Improvement in Coat Condition Observed in Dogs With Suspected Alopecia X Through Combined Supplementation With Nutrients for the Coat and Skin: A Case Report

A case report describes an 8-year-old Chihuahua with suspected alopecia X, characterized by significant hair loss. The dog was treated with a combination of horse placenta extract, taurine, and vitamin B complex (B1, B2, B5, and B6) as non-pharmacological therapies. After 66 days of supplementation, the dog showed marked improvement in hair coat coverage, with no adverse events reported. The supplementation was stopped after the improvement, and no hair loss was observed during a 76-week follow-up. The study suggests that combining supplements from different categories may offer a novel, non-invasive treatment option for alopecia in dogs.
