title: Seasonal leukotrichia in a German shepherd dog. A case report.
abstract: Leukotrichia can be caused by a variety of metabolic and inflammatory diseases. Canine alopecia areata is a rare multifactorial benign non-scarring alopecia. This case report describes a seasonally recurrent leukotrichia associated with alopecia areata in a German shepherd dog. Important differential diagnoses were ruled out and histopathology finally confirmed the diagnosis of alopecia areata. Topical tacrolimus and hydrocortisone aceponate were ineffective. The cause for the seasonal character in this case remained undetermined.
