In general, the lifespan of a German Shepherd is around 9 to 13 years. However, the longest a German Shepherd has ever lived in 18 years.
During the “teething stage” of the German Shepherds, their ears can become floppy. Their floppy ears usually last between 16 and 20 weeks, and by then, the cartilage in the ears will soon become hard enough to achieve its signature look – ears stand permanently.
A German Shepherd puppy weighs a little over 500 grams at birth. When they grow adults, they can reach a heavyweight of up to 90 lbs for the males and 70 lbs for the females.
