We have adopted a 6 month old puppy from a shelter. When she was 10weeks old she got very ill. From what we read this occurred during her Fear Imprint period. She currently is intimidated by all people. She is pitiful. She won't leave her cage, when we force her out, she hides away in a corner. When we approach her, she shakes violently. She is not an aggressive dog. She is extremely passive. We have read about shy dogs and the suggestions were to make sure we don't reward her shy behavior. We should only scratch her and love on her when she is acting more brave. Our problem is, she is always scared. She is never brave. We are trying to work on gaining her trust. I don't want to screw that up by avoiding her, but I don't want to cause her undue stress either. Right now, she just makes us sad. She howls all night and is pitiful during the day. Any suggestions would be extremely appreciated. We have had trouble finding good info, but I'm sure we aren't the first to deal with this problem.
