The world's first ice cream van for dogs will open for business at a “pet party” in London's Regent's Park Saturday. The van will serve canine-friendly flavours such as “Dog Eat Hog World” - a chicken sorbet - and “Canine Cookie Crunch,” a more traditional vanilla ice cream, albeit sprinkled with dog biscuits. Sally Bezant of Boomerang Pets Party, said a team of pet nutritionists had been through a complicated scientific process to determine the tastiest and safest flavours for the dogs' dessert. And although the unusual flavours were tested on a panel of dogs, they can be eaten by humans.
