Why Your Dog’s Stomach is Turning Black
A dog’s stomach can gradually turn black due to a process called hyperpigmentation, a medical term used to describe patches of skin that become darker than other parts of the body. Here are the most common causes of hyperpigmentation.
Skin Infection and Disease
Hyperpigmentation around the dog’s stomach could be a result of a skin infection. Dogs are prone to a number of different skin infections including those that are caused by bacteria and yeast. The dark patches along the dog’s stomach may also form due to parasitic skin diseases like mange. It’s important to have your dog checked by the vet if you suspect he is affected by any of these skin diseases.
A dog’s stomach may also turn black due to an endocrine disorder. The endocrine system is responsible for producing hormones that the body requires in order to function properly. The endocrine system can be affected by conditions like Cushing’s disease and hypothyroidism. These conditions may result in an imbalance of hormone, which may contribute to hair loss and darkening patches of skin.
Some dog breeds are more prone to developing black patches along their stomach. For example, huskies and other related breeds are more likely than other dog breeds to get alopecia X, which contributes to hair loss and hyperpigmentation.
