I agree with Carie 100%! This really is important and must be addressed right away to avoid alot more heartache or even lawsuits! GSD's are very strong and capable of much damage, they might even be able to kill a young child or an elderly person with little effort. You may not want to think about costly training, but it's a whole lot cheaper then what could happen if your dog goes after the wrong person! People are so "sue crazy" now. Please listen to the advise and get your dog a professional. Don't risk it, don't risk your dog getting lose and mauling someone. It will get worse as your dog matures, Carrie is SO right about that! If the professionals are unable to help, and the dog gets more aggressive and dangerous, you may want to think about whether or not the dog is too much a threat to society to even be around. I know it's not an easy problem but to think of what it could do if the problem does not get solved is scary. I would be afraid to have that type of dog near me or my family for our own safety. Just try to keep the well being of other people in your mind as your dog matures into a strong, powerful adult.

The right professional trainer may teach you and the dog how to control this agression issue, but if not, for the sake of other people, please try to use your best judgement as to whether or not your dog is safe to be in society.
