Pregnancy of dogs by day: detailed calendar

Pregnancy of a dog for any owner is a crucial moment. At this stage, the development of future charming puppies. Therefore, it is very important to know about the pregnancy of dogs by day, so as not to harm and properly take care of their pets. The darling in the position requires special care and supervision of the host, which largely influences the outcome of the forthcoming birth. The article considers such issues as duration, signs and symptoms of puppies, as well as a detailed pregnancy calendar, divided for convenience by week and by day.

How many days does the dog have a pregnancy?

A normal puppy can last from sixty to seventy days. However, viable kittens are able to appear on light and on the 58th day. Birth before this period is already considered pathological. The cause may be a latent disease, trauma, an old or too young organism, excessive obesity or exhaustion.

Late births up to the 72nd day are also considered normal. This is due to the individual characteristics and dog breed. If your pet has not reached this deadline and is already starting to go 73 days, then there is an occasion to contact the veterinarian. He will conduct an operative intervention - caesarean section - and help the kittens to be born.

What determines the timing of pregnancy

Above it has already been mentioned, on what depends, how many days does pregnancy in dogs last. However, this is not all the reasons, and there are a number of other factors. The first pregnancy usually proceeds unpredictably, therefore to define exact term will be difficult at primigravarnyh dogs. Also strongly influenced by the breed, weight, size and number of puppies in the litter.

Pregnancy of small dogs (terriers, bolonok, Pekinese, griffins and levreets) on average lasts sixty days. In this case, they can tolerate from two to four puppies. In the womb of large-breed dogs (Doberman, Dalmatians, St. Bernards and Mastiffs) can be up to fifteen fruits. Childbirth occurs on the 65th day. Although there are cases that it occurs on the 55th or 74th day.

It is also necessary to take into account the regularity: the more puppies in the womb, the longer the pregnancy will last and vice versa.

Why such a small gestation?

Pregnancy of dogs on days is sixty-seventy days. This is very little and unusual for a person. However, the nature of this phenomenon has an explanation.

Dogs of their origin belong to the class of predators. And beasts-meat eaters nurture their offspring for a rather short period - from two to three months. Predators follow the principle of survival in nature. A pregnant dog is difficult to hunt, and this can deplorably affect her and her offspring. It is much easier to take out kittens at short notice, hide them and feed them in the lair.

Behavioral symptoms of swallowing

In the first month, pregnancy in dogs is still imperceptible, but the attentive owner will be able to determine the interesting situation of his pet for behavior. Beginners should note the pregnancy of the dog by days, take notes in the notebook in detail.

In the early stages, pay attention to the appetite of the pet. Usually, pregnant females lose appetite in the first month of bearing fruit and eat less than usual. However, not all dogs lose interest in food, and not always this is an indicator of pregnancy. In the second month, the appetite again sharply increases.

At the first weeks of puppies, the pupil can see apathy, lethargy, slowness, a desire to sleep more, ignoring the host's commands. But this can be considered an indicator of pregnancy, if your dog before mating was always energetic and playful. The pet in the early stages can become excessively sociable and affectionate. However, there is an opposite situation, when the dog is looking for solitude in secluded corners.

Signs of a dog's pregnancy by days

Determining pregnancy by behavior is an unreliable method. It is better to rely on physiological signs, which depend on the term.

So, on the twentieth day it is already possible to diagnose the puppies with the help of an ultrasonic device and see on-screen amniotic blisters with embryos. By the end of the first month (at 25-30 days), the skin in the nipple region swells, and the mammary glands themselves become pink or clearly visible. Behind the ribs you can see a noticeable increase in the abdomen.

After the thirtieth day, there are already obvious signs of pregnancy. The mammary glands strongly swell, the weight and abdomen sharply increases. On the sixth-seventh week of pregnancy (this is between the 38th and 45th days) in the uterus, you can feel the individual fruits, distinguish between the bones of the skull and the rib of the embryos. In this period, using an ultrasound machine, you can already find out how many puppies will be. This information is important to know when a large litter. It will be useful to take with you a notebook with notes on puppies, because a specialist can ask about a dog's pregnancy by days. Photos of the abdomen from the X-ray you see above, you can take such a picture from an ultrasound specialist.

