Hello, My GSD is 11 months old and we recently moved into a new home where there is a construction site across the street. He is so afraid of the cement trucks, the banging and overall the loud nosey area and i will include public buses. He is so afraid he will cry out jump on me and try to run back to the house. We have him on a prong collar for leash training and he is usually a very good pup. Never pulls unless there are loud noises. We have tried to correct the jumping/pulling with the collar but is doesn't seem to work he just barks and doesn't focus. He does sit and just barks or cries out. When he sits i try to give him a treat or ball but he is not interested at all. How can make him more secure and not fearful of all this construction noises? Help!
