Canine Alopecia Areata: A Retrospective Study of Clinical, Histopathological Features and Treatments in 14 Dogs

This retrospective study examined 14 dogs diagnosed with alopecia areata (AA), focusing on clinical and histopathological features and treatment outcomes. The study found that 71% of anagen hair bulbs were affected, with lymphocytes present in all dogs. Oral ciclosporin was the most common treatment, leading to partial hair regrowth in six dogs and complete regrowth in two, although relapse occurred in four dogs when the medication was reduced or stopped. Oral oclacitinib was effective in two dogs, resulting in partial and complete regrowth after 3 and 5 months, respectively. Spontaneous remission occurred in two dogs. The study concludes that canine AA is a chronic, relapsing condition that often requires long-term management.
