aww well maybe i can help, i would not encourage his fear by telling him its ok and petting him when his fear is present, he will only get worse. I would use a leash and tie it to your belt loop on your pants and go about your chores and when things scare him ignore the behavior, and as he shows confidence reward it. maybe he dont like treats but string cheese has always been a great hit with my pibbles, i break a peice off in my mouth and reward. having him on a leash attached to you will gain his trust and also help him pay attention to you. good luck and let us know how he is progressing. also if hes on a leash he cant run and hide..
