The original illustration for Barkley from 2003.
He and his species are designated in my notes as:
"Spidery-legged dog things, about the size of a wolf, covered in thick, mangy, deep green to green grey fur. They speak a language of sharp barks and hissing growls that is unnerving to listen to. While smarter then stone age humans, a lack of resources, including food and water, has limited their advancement."
