Samoyed dog (detail introduction)
Animals have the instinct of breeding offspring. Due to the physical fitness of each animal, a series of situations are different. What factors will affect the normal estrus of the dog?
One. Season:
Dogs have the characteristics of seasonal reproduction. Under normal circumstances, the bitch is in estrus twice a year, about 6 months at a time. Most of the dog -raising dogs are in estrus in the spring and autumn seasons (March -May, September -November); group -raising dogs have estrus in all stages of the four seasons, and the seasonality is not obvious. In addition, wild dogs and Arctic circles in South America are not obvious. The breeding dogs are also estrus once a year, and the seasonality is not obvious.
2. Age:
Due to the increase in age, the physical metabolic function of the old dogs decreases, the estrus cycle is disordered, and the estrus period is often prolonged, and the estrus and estrus are shortened.
3. Early love period:
Generally, the small dog with a small body is earlier. The late love period is at the age of August to October. The dogs of the first love have a long period of estrus and estrus. In addition, nutritional and environmental temperatures also affect the initial conditions. The high level of nutritional levels is lower and early, and the tropical is cold or temperate early.
4. Nutrition:
Due to the lack of nutrition or excess (obesity), it will also extend the estrus period or cause abnormal estrus.
5. Diseases:
Due to reproductive organ diseases such as ovarian tumors and uterine pus often lead to a long period of estrus or not in estrus. In addition, when the upper nest is too much, and the nests of the nest are the same, the female dog's body fails to be adjusted and recovered well, which will also lead to a long period of estrus.
Generally, old dogs are advised not to breed her anymore, and there are risks for older women to produce. For the first time, it is not appropriate to breed, because the development of each puppy's organs is not yet mature, and the bones are still growing. Dogs of gynecological diseases are recommended to do sterilization.
