# Reproductive Problems in Dogs That Can Turn Serious Fast
Reproductive health issues in dogs demand immediate veterinary attention. These conditions progress rapidly and pose serious risks to your dog's life if left untreated.
Pyometra stands as one of the most dangerous reproductive emergencies in dogs. This infection of the uterus develops in unspayed female dogs, typically within weeks of heat cycles. The uterus fills with pus, and bacteria release toxins that cause systemic illness. Symptoms include excessive thirst, frequent urination, vaginal discharge, lethargy, loss of appetite, and fever. Without emergency surgery to remove the uterus and ovaries, pyometra kills dogs within days.
Testicular tumors occur in intact male dogs, particularly in older animals. These growths spread to lymph nodes and other organs. Early signs include swelling or hardness in the testicles, changes in behavior, and difficulty walking. Neutering removes the affected testicles and prevents metastasis.
Prostatitis, an inflammation of the prostate gland, affects older intact males. Symptoms include painful urination, difficulty defecating, blood in urine or semen, and abdominal pain. Bacterial infections cause this condition, requiring antibiotics and sometimes surgical intervention.
Ovarian cysts in female dogs trigger excessive bleeding during heat cycles and hormonal imbalances. These cysts can twist and rupture, causing internal bleeding and shock.
Mastitis, inflammation of mammary tissue, occurs in nursing dogs and non-breeding females alike. Infected mammary glands become swollen, painful, and hot to the touch. Pus or bloody discharge may leak from nipples. Untreated mastitis leads to sepsis and organ failure.
