Lia was found on the streets on LA near a dumpster, and after she was rescued, I had her flown over to NYC. Here is what she looked like (below) when she first came to me. It seemed as though she didn't want to live anymore because she was extremely thin and ill. She wouldn't eat, barely had the energy to walk, and was fearful of human beings. :(
For the first month or so, she would always step back whenever someone approached her. It was an automatic reaction she had which I believe came from being abused by someone (I could tell by her injured nose and expression). Therefore, I made sure to approach her very gently and slowly in a low position, letting her know that she would be okay being around me and that there was nothing to be scared of.
Lia always hid in the corner of a room, so I got her a little "home" so that she could have her own space for a while. I no longer need to use this today, but back then, it was very helpful because I could still see what she was doing from a distance (since it's see-through), and she could also see her surroundings while feeling comfortable. She didn't need to be worried of who or what may come into her private space, so it allowed her to rest well and eat more at her own pace.
She started opening up to me as the days went by, and although it took several months, she started to enjoy walks again! (In the very beginning, I had to wear clunky shoes to attract her attention and have her follow me.) She now runs along with my brother's doggie as well!
Now, she begs for food with twinkling eyes, runs with me at full force at the park, and sleeps in my arms at night. I truly could not be more thankful that she came into my life, and I hope that she feels the same. :) It is absolutely life-changing to see her grow (both mentally and physically!)... and I hope that you can rescue or help spread the word about adopting and the importance of caring for these innocent furry friends, too.
