I asked a question like this a few days ago and didn't get any responses, so I'm asking it again. I have a 3 year old Great Pyrenees mix. She's very skittish, and is specifically fearful of new things, strangers, and cars. It's difficult to take her anywhere because of her fears, even if it's just around our block. It has gotten dangerous in the past, because she will try and flee when she's panicked and is strong enough that she has pulled me into the street before. She's also stubborn; if she sees, hears, or smells something that makes her nervous, she'll try and turn away. When I try to coax her back, she'll sit down and refuse to move until I go back with her. She ignores treats and toys while out in a place with too many distractions, so I can't use them. What can I do to help her calm down and not be so fearful?
