I’ve just spent a day looking after our one-year-old vizsla and, to be blunt, I have some sympathy with Michael Heseltine’s decision to strangle his mother’s alsatian. Not that my wife is out of town. Rather, I’ve just got a new job as director of the New Schools Network, a charity that helps groups set up free schools, and Caroline argued that because I’ll now be spending so much time away from home I am morally obliged to take on the lion’s share of dog duties before I start.
