Where is the black spot exactly? Upper or lower abdomen?

Hi Bryndewey:
I'm glad that you found The Squirrel Board! Welcome! Would you please post several photos of this "spot" from different angles and at least one that is straight on. How did the "spot" develop? Did it just show up one day and remained unchanged or did it come on gradually. Is the "spot" on the skin or the fur or both? Is there anything unusual about the skin in the area of the "spot" such as swelling, a wound, drainage or anything else?
Regards,
