This one seems fake to me. The whimpering sounded like it was added in later, as it's postition and volume in the mix doesn't seem to change and it just doesn't sound like it's in the same environment. I would imagine the dog would react more as well.
I was on a woodland path once, late evening, getting well into dusk, and I suddenly heard loud crashing and screaming sounds coming from deeper in the trees. In terror I ran, but I ran the wrong way meaning I would have to cross a river (Thames) and walk about five miles to return to right side over the next nearest bridge, to get back to my car. I had no choice but to turn around and run as fast as I could back to way I came. It was stupid, as it would only have been a wild animal (foxes I expect) but your mind plays tricks when you can see what's making the sound
