Street dog Half her face had been eaten by maggots :

Two deadly conditions meant survival was unlikely for this emaciated young street dog. Half her face had been eaten by maggots and she was also suffering from the often- fatal canine distemper virus. For many days we prepared ourselves for the chance that she would "go down hill" because fighting that virus calls for incredible strength.

To have your strength simultaneously used to heal from a devastating and huge wound, it's just hard to imagine anyone surviving. Her body seemed so fragile and defeated when we rescued her. But her strength must have come from her soul. After weeks of treatment and love, meet Juliet now!
For street animals in anguish, let's give happiness.
