"Dog ice cream has existed, in more limited options, for decades. In 1979, the late Ohio State University professor and animal nutritionist William Tyznik formulated cups of vanilla ice cream for dogs and called them Frosty Paws. With a focus on health, Frosty Paws used soy flour and dry delactosed whey, skipping the added sugars of human ice cream, according to a 1989 UPI report released following the licensing of Tyznik’s creation. Frosty Paws was later acquired by Nestlé, which sells it through the Purina brand today." - Bettina Makalintal
