TLDR A dog with complete hair loss regrew most hair after treatment, with no relapse after stopping treatment.
Alopecia areata universalis (AAU) in a 9-year-old male cross-breed hunting dog was documented, marking the first known case in canines. The dog exhibited complete noninflammatory hair loss for 12-14 months. Diagnosis was confirmed through clinical, histopathological, and immunohistochemical examinations. Treatment with oral ciclosporin led to significant hair regrowth, although some areas like the muzzle, eyelashes, and whiskers remained hairless after 17 months. After 5 months without treatment, the alopecia did not relapse, suggesting possible spontaneous resolution.
