I feel he could still change a bit, as when we first got him the black areas were very distinct and large, already the area on the side shown has broken up more and in all the other areas there are patches of silver coming through.
I guess Merle is a funny one, I was looking for some similar merles earier, and he's quite close Ch. Pepperhill Blue Fizz who was a breed record holder with 21 C.C.s, with the darker merling (although admittadly not quite as large black patches). I have a picture here but not sure if I can post it.
