How much time does a dog's pregnancy lastand how to find it
In dogs, the average length of pregnancy lasts from 61 to 66 days, in other words, about two months. In some cases, due to individual characteristics, bitch can go pregnant for a little longer, up to 72 days, or, conversely, a little less, 57 days. In the very early stages of pregnancy, which lasts up to and a half weeks after coagulation, it is practically impossible to diagnose the condition of the dog by external manifestations. The position of the dog becomes apparently noticeable only in the second month.
Signs of pregnancy in dogs can be manifested very shortly before childbirth. Nevertheless, indirect signs of a dog's position can give you knowledge about yourself two weeks after conception. The dog may become sleepy, apathy and sluggish. However, the changed behavior of the animal is not a clear indication of pregnancy.
Therefore, in this situation it is best to go with a dog to a veterinarian who, using modern methods of examination, such as ultrasound, will quickly make an accurate diagnosis. A visit to a vet should be done after a bundle, regardless of whether the dog began to behave differently or not. Because early detection of pregnancy will ensure the timely taking of appropriate measures.
Detection of Dog Pregnancy by Using the
Test A test of whether a pregnant dog or not, can be done in many veterinary clinics. The essence of this procedure is to analyze the blood of an animal in order to establish the amount of relaxation hormone in it.
Two or three weeks after conception, the concentration of this substance begins to increase, which is manifested in a laboratory study. If such a test is performed during the third or fourth week of pregnancy, then its results have almost 100% confidence.
How Pregnancy Is Detected Using the Ultrasound
If from the time the bundle lasts from 24 to 35 days, then the pregnancy of the dog is uncertainly determined using ultrasound or ultrasound. During this period of pregnancy on the screen are clearly visible amniotic bubbles, within which there are embryos. However, the exact number of embryos at this stage of pregnancy with the help of ultrasound does not appear. Only 38 or even 45 days will be able to determine how many puppys are born in a dog.
In addition, using ultrasound in these terms, you can not only make a prognosis of pregnancy and determine the extent to which embryos are viable - this method of research even allows you to assess the state of the internal organs of the offspring of the dog. If the pregnancy proceeds safely, the embryos have a clear heartbeat, in addition, they exhibit normal mobility.
In some cases, pregnancy becomes detectable by appearance at the end of 1 month - there is a swelling of the skin of the mammary gland, becoming clearly marked nipples. Sometimes the dog even grows stomach. But such signs in the early stages - rather an exception than a rule.

Dog and Health Diagnosis
During the second month, the pregnancy of a female becomes unequivocally diagnosed on the basis of external manifestations, and no longer needs to be carried out in any clinical studies to determine whether a pregnant bitch orNo.
The fact that the animal is in a position indicates the following series of characteristics: the
- animal becomes complete;
- there is swelling and enlargement of the mammary glands;
- significantly increases in stomach size.
3 weeks before delivery, the most significant increase in animal weight is observed. In the period between the 38th and 45th day after conception, you can even test the fruits in the womb. However, in the absence of the appropriate experience alone, this can not be done, otherwise it is possible to accidentally injure both the fruit and the dog itself. At 48-50 days you can determine the exact number of fruits by X-ray examination.
If the dog gets pregnant for the first time, then the lactation begins immediately after delivery, or several hours earlier. If the dog has already posed offspring, then milk can appear even after 40 days after conception. The norm is the appearance of milk a week or ten days before childbirth.
In the diagnosis of pregnancy and the calculation of the approximate time of labor, rectal temperature is of considerable importance. If the fruits develop without deviations and pathologies, then in the early period of pregnancy this indicator is within the normal range. There are noticeable jumps of rectal temperature in the week before delivery. For a day or at least eight hours before the birth, basically, there is a sharp drop in rectal temperature. In large animals, the rectal temperature can drop to 37 degrees Celsius. In a small dog, this indicator can fall to 36 degrees. When the dog has already become old, the value of the rectal temperature returns to normal.
Changing the Condition of a Pregnant Dog
Below, details detail the changes that occur with the dog and its fetus over time. These data refer to Rhodesian ridgebacks, and therefore for dogs of other breeds may vary. Therefore, the following information can act only as a benchmark, but not the ultimate truth.
Day 1 of
On this day a dog is knitting. Conviction does not guarantee conception, the necessary condition for which is ovulation - the output of the egg from the ovaries in the fallopian tube, where the merging of the sexual cells occurs. If ovulation did not occur on the day of coagulation, the eggs can be fertilized and in the following days, because if spermatozoa are normal, then they, while inside the uterus, can remain active for up to a week.
Day 2 of
Dogs re-knit to increase the likelihood of conception.
Once inside the fallopian tube, the sperm connects with the egg with the formation of zygotes. The first days of conception do not affect the behavior of the animal. Therefore, feeding and walking a dog needs the same plan as before. Physical activity of the animal should not be limited, however, in the heat it is impossible to prevent it from overheating.
