I saw this while walking to the gym and decided to film it.

I saw a dog chasing ducks in a local river and was surprised when the duck appeared to play dead to escape the dogs attention. I didn't realise ducks did that. You can hear the dog's owner shouting in the background while her pooch completely ignores her because it's busy having fun in the river.
