Acanthosis Nigricans(AN)
Also known as: Primary Acanthosis Nigricans · Schwarzwucherhaut · Hyperpigmentation of the Axillae · Canine Acanthosis Nigricans · Schwarze Acanthose · …
Overview
What it is
Acanthosis Nigricans is a chronic skin disorder where the body produces excess pigment and skin cells, leading to dark, thickened patches of skin, especially in the armpits and folds. In dogs, particularly Dachshunds, this is often a genetically predisposed condition where the skin's normal shedding and pigment processes are disrupted. This thickening and darkening can eventually cause hair loss in the affected areas.
How it presents
Owners typically notice dark, leathery patches of skin in the dog's armpits starting between 3 and 12 months of age. Over time, these patches can spread and may be accompanied by intense itching, a noticeable odor, and secondary skin infections.
Treatment
While the primary genetic form is incurable, it can be successfully managed throughout the dog's life with medicated shampoos and anti-inflammatory treatments. This lifelong management typically costs between 1,500 and 5,000 EUR.
