A 6-year-old male, blue Doberman pinscher crossbreed was presented with coat abnormalities; in particular, flank alopecia and pruritus. Based on medical the history, clinical evidence, and histopathological examination, color dilution alopecia was diagnosed. The dog was with oral melatonin treated for 3 months without success.

Alopécie à dilution de couleur chez une race croisée de Doberman Pinscher bleu. Un Doberman Pinscher âgé de 6 ans est présenté avec des anomalies du pelage; en particulier, une alopécie du flanc et du prurit. En fonction de l’anamnèse, des signes cliniques et de l’examen histopathologique, l’alopécie à dilution de couleur a été diagnostiquée. Le chien a été traité sans succès à la mélatonine pendant 3 mois.
