Hi Danny and welcome to the board.

Interesting picture, where did you get it from?
If I had to take a guess I'd say there's definitely Shar Pei involved, I have some historic pictures of Shar Peis somewhere, where they're not so overdone with the wrinkles and they look quite similar. I'll try to find them when I get home from work and post them here.
What exactly do you mean by Zulubull? Never heard of it before.

Take care, regu.
