Temptation

While playing video games, do you ever get into that zone where your friend could wave a hot slice of your favourite pizza directly under your nose and you'd be totally disinterested? That's the level of desire for source we want to condition in our scent detectiond dogs, and one of the ways we do it is indeed by luring them away from source with low-value food but clicking and treating with high-value food only when they return to source. Once the dog is totally disinterested in your bait (think video game analogy), gradually increase the value of your bait until he has absolutely no interest when you wave pizza under his nose.
