My dog Dargo is a Golden Retriever, and he is 7 years old. Bout a year ago, he spotted another dog and its owner and chased after it, dragging me and pulling me down our driveway (which is a hill of rough concrete). I ended up with a few big scars, and ever since then ive been terrified to walk Dargo. Whenever I do, Im on edge, I keep trying to pull him really close to me, and if any person or dog is anywhere in sight, i get extremely scared and end up just going back home really quickly. I cant walk him at night since its too dark and everyone in the house goes to bed early. What can I do to be less anxious and scared?
