We got our dog Earth from a shelter when she was a small pup. She was covered in fleas, extremely timid and afraid. We took her in as we just couldn't stand the sight of her there. We loved her and looked after her and she grew comfortable with us in the family. Though I've come to notice things about her, well noticed them since they started really but I had no idea what to do and asked for help but no professional knew, they said with love and care she would soon grow out of it. Well she is about 3 years old now and nothing has changed. I'll explain. When people come over, not just ones from anywhere, ones who have come over for ages now, Earth will be scared of them. She will go anywhere just to hide from them. We try hard to encourage her and she does a little effort but then the next time the person comes over again it's back to hiding. Another thing. I will be outside with her for ages and then I will go inside, note we have a screen door so that she can look through, and I will put on a hat or something or put up my hair or put a jumper on, then I will go outside and all of a sudden she will back away and bark at me as if I was someone she didn't know. She doesn't seem to like men very well either but I think that is because of the low voice, it's like a growl. Though I can not ask every guy that comes to my house to speak in a high squeaky voice. It would be funny but i do not think that is the right thing to do. At times she will bark at a shadow, or she will growl at something, one time she growled at a plastic bag in broad daylight and I wasn't too sure why. When I moved the plastic bag she was fine and wagged her tail, though the plastic bag was there for ages! I have no idea what is actually wrong with her. I love Earth to death and would do anything for her. She is fine physically and they say there is nothing wrong mentally. She responsed to everything else fine and she is always gentle. Very obiendient too. What to do?
