He is some kind of cross, I'm sure. I have no idea between what. My pet theory is Arab/Shetland.
If it's signifcant, he also has black gums. 0.o In the words of his former owner: "Holy s***t, he's part chow!"
Also, what kind of crazy color is this beast? He's got some spotty dappley funk going on. Reminds me of moldy bread, in the best way possible.