Ten days before the end of the period, the already given birth of dogs appears milk. At the first pregnancy it is formed a few hours before delivery or right during them.

First week of longevity

In the first two days after mating, the spermatozoa move to the eggs for their fertilization. On the third day they pass into the fallopian tubes. On the fourth day, the fertilization of the eggs takes place. At the end of the first week, the zygotes fall over the fallopian tubes into the uterus and are covered with "embryonic membranes".

There are no special changes in the behavior of the dog. Therefore, there is no need to change the exercise schedule, the feeding regimen or limit in activity. Nevertheless, you need to make sure that the darling does not overheat for a walk and does not feel thirsty. This is extremely undesirable for a pregnant dog.

In the first week, morning sickness can serve as a sign of schizophrenia. However, this is not a reliable symptom. It is more reliable to regularly check the body temperature of the female and monitor the changes. It would also be nice to have a diary, which will help control the pregnancy of the dog on days.

Discharge from the vagina of light pink often scare inexperienced owners. At this stage, this is considered the norm, and there are no reasons for concern.

What happens at the second and third weeks

At the beginning of the second week embryos are fixed in the mucous membrane of the uterus, which forms in the placenta. The embryos on this period in size do not reach even a millimeter. On the fifteenth day a new stage of intrauterine growth begins: the vital organs of future babies are developing. From this moment it is very important to closely monitor the condition of the dog, as everything that is going on will affect the formation of embryos.

On the sixteenth-seventeenth day, the embryos grow to one millimeter. They form a body, spine, head and central nervous system. In the period from the eighteenth to the twentieth day internal organs develop. Embryos increase in size to four millimeters.

At the end of the third week (on the 21st day), the heart is formed. The size of the embryo is already half a centimeter, but this is not enough to see the emerging kitten on ultrasound. But you can still diagnose pregnancy: on the screen will be visible fruit shell. At this stage, the owner should control the appetite of the dog. Malnutrition and, as a result, a lack of nutrients will damage future puppies.

From the fourth to the fifth week

During this period, you need to closely monitor the pregnancy of dogs by day, since already from the 22nd day you need to change the feeding regime. Your pet can refuse food because of morning sickness, so it is better to offer food often, but in small portions. From the 23rd day the embryo grows to a centimeter, it develops eyes, nose, ears, jaw and liver. On the 25th day you can trace the formation of teeth, limbs and spine.

On the 26th day, the embryo is already about the size of a walnut, and an experienced veterinarian will be able to diagnose whelping with abdominal palpation. A dog is recommended to limit in active games, so as not to harm the fruits. From the 27th to the 31st day, "calcification" occurs in the area of the skull and jaws. Since the 32nd day there has been an intensive growth of future kittens, so it is worth introducing more protein into the dog's diet.

Sixth-seventh week: pregnancy is obvious

In the period from the 36th to the 43rd day, the development of embryos is accelerating. Primary sexual characteristics appear , blades, fingers are formed and wool grows. The size of future kutis reaches 6.5 centimeters. On the 44th day, the dog's uterus grows and takes up most of the abdominal cavity. Puppies can already be palpated, but it is difficult to determine their exact number.

It is recommended to increase the amount of food by 20%, to offer portions more often, but to make them even less. This has a good effect on the pregnancy of dogs. By days and hours you can paint a diet to simplify your task and not to rack your brains, how to feed your pet. On the 47th day the future mother begins to seek shelter for childbirth and most of the time she lickes her nipples. It's time to make an aviary or equip a part of the room and gradually accustom to this place the dog.

Last weeks of pregnancy

From the 50th to the 57th day, the fruits are already fully formed and grow from 12 centimeters to 15. The future mother mostly lies and licked, and in the abdomen you can see the movements of the puppies. On the 58th day, if you press the nipples, then milk will appear.

On the 59th-62nd day you need to be ready for childbirth, they can start at any time. Stock up with the necessary medicines and equipment. In the morning and in the evening measure the temperature. The day before birth, it drops sharply.

On the 63rd day the amniotic fluid flows, the cervix opens. The next day, hormonal changes occur. The uterus shrinks forcefully, causing fights. Puppies are not born in a row, but at small intervals.

Be sure to use this pregnancy calendar of the dog on the days when your pet will be in position. And do not leave it unattended, at any time the veterinarian may need help.
