Well this is something that happend to be some years back.
I was walking my dog in the evening, and it was kind of late, so it was starting to get dark, and there is his park I often walk up to with him. And along the path that leads back to the partk there is this downward slope with a creek below.
So I am walkig along the path with my dog when upahead I see something sitting on the side of the slope, but it was dark and hard to make out at first I thought maybe it was anohter dog. I began to get closer and was currious becasue I could see it and it was not moving at all, just sitting there, and it looked this sort of slate gray color.
I began to inch closer to it, and as I got closer, I could see it looked as if it had no fur, and its skin was kind of leather like and all gray, and it was about the size of a large dog, almost like a doberman, and it was sitting still as stone, did not look in my direction or move at all, but I could start to hear this strange sound. It was almost like the sound of a heart beat, this deep low pulsing sound that almost seemed like a vibration.
