I think it is sometimes easy to look at animals and not realize that they are a bit of purity in an impure world. People want to write off their actions as all being based on the need to survive, so let me ask you, what is the dog doing in this video that will ensure it survives? Nothing. The dog simply sees that this fish is struggling, and somehow is aware enough to try to get water on the fish. It is as simple an act as one could do, yet it is impossible to watch the video and not get hit right in the feels. Don't worry if you cannot understand any of the background dialog, as this is all happening in Thailand.
Though apologies to anyone who finds this video sad, that is not how you should take it. You should walk away from this amazed at the empathy one animal felt for another, even of a different species. They say empathy does not exist within the animal kingdom (they being most psychologists), yet here we have a one minute video that proves that not to be true.
I know some humans who could learn a thing or two from this dog about how we should treat one another, even if we are a little different. Very powerful stuff.
