Just for fun I'm curious what others think about this video.
At first I thought this was a dog, by it's size and the way it moves, but when it moved closer to the camera it turns to the side I question if it's a dog.
I'm thinking either something like a Weimaraner or a freakishly large Bobcat since the tail seems to be bobbed. https://en.wikipedia.org/wiki/Weimaraner
Enters frame at 23 seconds, good side profile at 43 seconds. The youtube version is not as clear as the original, in the original the ears appear to be short and pointed.
Here's the video, have fun.
