I am thinking of getting a german shepherd dog, do i need to know anything about them that i already dont know. Would he kill me in 5 years? would he bite my girl friends hand off, would he kill someone? Does any MR members have a german shepherd and can help me out, i really want one and will take really great care of it. I have a nice huge back yard, 30,000 square feet of grass/garden where he can run about, i will walk him 3-4 miles a day or 5 times a week. The dog will have plenty to do, i have lots of friends always over, they will always play with him. The only think i am afraid of is that he will be aggressive after 3-5 years and bite someone.
