Life can be lit even amid terrible darkness, and there should be hope and courage. The dog's owner's trust was broken that he would be able to treat her. He might be thought that better to buy a new dog rather than treat her. So he may decide to throw her on the street. But she never gave up. She didn't lose her hope. Finally, she has got a new life and it has been possible from your kind support.
Think before abandoning your pet, imagine, it could be you, and your son/daughter kicking out you form the home.
