Vaginal Discharge in Dogs

Vaginal discharge refers to any substance coming from the animal's vagina. Types of discharge can include mucus, blood, or pus. Since there are so many causes for this medical condition, consulting with a veterinarian is highly recommended.

Symptoms

Symptoms can include discharge from the animal's vagina, spotting of blood, scooting the hindquarters, attracting males.

Causes

Reasons for why an animal would experience discharge include:

• Urinary tract infection
• Foreign body
• Vaginal trauma
• Abnormal cells in the vaginal area
• Fetal death
• Retained placenta following a birthing
• Vaginal infection

Some antibiotics can cause vaginal discharge. Estrogen medications given during some phases of the animal's heat or estrous cycle, medications containing male hormones, and certain antibiotics can alter the vaginal cells, leading to excess discharge.

Diagnosis

Upon examination, the veterinarian may find blood, pus, urine or feces in abnormal quantities. The veterinarian will need to review the animal's medical history and make a risk assessment. Radiograph or injection imaging may be used to examine the body for any more underlying medical conditions that would cause the vaginal discharge so that proper treatment can be prescribed.
