Alopecia in Dogs: Causes, Incidence, and Clinical Signs with Special Reference to Nutritional Alopecia

This study, conducted from July 2019 to June 2021, evaluated 2,225 canine cases and found that 485 (21.7%) exhibited alopecia, with mange being the most common cause, followed by flea and tick infestations. Nutritional alopecia, primarily due to deficiencies in copper and zinc, was also noted. Alopecia was more prevalent in males (59.7%) and dogs under one year of age (36.3%). Seasonal variation showed higher incidences in summer (38.8%) and spring (30.3%). Dogs with nutritional alopecia had significantly lower levels of hemoglobin, packed cell volume, RBCs, WBCs, copper, iron, and zinc compared to healthy controls. The study emphasizes the importance of regular grooming, a clean environment, and proper nutrition to manage and prevent skin disorders in dogs.
