'Crude animal-origin thyroid preparations are not recommended for the treatment of hypothyroidism in dogs. Nevertheless, these preparations have been used successfully. The recommended dosage is 15-20 mg of dessiccated thyroid per kg of body weight once daily (Rosychuk, 1982). Ideally the tablet should be crushed and administered with a small amount of food.'
