Alopecia is a technical term for loss of hair or baldness. In dogs, alopecia X is characterized by progressive hair shedding and skin darkening. The condition is common among adolescent and young adult dogs. Little is known about the potential causes of black skin disease. Hormonal imbalance, obesity, allergy, and genetics are often considered as potential contributing factors.

Compared to other types of alopecia, the loss of hair in alopecia X follows a distinct pattern; the outermost hairs fall out first and the undercoat appears dry and has a cottony texture. In time, the undercoat falls out equally from both sides of the body, leaving the skin bald and dark in color. Affected dogs lose hair evenly on both the right and left side of their bodies. In extreme cases of Alopecia X, only the fur on the head and paws of affected dogs remain. Fortunately, the problem is only a cosmetic condition; affected dogs don’t suffer from pain or itching. 

Since hair loss can be an important sign of various health issues, it’s a good idea to bring your pet to your veterinarian care LaPorte, IN for a thorough checkup.
