Anyways I'm having some trouble with her and I'm assuming it's all because she's scared. She's a very submissive, flighty dog first of all. She's very sweet and loving with me. I can go outside and she'll start wagging her tail and walk over to me now. But today when I put her in the basement. She wouldn't let ANYONE out. She just sat on the steps, bared her teeth, and growled. My dad yelled upstairs for my mom, so she came outside and opened the door from out there, so she could run into the backyard. She called me and when I came home I went out into the backyard again. She of course was very sweet to me, I gave her a few treats, rubbed her belly, and she was running around trying to play with me even. I have her locked outside in a kennel for now. My mom wants to send her to the pound, she keeps telling me that if I take her to the Humane Society she's just going to get put to sleep. So I have 2 weeks to atleast try and make a change in her personality. What can I do to help her?

She is very, very sweet and loving. Honestly, I think she's just kind of shy and afraid, probably roughly handled as well.

Hmm something about her background. The people had her since she was a pup. She was housetrained and everything, but they threw her outside when she got to big for their house and has been leaving out there for the past couple of months. I don't want to have to give her to a farm or anything like that, I'd like to see her in the house for sure. So repottytraining her is a must, also I haven't introduced her to my dogs yet, they've met through the kennel but that's about it.

Anyways how do I go about socializing her? What else should I know about helping her and not letting her be aggressive anymore?

Hmm, the thing with something like this is that it is most likely fear based aggresion. She's been through a big change the last couple of days and that's bound to freak even the most confident dog out and a soft dog even more so. She's fine with you because she most likely associates you with good things like treats and belly rubs.

Perhaps you could try to get your parents to slowly gain her trust by taking turns feeding her or playing with her so that she sees them as positives not scary things. She probably hasn't had much interaction with people in the past little while (just going by what you were saying) and doesn't quite know if these things that walk on two legs can be trusted or not.

Also if she hasn't been in a house in a little while that could have also contributed to the problem, she was in a strange place with strange people and it just got to much for her to handle. So you might want to slowly introduce her to the house first in one room and get her comfortable there and as she gains more confidence slowly grant her access to more rooms in the house...either that or I might suggest umbilical cording her to you that way she could still get used to the house but she would be with you who she feels that she is safe with.

Other then that the only other thing that I can think of are calming signals and tellingtons touch but those are used more to calm dogs down and reduce the stress level.
