How can we tell if a dog is pregnant?

When the owner of the dog decided to let their dog do the mother, and then carried out a series of breeding to preserve the fetus, and so on, but the dog belly without pregnancy symptoms? Don’t worry, here are some ways to help you with how to tell if your dog is pregnant.


1. Pregnancy:

An average of 63 days, up to a maximum of 72 days, from the time the dog is first bred; if less than 58 days, the resulting litter will not survive.

2. Pregnancy diagnosis:

(1) External observation

In general, the teats and the skin of the base of the pregnant bitch were slightly red after 15 days of breeding. After 20 days, vomiting, loss of appetite, and dejection occurred more often. After 1 week or so, appetite increased greatly, but some partial food, the action became steady; 30 days or so breast gradually sagging, flexible nipples; 35-50 days, before the abdomen gradually expanded, easy to breathe when walking; late pregnancy food intake decreased but the number of feeding increased. When the number of fetuses is small, the above-mentioned symptoms appear later or even less obvious.


(2) Abdominal palpation

Before feeding in the morning 25-30 days after mating, the owner can press the fingers together, press the palm of the hand against the abdominal wall on the outside of the uterus, and slide it along the corner of the uterus, it is possible to detect the presence of round, elastic blastocysts the size of eggs in the uterus of pregnant dogs. The number of embryos is usually arranged in a segmented line in each uterine corner, it’s easier to touch after seven weeks. During palpation, the hard feces in the rectum should be distinguished from the embryo. The feces are long and single row, deformed, and inelastic under pressure. The early maturity variety mother is young, the nutrition level is just moderate, the Huai Zai number many nests are big, one can be born early.

3. Factors that influence conception

(1) Fertilization disorders

The reason for not being fertilized can come from either the male or female dog. In the process of breeding male dogs, the main causes are poor semen quality, such as low sperm density, poor motility, high deformity rate, or low effective sperm count, etc. . In this case, the male dog cryptorchidism, false mating (there is mating action but not ejaculation) will lead to empty. Sexually active males with Oligozoospermia and Azoospermia are more at risk. A thorough investigation of the conception of a female dog with a female can be found by examining the quality of the semen.  It’s more complicated than that. Some are genetic or congenital factors such as vaginal atresia, small ovaries, oviduct Stenosis, the latter two can not be examined. Female dogs are overweight or extremely thin and have an imbalance of nutrients (such as a lack of certain amino acids, vitamins, and micronutrient), suffering from vaginitis, Endometritis, uterine effusion or pus accumulation and other reproductive tract diseases can cause non-estrus, or ovulation is not normal, reproductive tract environment is not conducive to sperm movement or even kill sperm. Oestrus identification is not accurate, late mating (late mating), is also an important cause of infertility.


(2) Embryo death

Poor nutrition, low luteinizing hormone secretion, inflammation in the uterus, strong stimulation, infectious diseases or other high-fever diseases, and poor embryo viability can cause early embryo death and the performance of “not embryo. ”.

(3) False pregnancy

There were similar changes in body shape and behavior in normal pregnant dogs, such as the enlargement of abdominal girth and the behavior of putting up litter at the 55th day of pregnancy, but they did not give birth and returned to normal. It can happen whether or not you have been mated during estrus. Hormone secretion disorder is the most important cause of the disease. There was no difference in the level of cloud one in the blood 7 weeks or more after ovulation in the pseudopregnant dogs and then it suddenly dropped to the same level as in the prenatally dogs 1-2 days. Therefore, it is extremely difficult, if not impossible, to identify any infected dogs in time, except for those that have not been bred and can be detected early on the basis of production records. The disease is extremely stubborn and prone to recurrence. Dogs with two consecutive false pregnancies should not be rebred.
