Overview
Ovarian cysts in female dogs include follicular and corpus luteum cysts. Follicular cysts are caused by unbroken follicles, resulting in increased folliculin and high estrogen content, requiring luteinizing hormone treatment; When a luteal cyst occurs, luteinizing hormone increases, so that the content of progesterone increases, causing the female dog not to estrus.
Causes of Ovarian Cysts In Dogs
Follicular cysts are caused by excessive follicle-stimulating hormone secreted by the anterior pituitary gland and insufficient luteinizing hormone, so that the follicles grow excessively and cannot normally ovulate and form the corpus luteum, or because the ovaries continue to produce new follicles. After luteinization of the cells on the wall of the follicle, the cells of the corpus luteum undergo degeneration, forming the corpus luteum cyst.
Symptoms of Ovarian Cysts In Dogs
Chronic symmetrical depilation on the back of the trunk, thickening of the skin, and hyperpigmentation of the skin are common in bitches with ovarian cysts. When the follicle cyst, the female dog continued estrus, hypersexuality, vultia swelling, sometimes bloody secretions, often crawling across other dogs, toys or people's trouser legs, etc., but the female dog refused to mate; Females with corpus luteum cysts are not in estrus during this period and also refuse to mate with males.
Diagnostic criteria for Ovarian Cysts In Dogs
Clinically, preliminary diagnosis is generally made based on symptoms, and exploratory laparotomy can be performed if necessary.
Ovarian Cysts In Dogs Treatment
Female dogs with follicular cysts can be injected with 20 ~ 50/ug luteinizing hormone by intramuscular injection, and after 1 week, it does not respond to the injection again, and a slightly larger dose, or injected with 50 ~ 100ug of human chorionic gonadotropin by intramuscular injection. For female dogs with luteal cysts, 20 to 50U of follicle stimulating hormone (FSH) or 1 to 2mg of ethylstilbestrol can be injected intramuscuarly once a day for 2 to 3 days. Surgical removal of the ovaries can be performed if hormone therapy does not respond.
