Canine that have been teased sat, laid down, and backed away the barrier extra continuously. The outcomes have been comparable throughout totally different canine breeds, ages, and intercourse.

Within the clumsy trial, the canine additionally wagged their tail extra on their proper aspect, a behaviour recognized to be related to canine which might be blissful and relaxed. “They’ve extra optimistic feelings in the direction of the clumsy experimenter, which could point out that they certainly perceive that the experimenter is keen, however simply too clumsy, to offer them meals,” says Völter.
