Sometimes less is more for hungry dogs

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.

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.
