The insane craze for dog ice-cream

During the few hot days we had in June, I came across my first tub of dog ice-cream nestled among the Häagen-Dazs in my local supermarket. Scoop’s vanilla: ‘Tubs that get tails wagging.’ My first thought was that it was a joke, or perhaps for people who identify as dogs. So I looked it up as I stood in the queue, and it was as if a door opened onto our national psychosis.
