Here is an English translation of the voiceover exchange between the two reporters in the clip (translation courtesy of Toshiyuki Kitamura):

We are in Arahama area. Looks like there is a dog. There is a dog. He looks tired and dirty. He must have been caught in the tsunami. He looks very dirty.

He has a collar. He must be someone's pet. He has a silver collar. He is shaking. He seems very afraid.

Oh, there is another dog. I wonder if he is dead.

Where?

Right there. There is another dog right next to the one sitting down. He is not moving. I wonder. I wonder if he is alright.

The dog is protecting him.

Yes. He is protecting the dog. That is why he did not want us to approach them. He was trying to keep us at bay.

I can't watch this. This is a very difficult to watch.

Oh. Look. He is moving. He is alive. I am so happy to see that he is alive.

Yes! Yes! He is alive.

He looks to be weakened. We need to them to be rescued soon. We really want them rescued soon.

Oh good. He's getting up.

It is amazing how they survived the tremendous earthquake and tsunami. It's just amazing that they survived through this all.

these are moments in life that we have to wait for someone. and you know that it will all be worthwhile, taking care of the injured pet/person that you know. this is called compassion and loyalty. i wonder why people in this world have so much free time to do unnecessary stuff, like making fun of people, bullying people and hating people... life is really too short for you to do those things. enjoy your life while you can. but don't regret what you have done, because what's done is done. you can never go back in time to fix it. treasure what you have right now...
