Some shed less and some shed more. Females blow coat twice a year. My worst shedder was a tight, short coated male -- he shed constantly. Of course he was my first, and his dog food wasn't the greatest.
On the whole, if you are concerned about hair, the German Shepherd is not the right breed for you.
On the other hand, grooming your dog is great bonding, and if you brush your dog once a day, and get them groomed as soon as they start blowing coat, you will cut down shedding a lot. People who love the breed look at a little hair as a small price to pay for a wonderful addition to the family and home.
