Honestly this is a new one for me - I'm primarily a poltergeist and MIB researcher so Dogman isn't really my territory - but I did want to flag something that caught my attention reading through this thread.
There's an abandoned Victorian-era rail tunnel about 4 miles outside Durham city centre, and over the past 18 months I've seen three separate reports on local Facebook groups describing something large and bipedal near the entrance. Nobody used the word "Dogman". Specifically, but the descriptions are striking when you line them up against the American cases people post here.
What I find genuinely interesting is the tunnel specificity. Old limestone and sandstone tunnels create unusual acoustic environments - you get infrasound reflection, temperature inversions, electromagnetic anomalies from the old iron rail infrastructure still buried in the ground. We know from poltergeist research that EM fluctuations can trigger perception anomalies and even genuine physiological stress responses. Could that explain some sightings? Possibly.
But it doesn't explain physical evidence like tracks or the consistency across independent witnesses who've never communicated with each other.
A few questions worth considering:
Are the tunnels you're documenting predominantly pre-1900 construction?, Is there a pattern around specific geological substrate (limestone vs granite vs clay)?, Do sightings cluster around dusk/dawn specifically or genuinely random timing?
I picked up a decent thermal monocular (the InfiRay Clip-C clip-on) recently for ghost hunting work, and I'm half-tempted to do a proper overnight vigil at this Durham tunnel just to see what the baseline environment readings look like.
Has anyone actually attempted systematic environmental monitoring at a known sighting location?
