Plasma triiodothyronine (T3) and thyroxine (T4) values were determined before and after thyroid stimulating hormone administration in 25 dogs with pyoderma and in 15 controls. Basal T4 values were increased in dogs with pyoderma, but the stimulated T4 and T3 values were not altered by this condition. On the basis of low values for circulating iodothyronines, hypothyroidism was suspected in three dogs with pyoderma. The dog with the most involved lesions had extremely low T3 and T4 values as well as an autoimmune disease. It is concluded that most dogs with pyoderma do not have thyroid dysfunction.
