Leo the dog is officially our favorite hero thus far because the dog did such a noble act that we couldn't think of him any other way. When his humans' home in Melbourne, Australia, caught fire, the family escaped unharmed with one of their dogs, but Leo was nowhere to be seen.
Firefighters went inside to find Leo, and what they discovered was sweet and brave: Leo is lying on top of four kittens, keeping them out of the fire. When they arrived, he had lost consciousness, but they were able to safely remove them from the flames and provide Leo with the oxygen needed to regain consciousness.
When Leo regained consciousness, the first thing he did was lick the kitten friend who loved him!
