Derbyshire lad weighing in here - we don't have a Mississippi but we've got enough moors to know that when multiple credible witnesses start reporting the same thing independently, you stop calling it coincidence and start calling it a Tuesday.
What strikes me about the Mississippi cluster is the consistency of the descriptions. Upright, bipedal, distinctly canine features, typically between 6-8 feet. That's not the kind of detail that spreads through casual Chinese whispers - people aren't choosing the same specifics for drama.
A few things worth considering:
The river corridor itself acts as a natural wildlife highway, so something moving along it isn't inherently bizarre, Increased trail cam usage (Bushnell, Stealth Cam, the lot) means more eyes in the dark than ever before, Are we seeing more sightings or just better reporting infrastructure?
I've spent enough nights out on Derbyshire's edges with my thermal monocular watching shapes I couldn't immediately explain to know that the brain doesn't just manufacture these things wholesale. There's usually a something - the debate is always what that something actually is.
The Dogman phenomenon specifically interests me because it predates internet cross-contamination. These accounts go back decades before everyone could accidentally borrow each other's descriptions.
So yes - I think something's genuinely happening along that river corridor. Whether it's a known animal behaving strangely, a genuinely unclassified species, or something that'd make a cryptozoologist's eyes water, I couldn't say.
Anyone actually on the ground near the Mississippi want to share firsthand accounts? Raw data, please - not what someone told someone else in a Facebook group.
