The estrus period of dogs is generally more obvious in female dogs. The estrus period will be irritable, make turbid courtship barking, lose appetite, swelling of the vagina, and frequent urination. The most prominent feature is that there is bloody mucus in the vagina. The labia begins to swell around about a week after estrus, and the amount of bleeding decreases. If you touch your hand near your hips, the bitch will bend your tail to one side, indicating that you are starting to mate.
2. Pregnancy period
(1) Characteristics: Generally, the pregnancy period of a bitch is about 63 days. About twenty days after the bitch mates, she will have no appetite, vomiting and other symptoms. The appetite then returns to normal and the breasts gradually enlarge. Experienced breeders can use their hands to feel the number of fetals around the fourth week.
(2) Nursing: During pregnancy, the bitch's appetite is much larger than usual, and the abdomen will grow rapidly. At this time, you must pay attention to giving foods with higher nutritional properties, and some nutritional products such as calcium powder and cod liver oil can be added to the food. At the same time, the female dog should be allowed to exercise enough and often bask in the sun to promote the development of fetal bones. Ensure that the female dog has good physical strength so that it will not cause difficult labor due to weak physical strength during childbirth. As the fetus grows, the bitch's stomach and intestines will be compressed by the uterus, so it is necessary to eat less and eat more, and you can feed it 5 to 6 times a day. In the later stage of pregnancy, do not let the bitch do intense exercise, especially beating and climbing, and try to avoid it. At the same time, you should also stop bathing.
