A 20-year-old man in Vietnam came across a tiny puppy that wasn't breathing. Even though he has no CPR training, he knew that he had to help. Repeating what he had seen in movies and TV, he kept compressing the puppy's chest and used a water bottle he cut in half to breathe air into the puppy's lungs. Remarkably, it worked! The little pup was up and walking around again, ready to tackle his second chance at life.
