There are numerous dog face images in the fur and area surrounding these dogs. One face that I feel is particularly clear is on the back of the dog in the second photo (just above the other dog's snout). Below is an enlargement. I haven't outlined or enhanced the photo because there are so many angles. Just see if you can see it.




And in this crop from the first photo, you can see the peach coloured snake emerging from the orb.





My theory based on studying my photos is that natural spirit form is serpentine but it can coil into a ball/orb, or other various forms.
