Disease
Dwarfism is a condition of abnormally small stature with additionally altered proportions in some body parts. Pituitary dwarfism in German shepherds produces perfectly proportioned but miniaturized dogs. It is caused by a gen defect, which leads to dysfunction of the pituitary gland. As a result, lower amounts of growth hormones and Thyroxine reach the blood. Hence, affected dogs stop to grow between week three to eight of their live. These dogs posses fox-like appearance characterized by set apart ears, pointed muzzle and slight over-bite. Sometimes, they twinkle more in bright sunlight then dogs from the same litter. Untreated, dogs retain their puppy-fluff or completely loose their hair, with the exception of the feed and head region. In this case, they look much like Chinese crested dogs. Also, altered hormon-composition often leads to un- or malformed genitals. When treated with growth hormones and Thyroxine, dogs can live a normal live.
