Been following this for a while actually. The cluster around the Michigan/Wisconsin border is hard to ignore at this point, theres been a noticeable spike in reports since around 2021 if you dig into the BFRO adjacent logs and some of the independent researchers tracking it.
My theory, and take this for what its worth, is that something about the Great Lakes region acts as some kind of anchor point. Whether thats geological, electromagnetic, whatever. Dense forests, freshwater on a massive scale, low population corridors. Good conditions for something to operate without much interference.
I drive long haul so I spend a lot of time on quiet roads at odd hours. Never personally seen anything I'd call a Dogman but I've had a couple of experiences in that general category of "something that shouldn't be there" near treelines in the early hours. Not in the US admittedly, more local to me over here. But the behavioural descriptions people give near the Lakes match up in ways I find genuinely interesting.
Anyone cataloguing the sighting coords? Would be curious to see if theres a pattern on a map.
