These dogs were examined clinically and 325 dogs had one or more skin related problems. 43 dogs suspected for hypothyroidism on the basis of clinical signs, lesions, age, and excess body weight were selected for the study also included four dogs having body weight improper to their age and three female dogs having problem like anoestrus and abortion. In addition, ten blood samples from dogs suspected of hypothyroidism were collected from private Pet Hospitals, Faridabad and Gurgaon. Quantitative measurement of tri-iodothyronine (T3), thyroxine (T4) and thyroid stimulating hormone (TSH) in the serum of each blood samples of a dog was done by electrochemiluminescence immunoassay (ECLIA) using COBAS-E immunoassay analyzer. On the basis of low levels of T3, T4 and higher levels of TSH, a total of 8 dogs were diagnosed with hypothyroidism. All these eight dogs had T3, T4 levels less than the normal range of 48.00–154.00 ng/dl and 1.50–3.60 μg/dl respectively and the level of TSH was greater than the normal range of 0.30–0.60 ng/ml in all these hypothyroid dogs.
