Ten months ago I rescued a 2 yr old female Yorkie. Her history as told to me was that she was a breeder in an Ohio puppy mill all her life. She never had a litter because of a prolapsed uterus. She will cuddle with me on the couch or bed, and play with me if I am on the floor. She will only come to me if I am on the floor. She will run and hide if anyone, including me, walks into a room. She will also run if I make the least little noise or movement when she is in my bed at night. She jumps down and runs off, then comes back up after awhile. She likes to play with my other Yorkie, a male, but will not eat in the same room as he is. She will only eat in my bedroom with the door closed. I don't understand the running away part, especially since she is comfortable around me. I have asked my vet about giving her something to help with her anxiety, but he told me to give her benedryl, which does nothing.
Is there anyone who can give me some tips to gain her trust? I praise her when she doesn't run away, which is very rare. She is so sweet, but so scared and anxious all the time. I want to help her.
