Me And My Shadow: Dog Follows Duck For Hours Through A Lake

You've never seen anything tailed as closely as this. Not even in the very best TV detective shows.

According to YouTuber bill bob, his friend's dog spent hours shadowing this duck in the water. And yet amazingly, as you can see, he never, ever makes a move for it. Someone give this pooch a medal (for restraint)!
