Studysummary This study reports that dogs with dermatoses linked to hypothyroidism displayed a significant incidence of specific haematological and biochemical alterations, such as elevated cholesterol and triglyceride levels and reduced thyroid hormones, compared to healthy dogs, with Labrador Retrievers showing the highest breed predisposition. Our plain-language summary of this paper — not a Tressless recommendation.
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.
