Pattern baldness
Also known as: Canine pattern alopecia · Pattern alopecia · Muster-Alopezie · Symmetrischer Haarausfall · Acquired pattern alopecia
Overview
What it is
Pattern baldness is a cosmetic, genetically influenced condition affecting the skin and coat. It occurs when hair follicles gradually shrink over time, leading to localized hair loss. Because there is no underlying inflammation or infection, the skin itself remains healthy and unaffected.
How it presents
Owners typically notice gradual, symmetrical hair thinning or baldness starting within the first year of life, most commonly on the ears, neck, chest, or thighs. The affected areas do not itch, crust, or cause the dog any discomfort.
Treatment
This is a purely cosmetic condition that does not require medical treatment, though melatonin is sometimes used to support hair regrowth. If supportive therapies or diagnostic vet visits are pursued, lifetime costs generally range from 100 to 500 EUR.
