Zinc-responsive dermatosis in dogs: 41 cases and literature review


Dr. Stephen D. White, Department of Medicine and Epidemiology, School of Veterinary Medicine, University of California, Davis, California 95616, USA.


Forty-one cases of zinc-responsive dermatosis in the dog are described. The Siberian husky was the predominant breed affected. Periocular crusts were the most common clinical sign and parakeratosis was noted in the skin biopsy specimens of all dogs. Treatment with oral zinc ameliorated the clinical signs in most dogs, but cases necessitating other treatments such as parenteral zinc or retinoids are reported. The authors recommend a starting dose of 2–3 mg kg−1 elemental zinc per day in the treatment of this disorder.
