnant dog

Just as any dog, pregnant dog needs fresh water available at all times. Before mating, the dog should be fed with a food especially made for adult dogs. After it becomes pregnant, you can continue to feed it a normal amount of food of high quality. Puppies grow very little during the first 4 to 5 weeks of gestation, so the dog will not need extra nutrients. Feeding the dog too much during pregnancy will only make it fat and it will be unable to deliver without complications. During the last 3 to 4 weeks of gestation, puppies grow rapidly. Therefore, their mother needs a higher intake of nutrients.  During this period of pregnancy, the mother’s body weight dog will increase progressively up to 25-30%. Choosing food with more protein or food especially made for pregnant dogs would be ideal. The mother’s appetite increases starting at the end of the first month. The female dog could have between 2 and 8 puppies inside its womb, which means that it has to provide enough nutrients for the development of their bones, muscles and nerves. Corn is often an element of bulking, which does not really bring a qualitative contribution to the dog, so avoid products that contain it. In addition, these foods are not always ideal because they are difficult to digest. Food for junior dogs is recommended for pregnant dogs too because they contain a high quantity of proteins. Remember to choose the best brand you can find. The appetite of a pregnant dog can be capricious. It might refuse to eat what it ate before and eat what it previously refused. Regardless of what it wants to eat, it should also take supplements rich in calcium and different vitamins, such as vitamin C and vitamin D2. The vet will recommended the exact supplements after an initial consultation. The vet will also recommend 30 minutes of slow daily walking for your pregnant dog. In case of female dogs used as police dogs or watch dogs and so on, they are not supposed to be on duty after the first month of pregnancy.

Signs of labor in pregnant dogs

The following changes are considered signs that labor approaches in pregnant dogs: swollen vulva, tail becomes more mobile and milk or colostrum appears. The female dog tries to find a safe place in the house when it can give birth. Within 24 hours before the birth, a dog’s rectal temperature drops to 98 degrees. As a dog owner, you must prepare a box that is clean and where you should put the dog before it goes into labor. That is where its puppies will live for the first 4 weeks of their lives, so take your time finding a perfect fit. The actual labor begins with uterine contractions that are becoming more intense and that can be observed by looking at the dog’s belly. Approximately one hour after the expulsion effort opens the birth canal, the fluid bag breaks. In more common terms, this means that its water broke. Very soon after that, the first pup should come out. There should be a break between 10 to 30 minutes between births. The pups come out covered in placenta, which is eaten by the mother after cleaning the pup. If the expulsions are too fast and the mother does not have time to lick every puppy, the placenta can be gently removed with a towel. One should also cut the umbilical cord and use tincture of iodine to disinfect the cut. Some female dogs might not have maternal instincts at all, so one should know how to take care of everything. Fetal fluids might be greenish, but that is normal, so don’t be alarmed. After the dog gives birth, it will also eat its placenta. That is a good thing, so no one should try to stop it. It eats the placenta because it contains a large amount of hormones that contribute to the uterine involution and the onset of milk secretion. After the whole process is done, you can reward the mother with a glass of milk and let it recover from the tremendous effort that she made by giving birth to up to 8 puppies. Depending on the number of puppies, this process can last up to 10 hours. It goes without saying that if something goes wrong the vet should be immediately called for assistance.

Advice for every gestational stage

If you suspect that your beloved pet is pregnant, you should make an appointment to see the vet. He or she will perform routine tests and clinical tests in order to assess your dog’s health state and let you know if you are going to have more puppies or not. If your suspicions turn out to be true, then the vet will perform further tests in order to make sure that everything is fine with the future mother. He or she might tell you the stage of the dog’s pregnancy or might require an ultrasound in order to find out more details. This visit is important because there might be pregnancy problems you know nothing about and only a specialized person can notice and handle. During gestation, the dog should receive the same care as usually. It is recommended for pregnant dogs to be brushed daily, regardless of the length of their fur. This advice applies for the period after birth as well. This is the safest way to keep infections away and to avoid skin problems that might complicate the pregnancy. It goes the same with bathing. However, contact with other dogs should be limited. If you are a multiple dog owner, then you should make sure that all your other dogs are in top shape, healthy and clean when they interact with the pregnant one. The health of a pregnant dog should be monitored throughout its gestation period. In the first few weeks it may experience nausea and it might not want to eat as much as it used to. These aspects should not alarm you, because they are completely normal. However, if you notice that it does not hydrate for 24 hours or more, then you should go visit the vet. In addition, you should check its temperature constantly and look for signs of listlessness on a daily basis.
