Do dogs do menstruation like humans? Obviously mammals and humans have similar reproductive organs, but their function is not the same. Human women experience a cycle called menstrual cycle every month. Women's menstruation occurs when the ovaries in the ovaries become ovulated. It is a process to meet and correct sperm.
Dogs have a cycle of estrus. There is a case where a dog that grows a female dog sees the bleeding of a dog and makes dogs menstruation. For men, women's menstruation is the process by which blood is released through the vagina when the endometrium is removed when the fetus does not enter the uterus, which prepares for pregnancy.
On the other hand, in the case of dogs, if the egg fails to be fertilized, it will not be released out of the body. In other words, the blood shed by female dogs is not from the uterus but from the vagina. For human women, menstruation is the end of the menstrual cycle, but for dogs the horn is a signal to signal the beginning of fertility.
The estrus cycle of dogs
Dogs do not have a menstrual cycle, so asking whether they actually have menstruation is a question from a very human point of view. The dog's estrus cycle consists of four stages: ▲ estrus cycle ▲ estrus cycle □ estrus cycle → non-estrus cycle.
During estrus and estrus, female dogs secrete blood and body fluids through the vagina. More blood is shed on the estrus rather than the estrus. The meaning of a commonly spoken dog is that it means a dog that has entered the estrus or estrus period.
During the estrus cycle, a significant amount of estrogen is secreted from female dogs, and the effect of this hormone lasts for about 17 days. During this time, too much hormone and pheromone is secreted, so the blood is shed in the aftermath. Dogs undergoing estrus or estrus often see urine more often than usual, because the hormones and pheromones in the blood and urine spread far enough to attract male dogs.
During the estrus cycle, the estrus is the shortest period of 4 to 7 days. During this cigar, the dog recognizes the estrus and finds a partner for mating. Hemorrhage continues even during the estrus period, but the frequency is lower than that of the estrus, and the color of the blood is also slightly reduced.
Bleeding during the estrus period is more diluted than the estrus, and pink or pale red. During this time, the dog appears to be a little less active, sleeping more, and trying to find a safe birth room for pregnancy.
When the next phase of estrus is started, the bleeding stops regardless of whether or not correction is made. The pause lasts for about 65 days, or about 3 months. This is consistent with the duration of the dog's pregnancy. If the egg is not fertilized, the nutrients in the uterus that have been prepared for the fetus are again absorbed into the mother during this estrous cycle.
The last step of the estrus is the non-estrus period, when the dog enters the pauses completely with hormones or sexually. This period lasts about 2 ~ 3 months.
Will the dog undergo menopause?
Since the dog 's estrus cycle lasts for several months, dogs experience about two estrus cycles per year. Dogs can get pregnant as early as 6 months, at least as early as 24 months.
The term or pattern of the estrus cycle depends on the type of dog, body size, and so on. Small dogs experience three cycles of estrus per year. Large dogs, on the other hand, undergo estrus cycle once a year.
Unlike humans, however, dogs do not suffer from menopause. Dogs are still able to get pregnant and give birth even if they are old, which is the difference between humans and dogs.
Dog Neutralization, Why Is It Not Essential to Choose
Before reaching the conclusion, there is one fact that dog owners must know. Some people believe that dogs have to live long enough to get rid of the ridges before they become neutralized, but this is not true. Thanks to the development of veterinary science these days, puppies can be neutralized after 6 to 8 weeks of age.
Neutralization prevents breast, uterine, and ovarian cancer. It can also protect dogs from the risk of fatal bacterial infections in dogs.
