Let me sniff! Nosework induces positive judgment bias in pet dogs

Short Synopsis: The researchers compared how dog reacted to a new object after practicing nosework versus heelwork for two weeks. If the dogs were quicker to approach the new object, they were deemed “optimistic.” The dogs who practiced nosework were quicker to approach the new object than before the two-week nosework training period. Practicing heelwork didn’t get these results, so there’s something unique about nosework for this. The researchers suggest allowing dogs to spend more time practicing normal “foraging” behavior to help them feel more optimistic.
