Two-bowl choice tests were used to examined preference of puppies aged two to four months for compounds tasting sweet to humans. Puppies found many, but not all of the compounds highly palatable, and were sensitive to both type and amount of sugar or nonnutritive sweetener contained in a semi-moist dog food recipe. Lactose, fructose, and sucrose were well accepted, whereas maltose elicited indifference or rejection. Sodium cyclamate, but not sodium saccharin, was preferred at some concentrations to 15 percent sucrose sweetened semi-moist food used as the standard. Solutions of lactose, fructose, glucose and galactose were preferred to plain tap water.
采用双碗选择试验来检测2至4月龄幼犬对人类尝起来甜的化合物的偏好。幼犬发现许多（但不是所有）化合物都非常可口，并且对半湿狗粮配方中所含糖或非营养性甜味剂的类型和含量都很敏感。乳糖、果糖和蔗糖很容易被接受，而麦芽糖则引起无偏好或被排斥。在某些浓度下，环己基氨基磺酸钠（而不是糖精钠）比用作标准的15%蔗糖甜味半湿食品更受青睐。乳糖、果糖、葡萄糖和半乳糖溶液比普通自来水更受青睐。
