1 Girl and her Dog-

My black shepherd is very similar in nature, although he was not hurt. He is protective, would growl and "go for people". In just 4 weeks he has improved alot. You need someone who can hold him STRONG, in fact muzzle him, and take him for walks were people are i.e shopping centres or parks. Each time he growls yell "NO" in a harsh voice, and I mean EACH time, and tug her collar. Your dog needs to know you mean it. I found this worked, and I am still working on it.Your dog should be able to overcome this issue. You also need to be strong and not let people's comments and looks get to you. Be strong and confident and your dog will pick up on this. A word of inspiration, a trainer told me I should consider putting my dog down, just 4 weeks after that comment and my hard work, I can walk him at a busy beach with no troubles. He is still alert, but allows people to walk by now. So dont give up!!!!!!!!!!!!!!!!!!! (but of course, balance this with people's safety)
