Here are a few common reasons that may explain female dogs that have black colors appearing in their vaginal area.

1. Buildup of dirt and debris

Is it the fur along the dog’s vaginal area that is turning black? In such cases, it might just be a case of accumulating dirt. Your dog might have a habit of rubbing or scooting his butt along the floor and that’s making the vaginal hair dirty and black. It could also be stains from the dog’s poop and urine. If this happens frequently, there might need to be an investigation into the underlying health issue that’s leading to the black vaginal hair.

2. Vaginal skin is necrotic

The skin tissues around the dog’s vulva could be dying off due to a serious infection. There are many types of skin infections that could affect the dog’s vagina, including vaginitis, yeast infection, and staph infection. Please have the dog checked with the vet as soon as possible so that the underlying health problem can be properly diagnosed.

3. Chronic urinary issues

Chronic issues like urinary incontinence may lead to the darkening of the dog’s vaginal area. For example, the constant leaking of urine may cause urine burns, a painful rash that develops when the dog’s skin comes into contact with urine for a long period of time. This, in turn, may lead to dead skin tissues, especially if the urine is coming into contact with the dog’s vaginal area.

The presence of black or dark skin pigments around the dog’s vulva could a be a sign of a serious underlying health condition. Call the vet and have your dog go through an examination.
