I was fortunate to be linked to this article and video; it's about Tessa, a dog who was once both blind and unable to walk, who was dumped at a shelter. She was about to be euthanised when a kind soul, Annie Hart, walked into her life:
I am delighted that Tessa recovered and now has a shot at life; however, I am angered that her original owners gave up on her rather than healed her. If you have a pet, it is your responsibility to see to its health — you don't quit: you care for your pet even if it is terminally ill. In fairness, it is possible they were no longer able to take care of Tessa rather than felt the need abandon her; the article's content about them is scant.
I hope that Tessa is adopted by a loving and caring family. Kudos to Annie Hart for her hard work in treating Tessa and ensuring she lived. Enjoy the article and the video.
