Hi Pammy. I am sorry to hear of your pup being nervous, love him. It must be so awful for him. I have always owned GSDs and they have always been very confident and self assured outgoing dogs who loved people and other dogs and being fussed.
However my girlie who is nearly 12 months was quite nervous with children for a short while. She was 17 weeks old when I bought her. The first time we encountered a child and they approached her she ran behind me and was quite scared. I called her breeder and asked if she had encountered any bad experiences with children and apparently a child had spooked her when she was younger.
I overcame her nervousness by carrying treats with me and when encountering my neighbours children, I explained she was only a baby and that she was scared and that they mustnt approach her or try to smooth her. I would stand a little distance away and talk to them, at the same time fussing my pup and telling her good girl, all the time watching her body language and if she was looking at bit nervous, I would tell her "its ok". After a short time, she would be inquisitive and want to have a sniff. At this point then, I would give my neighbours children some treats for her to hold out in the palm of her hand and my pup would feel confident enough to take the treats. Repeating this on each encounter showed my pup there was nothing to be scared of. It only took a short time. But it is important that you let your dog do it in their own time and that you dont push them into stressful encounters as it could prompt a fight or flight situation.
Perhaps you could do something similiar with people you meet. Stand a distance away, far enough for him to feel comfortable so he doesnt need to try to run. Try to have him sat by the side of you and give him fusses whilst you are chatting, at the same time telling him its ok. Make sure the person you chat to doesnt look him in the eye as he could feel a bit intimidated. After a while he should start to be a little curious and once he gets to this stageand he has started sniffing the person, a treat could be offered in the palm of their hand. Something really tasty that he loves.
Dogs also feed off on on our energy as well mind. So if you start to worry or feel tense then this will feed to your dog through the lead, so its important to always remain relaxed and confident.
GSDs do go through different stages when they are puppies as they are growing and they can go through various stages where they are not as confident and its important to be consistent with them, providing as much socialisation as you possibly can and rewarding them when they have been good so its a positive reinforcement.
GSDs are wonderful dogs and like you have said pammy, they do have extremely loving personalities and with a little time and training, your boy should be ok as my girlie now nearly 12 months was fine after a short space of time of positive training.
Good luck, and let us know how you get on.
