“Vaginal prolapse/hyperplasia”
•Vaginal hyperplasia and prolapse in dogs are primarily caused by estrogen stimulation during the heat cycle, genetic predisposition, and increased physical pressure.
*Hormonal Factors
•High Estrogen: Peak estrogen levels during proestrus and estrus cause normal vaginal tissue to swell, fill with fluid, and overgrow.
•Hormone Imbalance: Ovarian cysts or outside sources of estrogen can over-stimulate the vaginal walls.
*Breed and Genetics
•Young Intact Females: Most common in young dogs during their first few heat cycles.Susceptible Breeds: Boxers, Bulldogs, Mastiffs, and other large or flat-faced breeds face a higher risk.
