TLDR Hypothyroidism-related skin issues in dogs are most common in older male Labradors, causing hair loss, slow heart rate, and obesity.
The study investigated the incidence and haemato-biochemical changes in dogs with dermatoses linked to hypothyroidism over a period from March to August 2025. Out of 720 cases, 19 dogs were suspected, and 12 were confirmed with hypothyroidism-related dermatoses, showing an overall incidence of 1.67% and a hospital-based incidence of 63.16%. The condition was most common in dogs aged 6-10 years, predominantly affecting males (75%) and Labrador Retrievers (66.67%). Key clinical signs included alopecia (91.67%), bradycardia (83.33%), and obesity (75%). Affected dogs showed significantly higher levels of TLC, neutrophils, ALT, cholesterol, and triglycerides, and lower levels of eosinophils, Free T4, and Total T4 compared to healthy dogs.
