Abstract:
Hypothyroidism is the clinical syndrome caused by reduced circulating concentrations of the active thyroid hormones T3 and T4. It is widely acknowledged as one of the most common endocrine diseases affecting dogs. The present study was carried out to know the haematological changes in hypothyroidism positive dogs. The dogs presented to the Teaching Veterinary Clinical Complex, College of Veterinary Science & AH, Durg, private clinics and government Veterinary hospitals of Durg-Bhillai, Raipur and Rajnandgaon districts of Chhattisgarh for a period of two years from March 2018 to February 2020 were included for the present study. Blood samples were collected from dogs suspected for hypothyroidism and subjected for the estimation of thyroid hormones (tT3, tT4 and fT4) and haematology. Thyroid hormones estimation showed a significant decrease of tT3, tT4 and fT4 levels in hypothyroidism dogs as compared to healthy control group. Haematological study depicted a non-significant decrease in haemoglobin, packed cell volume, total erythrocyte count in hypothyroid dogs as compared to the healthy control dogs. Hypothyroid dogs had a significant (P˂0.05) increase (p≤0.05) in total leucocyte count and neutrophils, with a non-significant difference (p≤0.05) in lymphocytes, eosinophils and monocytes between hypothyroid and healthy dogs.
