Each dog starts running towards the dog immediately anti-clockwise to it.Apologies for not addressing the problem mathematically, but the experimental scientist knows that whilst small children follow a pursuit curve, dogs are actually better hunters and tend to run in a straight line towards a predicted intercept. Eventually, some children learn the trick and turn into good cricketers or footballers. David Beckham's exceptional ability as a midfielder was being able to make long passes to an intercept so that wingers and strikers could run on to the ball at full speed in a straight line.
Late edit: it's also the art of a fighter controller!
