However, in real life, dogs trained for this purpose, do this kind of thing for a living. Here is a video of Koda, Karelian Beardog working in the Wildlife Management Program in Alberta, Canada. At four months of age, she is detecting and finding fish hidden in a plastic bag along a river bank…. similar to a situation involving a poacher.
As you can see, she has no trouble detecting the odor and locating it and remaining at the scene until her handler arrives to reward her efforts.
