Female dog infertility refers to a pathological state in which the female dog cannot become estrus and fertilize after maturity, or even after delivery, and still cannot become pregnant even after several matings. The causes of infertility are extremely complex:

2. Malnutrition. Common dog foods include monotonous, inferior or lack of essential amino acids, minerals and vitamins, etc.
Specifically: a) and vitamin A deficiency can cause degeneration of epithelial cells, egg cells and follicle epithelial cells in the endometrium. Follicles are atresia or form cysts; vitamin E deficiency can cause pregnancy interruption, stillbirth or hidden miscarriage (fetal is absorbed); b) B vitamin deficiency can weaken the uterine contraction function, destroy the production and ovulation of egg cells, making the female animal not in estrus for a long time; c) vitamin D deficiency can cause metabolic disorders of minerals (especially calcium and phosphorus) in the body, which can indirectly cause infertility.
3. Sexual organ development abnormally. For example: reaching the age of mating, but having incomplete development of the reproductive organs or lack of reproductive ability (naive disease); sexual malformation, that is, having both male and female gonads; abnormal genital tracts, such as the slender cervix and uterine horns, the vagina or vagina is too narrow or atresia (cannot mate), etc.
4. Disease infertility. Such as cystic endometrial hyperplasia uterine purulent syndrome, uterine inflammation, vaginitis, ovarian cysts, ovarian tumors, uterine and vaginal tumors, brucellosis, toxoplasmosis, leptospirosis, etc.
5. Reproductive technical infertility. Mainly, it is poor artificial insemination technology and improper semen treatment.
