He actually looks quite like our chocolate. Best of luck with him.
OH and i'm in the "accidental granite combo club" tooWe made lemon pastel x granites without even knowing the granite was present/genetic.
our choc (08) for comparison, he's currently breeding away too Bad pic, only one I can find right now.
Hers some of our 09 genetic granites (I don't think your boy is a granite):
pastel granite:
Black pastel 09:
Hope some of these help for comparison.
To my eyes thats a normal with your best chance of it being anything else either a chocolate or sable type animal.
