Reproductive Diseases in Dogs

Reproductive diseases can affect any dog.

Diseases of the reproductive system in dogs usually develop from structural deformities, infections or the process of aging. Because these illnesses can lead to other health problems, pet owners should contact their veterinarian at the first sign of canine reproductive disease.

Phimosis

Phimosis is a condition in which the skin covering the dog's penis is too small. It can be a birth defect or be caused by injury. Usually, phimosis causes problems only with mating, but extreme cases can cause urinary difficulty as well. Surgery corrects the problem.

Prostate Enlargement

Older male dogs can suffer from prostate enlargement like their human counterparts. Since neutering eliminates the testosterone that fuels prostate enlargement, this usually affects only dogs that haven't been neutered. Prostate enlargement can lead to urinary problems, infections and cancer.

Pyometra

This type of uterine infection most commonly occurs in middle-aged female dogs that haven't been spayed. Pyometra begins with a hormonal imbalance after a heat cycle in which fertilization didn't occur and infection follows. Spaying removes this risk.

Vaginitis

Since a female dog's urine flows through the vagina, a urinary tract infection can cause an inflammation and infection of the vagina called vaginitis. Untreated vaginitis can lead to urinary incontinence and more widespread infection. Your veterinarian will prescribe antibiotics to quell the infection.
