I've had this girl about 20 months, the vet thinks she is between 4 and 6 years old, I was given no background or history with her, she is a lovely lady, very good with children and disabled people. She's still a little unsure of some men but that's a huge difference from when I first got her. She is still quite nervous most of the time but even when she seems relaxed she still flinches when you touch her. I've tried being slow or waiting till she fully acknowledges I'm going to pat her and the flinches feel shallow but they are still there. And sometimes she looks at me so apprehensively like I'm going to do something to her, can anyone else who has had a rescue dog tell me if this will eventually go?
