Like any dog, Mylo is a greedy dog. He loves his snacks, to the point he’ll avoid his dinners and would rather go hungry in anticipation of his favourite snacks.
So it is with times like this that Kristina Pattison and Thomas Zentall of the University of Kentucky in the US tested the principle of dogs sometimes showing a “less is more” effect.
“Hungry dogs would be expected to choose alternatives leading to more food rather than less food. But just as with humans and monkeys, they sometimes show a “less is more” effect. Thus conclude Kristina Pattison and Thomas Zentall of the University of Kentucky in the US, who tested the principle by feeding baby carrots and string cheese to ten dogs of various breeds. The findings are published in Springer’s journal Animal Cognition.
The research was conducted on dogs that would willingly eat cheese and baby carrots when offered, but showed a preference for the cheese. However, when given a choice between one slice of cheese, or the cheese together with a piece of carrot, nine of the ten dogs chose the cheese alone. That is, they chose less food over more food.”