During this time, zygotes move in the fallopian tubes to the uterus, which reach about until the 11th day. Embryos are enclosed in 3 embryonic shells. On the surface of the outer membranes are fibers used by the embryos to penetrate into the uterine mucosa. Where the mucous membrane of the uterus is connected to the external embryonic membrane, a placenta is formed.
This is the beginning of the development of the embryos. By the end of this stage, the division of the embryo into the head and body occurs. In addition, at this stage, the vertebral column is formed and the central nervous system is formed. For owners, the most responsible period begins, since any adverse effects on the animal can cause the pathology of the development of the fruit. It is necessary to remove from the life of the dog all the negative factors of physical nature, as well as emotional stress. During this time, any changes to the animal are adversely affected by the animal, so the daily routine and food intake should be left unchanged. It is highly undesirable to change the place of residence of the dog.
In addition, the following procedures are excluded:
- prophylactic vaccinations;
- treatment of dogs with chemical agents against external parasites.
At this stage, there appear the first external symptoms of pregnancy, namely:
- , some enlargement of the nipples, while taking a pink tint;
- is some sort of hair loss on the surface of the abdomen and, in particular, near the nipples.
In embryos, the development and consolidation of internal organs takes place.
At this stage, the embryos undergo the following changes:
- forms placenta;
- begins the formation of the heart;
- begins the development of the liver;
- is formed by a spine;
- distinguish and develop limbs;
- appear jaws, ears, eyes and nose;
- is the teeth tab.
At the present stage, the dog noted the following series of symptoms:
- , lethargy and mood loss;
- loss of appetite;
- nausea in the morning, in some cases it comes to vomiting;
- occasionally appear scalene vaginal discharge, transparent or colored egg protein.
During this period, it is necessary to begin to introduce gradual changes in the mode of feeding the animal. Meals should be made more often than usual, but portions should be reduced.
At this time, pregnancy is well diagnosed by ultrasound. At first, only embryonic bubbles can be seen, and the embryos themselves are invisible.
By the beginning of this period, the embryos reach the size of the walnut. In their organisms, the process of hardening of the cranial and maxillary bones begins due to their impregnation with calcium salts. By the end of this period in the embryo, the eyebrows, nose, chin are covered with sensitive hairs or vibris. Embryos can be felt with your fingers, but only experienced specialist can do it. The physical activity of the dog must be reduced to avoid trauma to the fetus.
This is the beginning of the second term for carrying dogs of her offspring. At this stage the stomach of the dog becomes larger. By the end of the period there are significant changes in the behavior of the animal. It behaves quietly, with it increasing sensitivity.
The animal appetite intensifies and the diet should be fully consistent with its condition:
By the beginning of this period, the weight of the fruit is 20% of the mass of newborn calves. During this time their intensive growth takes place. There is a strengthening of the bones of the ribs and extremities.
At this stage, the fruits grow faster. It includes the following changes:
At this time, the fruits are missed by palpation, but it is still impossible to accurately determine their number. The uterus of the animal increases so much that it occupies more than two thirds of the abdominal cavity. Breast glands significantly increase, the wool in the area of the nipples falls out.
At this stage, during the day, the dog should be given 15-20% more feed than usual. Feeding should be done in small portions, at least three and not more than five times a day.
During this period, the dog can not run, jump, and make sharp movements.
At this time, the fruits of the pelvic bones are formed and the wool continues to grow.
By this time the dog grows considerably. Its abdomen is greatly enlarged, and fruit movements are noticeable. If a dog carries off offspring is not the first time, it can appear drops of milk on the nipples.
There is anxiety in the behavior of the animal. The dog is already looking for a place where it will give birth, and therefore the owners need to prepare such a place in advance and begin to accustom an animal to him.
By the end of the period, the dog relaxes a lot and often nipples.
Sometimes in this period the animal may become worse or even lose appetite. Despite this, it is necessary to feed it often, in small portions, increasing the amount of food supplied during the day, by 25 or even 50 percent.
At present, the weight is already 75% of the mass of newborn puppies.
As the dog's pregnancy lasts for a long time, with normal development at this time, the fruits are already completely formed, covered with hair and are ready for appearance. A dog can start to give birth at any time, and therefore the hosts should be in constant readiness to take delivery. The dog needs to measure the temperature in the morning and evening. If the temperature has dropped by 1-2 degrees, then after 8 hours, amniotic fluid may diverge and re-starts. Therefore, it is already necessary in advance to prepare the appropriate means and medicines. Another sign of the approach of labor is the abandonment of animal food, which usually takes place 12 hours before the take-over.
Puppies are born alternately, at some intervals. If intrauterine development is normal, then they appear on the world with coated hair and with their eyes closed. After birth, the puppies must be cleaned of the placenta and carefully rubbed.
