I have a 2 year old Rottweiler that is scared of everything from a flag like sign flapping in the wind or even a sudden door from a business opening or a bag blowing in the wind.... I have found a solution that has kept him from running out into the road but I don't know how to stop him from being skittish or try to run. He loves ppl and playing. i have tried just walking away like nothing happened after we stop and let him go thru the motion then walk away. idk how to completely nip it in the butt. these are everyday things we have to deal with living where we live at. I need some help with this. any ideas?
