Scent Work: What is one of your dog's favorite things to do? Sniff stuff, right? No matter the breed, all dogs have a sense of smell 10,000 to 100,000 times better than ours. In this event, the dog takes the lead in tracking down the target odor which is hidden within a designated search area. Cotton swabs saturated with essential oils are the targets. When the target smell is found, the dog signals to the handler, who then calls it out to the judge. Fun and impressive.
