I've heard it said that Jack Russells are the most intelligent dogs in the world. However, I've always had something against the little runts.

For whatever reason this particular breed of dog seems intent on snapping at my heels when I'm on my runs. I suppose that I should be grateful that I don't attract Rottweilers instead, but there's something incredibly annoying about being chased by some overgrown rat with a Napoleon complex. What's particularly annoying is that the thing doesn't realise its place in the natural pecking order. At any given time I could simply stop my run, turn around, and drop-kick the little bugger over the nearest wall (not that I ever would).

That being said it's no wonder I take such satisfaction from the following clip.

Now I can see Sarah's shocked face, so remember that while it may be funny … it’s not the done thing!
