TLDR The dog likely has a condition similar to Canine alopecia X.
A 6-year-old spayed female Samoyed dog was evaluated for a 6-month history of non-pruritic alopecia on the hips and back, with hyperpigmented skin in those areas. The dog had a history of hypothyroidism and a urinary tract infection, and was on multiple medications including levothyroxine. Bloodwork and tests for Cushing's disease were negative, and skin scrapes, cytology, and cultures showed no abnormalities. Biopsies revealed hyperpigmented and alopecic areas, suggesting a condition similar to Canine alopecia X.
