I do appreciate all of the training advice I've gotten. My original question of wether this is a socialization fear issue, or a problem with weak nerves still keeps me up at night. It seems to be mostly weak nerves, but I get told it's a training issue and that makes me wonder. I have another question now. I might think about returning him. The breeder does not offer any temperment guarentee (I thought they did, but I was wrong) but they will take dogs back, no refund. How would any of you bring that up to a breeder? Just looking for a good way to say it. I have brought up concerns about his fear several times, but she always said it's just me, not him. This is very hard for me to write, we love him very much, we just don't know if we can live with a dog like this. BTW, new behavior, he is resisting corrections, is that common adolescent behavior?
