A previous study failed to find evidence that dogs could use olfactory cues to discriminate between 1 and 5 hot dog slices presented on a single trial (Horowitz et al., Learning and Motivation, 44, 207–217, 2013). In the experiments reported here, multiple trials were used to test dogs’ ability to use olfaction to choose one of two opaque containers under which a larger number of food items was placed. In Experiment 1, dogs chose between 1 and 5 hot dog slices. In Experiments 2 and 3, we examined dogs’ ability to discriminate between numbers of hot dog slices that varied in the numerical distance and the ratio between the smaller and larger quantities. Experiment 4 explored olfactory discrimination between quantities of a different food, dog kibble. Experiments 1–3 all showed that dogs used olfactory stimuli to choose the larger number of hot dog slices, but Experiments 2 and 3 revealed no effects of distance or ratio between numerical quantities. In Experiment 4, dogs failed to discriminate between 1 and 5 pieces of dog kibble. Factors that allow dogs to use olfactory cues to discriminate between quantities are discussed.

狗区分不同数量食物的嗅觉能力

之前的一项研究未能找到证据表明狗可以使用嗅觉线索来区分单次试验中呈现的 1 到 5 片热狗片(Horowitz 等,Learning and Motivation, 44,207–217, 2013)。在这里报告的实验中,使用多项试验来测试狗使用嗅觉从两个不透明容器中选择一个放置大量食物的能力。在实验 1 中,狗在 1 到 5 片热狗片之间进行选择。在实验 2 和 3 中,我们检查了狗区分数值距离不同的热狗切片数量以及较小和较大数量之间的比率的能力。实验 4 探索了不同食物(狗粗磨)数量之间的嗅觉辨别力。实验 1-3 都表明狗使用嗅觉刺激来选择更大数量的热狗片,但实验 2 和 3 没有显示距离或数值之间的比率的影响。在实验 4 中,狗无法区分 1 到 5 块狗粮。
