This is located next to the Black Dragon panel. It might be that the "praying dog" image (as it is known) may not be a dog at all but a person praying toward a location where the sun would be expected to be at equinox. Unfortunately, age and wear have created the illusion of a dog and that idea has been reinforced by the recent use of chalk outlining. On the other hand, it might simply be a dog in solar devotion or in some other unknown act.
