In video footage, she looks withdrawn. She also had mange with a severe skin infection and was loaded with intestinal parasites and fleas.

But after many baths and medication treatments she began to improve.

Dr Karri said: “There is a point where you can tell these animals have accepted their fate and given up hope. She was there. Scared and depressed. It only took a few days of attention for her to realize we were there to help and she turned into a puppy again!"
