German Shepherds are good dogs but not a breed for everyone much as the breeds I have a St. Bernard and Anatolian Shepherd are not for everyone due to their innate and/or physical characteristics.

You are correct socialization of any dog is important as is experiencing different everyday circumstances as this helps them interpret other new experiences. When I introduce my Anatolian Shepherd to a new person, I have to sit on the ground to show him that I am comfortable in their presence while no introduction is necessary for the St. Bernard.
