Around 1973, my wife was living in Chicago and was about 11 years old, at the time. The area was inner city Chicago; not near the lake or the woods. It was Summer and she was spending the night with her girl cousins, in the basement bedroom of their house.
In the early morning hours, around 4:00 AM, the dog was growling and woke them up. Those type of basements have windows high on the wall. In one window, my wife saw something looking in. It was difficult to make out exactly what it was, but there was enough light outside from a street light to see the outline and movement of something looking through the window. The 3 girls all screamed, which woke and brought the 2 older boy cousins down, to see what was going on. The girls told them what they had seen and the boys, who had been sleeping in their clothes, ran out to investigate.
The rest of this is their own account, which they reported, a short time afterward. They saw “someone” running away and they chased after him. It took them a minute or so to get a good look at who they were chasing, because of the sparse lighting in the area, but they said what they saw looked like a large werewolf. They thought it was someone trying to pull a prank; a man wearing a very realistic werewolf costume; dismissing the possibility that it was real. They lost sight of it and eventually returned.
So, that is about it. Knowing what we know now, we both think it must have been a Dogman.
