Pituitary dwarfism is a metabolic disorder that affects German shepherds, Saarloos Wolfdogs and Czechoslovakian Wolfdogs. Pituitary dwarfism is characterized by a combined deficiency of growth hormone, thyroid-stimulating hormone (TSH), prolactin, and gonadotropins. The hormone deficiencies can lead to a wide range of clinical manifestations, but the most common ones are marked growth retardation, retention of lanugo or secondary hairs with concurrent lack of primary or guard hairs, and bilateral symmetrical alopecia.
