Interesting picture.
Let's look at it a bit closer.......

So yes, there
does appear to be what looks like the shape of a dog. You can define what appears to be a head, torso and legs. What I find interesting is that this shape interferes with the woman's left leg, which should be visible the same way you see the right foot and shin, indicating the possibility of some sort of mass being present.
However, I am not saying at this point it is paranormal, but there again, I do not believe this is just pareidolia. Like Duke, I would like to see the actual recorded footage of this occurrence leading up to, into and beyond the still.
