Is this the end of the world as we know it?
Flying pigs might be something of a concern but despite what Facebook says, I haven't seen any. Grass eating dogs on the other hand, are more common than fake news.
Now some people might think the reason I see a lot of grass eating dogs is that I see a lot of sick dogs - which is true, BUT, I also see a lot of healthy dogs that also eat grass.
“Why is it so?”
said a famous TV science guy and the truth is: we don’t know!
