That is a beautiful dog!
I think there is one on BPO who is similar in color, somewhere between merle and brindle. The dog's name is Moose I think?
"Back yard bred" Danes often show up in very mismarked colors. Of course they are gorgeous animals, I love all Danes, but you have to wonder what else the "breeder" ignored besides color matching when they chose the breeding pair...
I am constantly crossing my fingers that Leeloo (our rescue mismarked Dane
) doesn't turn up to have any horrible genetic problems. So far all we know is she has some deformed teeth in the back of her mouth. Otherwise she is very healthy.
