The dog in this video definitely has some concentration. Check it out. The dog in this video is stalking a wolf. The music is great in this video, too. It's cute and funny all at the same time. Now, I don't want to give away the ending, so, scroll to the bottom when you are done watching the video to read more.

So, how long did it take you to realize the wolf wasn't real? I have to say it took me so long to realize the wolf was fake. It seriously took me about a minute to realize that the wolf wasn't moving. I was just thinking to myself the whole time, "Wow, that wolf is really, really still." According to the description of the video on YouTube.com, the dog stalked the "wolf" for six minutes. The video is edited down to just over two minutes. Wow, that's some definite concentration.
