Dogs are mammals that come into heat, mate, and then reproduce the next generation. In the course of a dog’s life, they are not born ready to breed, but they have to grow up and mature before they can be mated. If you want your dog to breed the next generation with high quality, you need to know their best mating time, only dogs mated at the best time to ensure the quality of the next generation. Mating time mating time, is a very critical issue, it determines the offspring dog good degree, but also determine the fertility rate is high, therefore, must be based on the bitch estrus period to project the best mating time, for the dog’s eugenics to lay a good foundation. The method of projection is to confirm that the bitch’s pubic door has obvious swelling and flushing or see the first drop of blood counted as the first day, the first mating in the first dog generally in the 11-13 days, the first mating in the 9-11 days after the dog. The first mating is moved forward 1 day for every 2 years of age or every 2 litters of litters. Some high yielding bitches give birth several times and then their vagina stops bleeding after 5 days of estrus and mating on the 6th or 7th day is the best time. There are a few bitches that do not have vaginal blood discharge in the pre-estrus and estrus period, and some bitches have blood-like discharge that can continue into the estrus period, or even into the late estrus period for several days, so the dog cannot rely on observation of vaginal bleeding to determine the mating date. At this time, the male dog can be used to test the situation. 1-3 days after the female dog is willing to accept the male dog for mating is the most suitable mating period. If the start date of vaginal bleeding is not found, the best mating date can be determined according to the color change of vaginal discharge, i.e. 2-3 days after the color of vaginal discharge changes from red to straw yellow. At this time, the labia are soft and the vaginal vestibule, which was in a vertical state, becomes flat and straight, which facilitates the insertion of the male dog’s genitals. Notes mating objects: 1. the same species and size difference is not large, but should avoid inbreeding. 2. It is best to choose a young and strong male or female dog, after the age of seven is best not to consider. 3. Healthy body without genetic diseases. Mating two dogs do not have such as epilepsy, cryptorchidism, heart disease, deafness, cataracts, dental bite incomplete, hernia, bone and joint diseases or have serious skin diseases. Such dogs are mated to have the best quality puppies. Preparation before mating: Before mating, male and female dogs should be examined for health, prevent epidemic infection, deworm the female dog, and increase nutrition appropriately. The male dog before mating should not be fed too much, nor should the male dog be allowed to proceed on an empty stomach. Too full will occur reflex vomiting, too hungry will have an impact on the male dog and mating. Mating should be done at the time when the male and female dogs are in the best mental state, preferably in the early morning. The best place for mating is in the place where the female dog is kept or in a quiet place to minimize the presence of people to prevent them from being disturbed during the mating process. Before mating, the dog should be allowed to roam freely and excrete urine and feces. Mating times: Generally mating 2 times, after the first mating, 1-2 days between the second mating. Can use the “double mating” (i.e., 2 males and 1 female) mating method, the first time to choose a male dog mating, interval of 1 day and then another male dog mating 1 time. Another method is “repeated mating”, that is, after choosing a male dog to mate, and then mating with the same male dog 1 time after an interval of 1 day. The female dog ovulates several times during the sexual excitement period, and “double mating” or “repeat mating” can increase the chance of fertilization of the egg cells and increase the number of fertilized eggs, thus improving the fertility and litter rate. The number of times a male dog is mated should be noted, the argument that the number of mating is good for conception and good litter is not true. Generally speaking, the number of times a male dog should mate is one per day. Mating steps: On the day of mating, bring the bitch to the male, as most bitches are very territorial. If the male dog goes to the female, this requires a very strong self-confidence in the male dog. If possible, let the two dogs socialize first to “get to know each other” before actually mating. If the female is not used to being around other dogs, she may refuse to mate. Breeds with hostile natures may be more difficult to mate. It is usually important to hold the bitch tightly during the mating process to prevent her from doing any hostile harm to the valuable male. First when the bitch is ready to mate, she will set her tail out to the side. The male dog rides on the bitch’s back and initial ejaculation occurs. A portion of the male dog’s penis (the head of the pubic neck) swells up and into position so that they are attached to each other. Next, after about 1 minute, the male dog gets down and turns around to stand back-to-back with the female dog, still attached. This position usually continues for 20 minutes and then ends naturally. Although this phase does not require supervision, some caution must be exercised. The bitch may suddenly become aggressive or may twist too hard too soon and injure the male, and again, never force the two dogs apart. Mating methods: Mating methods for dogs are natural mating, assisted mating, forced mating and artificial insemination, which method should be used depending on the specific circumstances of the male and female dogs to determine: 1. Natural mating: suitable for male and female dogs of similar size, male and female dogs have mating experience, female dogs in heat performance is obvious, the female dog can remain standing stable when the male dog climbing across the situation. Before mating, choose a secluded, unobserved place with flat but not smooth ground, scatter the male and female dogs among them and wait for their natural mating. 2. Assisted mating: It is suitable for male and female dogs without mating experience or for male and female dogs with uncoordinated body size, and for female dogs that do not cooperate when the male dog climbs across. When mating, the owner holds the bitch’s collar, then holds her chest and abdomen with the other hand (small dogs), or bends the knee to support the bitch’s chest and abdomen (large dogs), so that she maintains a stable standing position. To prevent the bitch from squatting while the male dog is climbing across. 3. Forced mating: Applicable to the female dog although in heat but has a refusal to mate vicious, or male and female dog size difference and other situations. The method of forced mating is similar to assisted mating, but the female dog should wear a muzzle to prevent her from being forced to turn around and bite a person or male dog. The male dog used for forced mating must be sexually active and have experience in mating. 4. Artificial insemination: general family dog does not use this method. This method requires certain equipment and techniques and is mainly used in large-scale breeding farms. Note that breeding male dogs and pregnant and lactating female dogs need to supplement a large amount of calcium, because semen, embryonic dogs and milk can lead to a large loss of calcium from the body, and if they are not replenished in time, they will use the calcium in the body’s calcium stores and cause osteoporosis.
