Social transmission of food preferences has been documented in many species including humans, rodents, and birds. In the current experiment, 12 pairs of domestic dogs (Canis familiaris) were utilized. Within each pair, one dog (the demonstrator) was fed dry dog food flavored with either basil or thyme. The second dog (the observer) interacted with one demonstrator for 10 min before being given an equal amount of both flavored foods. Observers exhibited a significant preference for the flavored diet consumed by their demonstrators, indicating that dogs, like rats, prefer foods smelled on a conspecific's breath.
食物偏好的社会传播在包括人类、啮齿动物和鸟类在内的许多物种中都有记载。在当前的实验中，使用了12对家犬（犬属）。在每一对中，一只狗（示范者）被喂食添加了罗勒或百里香调味的干狗粮。第二只狗（观察者）在与一只示范者互动10分钟后，被给予等量的两种调味食物。观察者对其示范者食用的调味饮食表现出明显的偏好，这表明狗和老鼠一样，更喜欢从同种个体呼吸中闻到的食物。
