Number 10. Tillie. When her adopted canine sister, Phoebe, got stuck in a cistern, Tillie sought help. Though it took her a week to convince someone to follow her and lend a hand, Phoebe was rescued and the two returned home soon after.
Number 9. Mahe. The black Labrador is almost always by his best friend James' side, even when the 9-year-old autistic boy is in the hospital. Following a stressful round of medical tests, Mahe comforted James by jumping on his bed and curling up close beside him.
Number 8. Simon. At just 1 year old, he'd already experienced unspeakable cruelty, but still found it within himself to comfort a dog that had been through some hard times as well. Upon meeting Sammie, who was recovering from being shot and dragged behind a car, Simon placed a reassuring paw over his.
Number 7. Smiley. Born without eyes, the dog has devoted his life to helping others with disabilities. While people generally respond well to him, some time ago he accomplished what some may consider a miracle – he made a man unable to communicate smile for what may have been the first time.
