If tomorrow everyone woke up and treated everyone they will meet like puppies, how would the world be different?

It will never happen, but imagine that when everyone wakes in the morning every person they meet they will treat like a puppy. I can’t think of anyone that doesn’t like puppies, even if they do not want to own one, they like or love them; if they see a puppy that looks thirsty, they give him a drink, if hungry, they give her a snack, if sad, comfort, etc. What if people woke up and treated every other human they met with as much concern, compassion, and well-being as they would a puppy, how would the part of the world you live in be different?
