Babies are starting to get ready. Recently, many novice parents are at a loss for their baby's pregnancy and are at a loss. Please accept this guide to pregnancy for dogs and cats.
Pregnancy physical examination is a method to allow pregnant animals to receive scientific guidance from doctors through systematic prenatal examinations, ensuring the physical and mental health of pregnant animals and the healthy development of the fetus.
1. The pregnancy period of dogs has a large variable, ranging from 57 days to 72 days. Why is it so long? The main reason is that the dog's sperm enters the uterus and can live for 6 to 11 days, so it is assumed that it is 11 days. Now, after breeding, the eggs of the bitch are arranged within 10 days, which means that it will be fertilized after 10 days. So pregnancy is 10 days, and the pregnancy period may run to 70 days. This is why the dog has a 57-72-day variable during pregnancy, and the main difference is in this place. The pregnancy period of dogs is generally 58-63 days.
The pregnancy period of cats is ovulated only after they are bred, so the pregnancy period is relatively consistent. The pregnancy period of a cat is generally 63-66 days. What are the clinical manifestations of

1. After pregnancy, animals may gradually decrease exercise, gradually increase abdominal circumference, and gradually increase weight, especially in the later stages (after 40 days of pregnancy), the appearance will be more obvious.
2. The breasts begin to swell two weeks before delivery, and colostrum appears a few days before delivery.
3. 1-2 days before delivery, animals start to build nests and feel uneasy. They look for secluded and dark places, use slashing ground, biting objects, and urinating more frequently, especially in primary animals.
4. The body temperature begins to drop to between 36.5 degrees and 37.5 degrees 3 days before delivery. When the body temperature begins to rise, it means that the delivery is about to occur.
What are the inspection methods? What can

B-ultrasound do?
Confirm pregnancy: The gestational sac appears, forming a small thin walled non-echo structure in the uterus, and fluctuating fetal heart can be seen; dogs can be identified in 23-25D, and cats can generally be identified in 16-18D.
Detection of fetal development: The fetus develops more rapidly after 30D, so that internal organs can be more easily identified. Measure the approximate pregnancy date and delivery time according to the size of the fetus; the pregnancy date will have 3-5D errors due to the breed size and development;
determine abnormal pregnancy: including embryonic absorption and miscarriage, manifested as the disappearance of the gestational sac, increase in intraluminal echoes, disappearance of the fetal heart, and embryo or fetal dissolution.
Assess the fetal vitality: The normal fetal heart rate is twice the maternal heart rate. Hyper-heart rate is the normal response of the fetus to hypoxia and is also an important parameter for diagnosing difficult labor.

2. The most common clinical method of X-ray diagnosis is X-ray diagnosis, because this method can not only diagnose whether animals are pregnant and the number of fetuses, but also distinguish them from the pseudo-pregnancy that occurs in clinical practice.
When a dog is pregnant, it will only see the size of the uterus and the density of soft tissue. It will only be possible to see the fetal bones after 41 to 45 days. If a cat is pregnant, you will only see the fetal bones after 35 to 39 days.
Wait until the dog is 41~45 days and the cat is 35~39 days, the fetus's bones begin to calcify. At this time, taking an X-ray can determine whether the pregnancy is present and the specific number of the fetus.
Postpartum uterus rehabilitation
The uterus after delivery contains an inequality of fluid, and gradually returns to normal size 4-6 weeks after delivery (the cat's rehabilitation time may be shorter), and lochia stops discharged. If abnormal secretions still exist six weeks after delivery, it should be suspected that the uterus rehabilitation is incomplete.
