I often receive questions from netizens: How to breed dogs? Why did my dog not get pregnant despite being bred many times?
Today, I encountered another question from a netizen: Why did the dog not get pregnant after mating twice?
I would like to summarize an article and share it with netizens who need it, and introduce some of my own experiences in judging the success of dog breeding. Everyone can refer to it.
Some information was found online. Everyone For reference only, there are some methods and they are not very uniform.
If you want your dog to get pregnant successfully, there are roughly two steps: 1. Take stock of your dog’s estrus state. 2. Choose a suitable time for breeding. 3. After breeding, do not let the dog do violent activities or be frightened. 4. Improve nutrition and provide some highly nutritious dog food.
1. Early estrus
The estrus performance of dogs can be roughly divided into two periods, namely proestrus and estrus. Proestrus is the period of time before the female dog officially begins to come into heat. At this time, the female dog's vulva will be red and swollen, and blood and mucus will flow out. This period lasts for about 7-10 days, and then enters estrus.
The vulva of a female dog in estrus continues to be red and swollen, but the blood-like secretion is obviously lighter in color. Male dogs will be extremely restless and climb astride the female dog during the estrus period, which usually lasts for 6 to 10 days. Female dogs ovulate on the 2nd to 3rd day after entering estrus, which is the best time for mating and the easiest time to conceive.

2. The mating process
The mating behavior of dogs is very different from that of ordinary domestic animals. This is mainly because the structure of the reproductive organs of male dogs is relatively special. Generally, there is no baculum in the penis of domestic animals, but there is a baculum in the penis of a male dog. It can be inserted into the vagina of a female dog without an erection during mating. After the penis is stimulated by the vagina, the glans cavernous body located at the front end of the penis bone immediately becomes congested and rapidly expands, and its circumference increases by about twice the original size. Then it is stuck and locked by the vagina of the bitch, so that the penis cannot come out. The degree of tightness makes it often difficult to separate male and female dogs.
At this time, the male dog turns around and slides down, with his back to the female dog, and forms a special tail-to-tail posture with the female dog. At this time, the male dog and the female dog look like conjoined dogs with their buttocks stuck together, mating. The time is about 10 to 45 minutes. When the male dog has finished ejaculating and the corpus cavernosum of the penis has shrunk, the penis can be prolapsed and separated.
3. Precautions after mating
Do not do it immediately after matingPulling and driving, especially male dogs, must not do strenuous exercise after mating. Generally, male dogs can be bred twice a day, preferably in the early morning or evening in hot weather, and preferably at noon in winter. After mating, they should rest for 2-3 days and strengthen Feeding.
4. Confirm the pregnancy time
About one month after mating, bring it to a veterinarian or experienced person for palpation to confirm whether the female dog is pregnant. If the dog's pregnancy period is 63 days, it may deviate, usually from 59 to 65 days. If it deviates from this number, please bring it to the doctor for diagnosis. At the same time, the greater the deviation from the expected date of delivery, the lower the chance of BB survival. .
When she was pregnant for about a month, The female dog's abdomen will begin to swell and her nipples will become larger. At the same time, the vagina will be swollen more than usual like in estrus, and fluid may flow out from time to time. The female dog will also lick her vagina frequently. In addition, the female dog will experience slight vomiting, and because the stomach is compressed by the fetus, the female dog’s appetite will be worse than usual. Therefore, it is better to eat less and more frequently, and at the same time, make the food easier to eat, such as Soak the dog food, add canned food, etc. and feed it together, and give high-protein food (convert to puppy food). You can also give cheese, eggs, calcium powder and other supplements.
After a female dog becomes pregnant, she will become more reluctant to move. However, moderate exercise, such as walking, is necessary and will help the female dog give birth in the future. However, too intense exercise should be avoided. , you should also be careful not to push the female dog's abdomen. Also, a pregnant female dog will be more aggressive than usual. Therefore, if a female dog meets a companion, she should be careful to observe to avoid fighting scenes.
If the dog fails to become pregnant for a long time, Pet Sky believes that the dog may have uterine diseases, such as uterine fibroids or uterine abscesses, etc. It is recommended to go to the hospital for a check-up, or listen to the doctor's advice suggestion.
