Abstract

Years ago, dogs were not considered part of the family and little attention was given to them, but over time these animals have formed a fundamental part of the family, therefore, living conditions and animal welfare have improved. . The estrous cycle of the canine happens every 6 months. Sterilization is a surgical technique that can be performed medially or laterally and helps females to prevent unwanted pregnancy, diseases of the reproductive system, hormonal, prevents the use of progestogen-based contraceptive injections that alter the normal hormonal level of the bitch This surgery should be performed when the bitch has a well-formed genitourinary system, it depends a lot on the type of breed. Of the hormonal diseases or pathologies we have mammary tumors, these neoplasms occur exclusively in older or geriatric and adult bitches, which are not sterilized and have shown hormonal alterations throughout their lives, presenting pseudopregnancies or psychological pregnancies, coming to manifest in the mammary glands where the lymph nodes are involved, and this cancer can spread, appearing as metastasis and causing the death of the animal. The hormones involved in the growth of this are estrogens, progesterones, prolactin, the insulin factor, among others. There are two types of tumors that are benign and malignant, and studies have shown that the neoplasms that are more frequent are malignant than benign.
