My family and I have recently rescued a Jack russell Rat terrier from the National Mill Dog Rescue (NMDR). She is about seven years old and they believe she has had about 16 litters in her lifetime. When we got her she was very skittish and scared. She would jump every time someone tried to touch her or pick her up, especially if she was touched on her hind end. I've been working with her and she has gotten a lot better over the past two or three weeks that I have had her. I am working on getting her house trained and all that but there are a few things I am stuck on. For instance she is doing the 'I'm scared of my food Routine.' everytime anyone but me goes near her when she is eating or tries to feed her. the other thing is that when i try to teach her the basic commands like Sit and down, she doesnt have any motivation to do the commands, She doesnt eat the treats when she does something good and she doesnt seem to respond when I give verbal/physical praise, I've thought of trying clicker training, but I also see negative sides to it, and the noise might scare her. She is learning how to be a dog again but I need the help.
