Understanding Hyperpigmentation in Dogs
When it comes to understanding hyperpigmentation in dogs, it’s important to recognize that it is not a disease itself but rather a reaction commonly associated with chronic inflammation due to an underlying medical condition (PetMD). Hyperpigmentation refers to the darkening and thickening of a dog’s skin, resulting in the appearance of black spots, splotches, or patches.
Causes and Triggers
Hyperpigmentation in dogs can be triggered by various factors, including obesity, hormonal abnormalities, allergies, contact dermatitis, skin infections, systemic lupus erythematosus (lupus), and demodicosis (parasitic skin mites) (PetMD). Specific breeds may be more prone to developing certain underlying conditions that can lead to hyperpigmentation. For example, Dachshunds are known to experience primary hyperpigmentation, which is not caused by an underlying medical condition and is breed-specific (PetMD).
Types of Hyperpigmentation
Hyperpigmentation in dogs can be classified into two main types: primary hyperpigmentation and secondary hyperpigmentation.
Primary Hyperpigmentation in Dogs
Primary hyperpigmentation is a rare form of hyperpigmentation that occurs in specific breeds, such as Dachshunds. It is not associated with an underlying medical condition and typically manifests before a dog reaches one year of age (PetMD). The exact cause of primary hyperpigmentation is not yet fully understood, but it is believed to have a genetic component.
Secondary Hyperpigmentation in Dogs
Secondary hyperpigmentation is the more common form of hyperpigmentation in dogs and is often a result of inflammation or friction against the skin. It can occur in dogs of any breed, with certain breeds being more susceptible due to their predisposition to specific underlying conditions.
