We rescued a 2 year old golden retriever in late February. She's a beautiful sweet dog but still very timid. She has made great progress in the last 2 months but jumps and startles if anyone moves too quickly around her. We are starting to work on basic behavioral training with her. Training with treats is difficult because she will not take a treat if she is too nervous. Clicker training is difficult because the clicking sound startles her. I think choke and shock collars are a huge no for a dog that has been abused. We give lots of praise for good behavior but have to be careful not to overwhelm her. We also have a 3 year old English Cream Retriever who is well trained. We try to use her to model behavior but that isn't enough on it's own. I'm looking for recommendations from others who have rescued. What training resources have you used and like best?
