Yes is not unormal, because in the early days, they showed some bleu ones and breed with them, just like with the Thia Ridgeback, there are also gray, black and brown ones, and mutipule crowns are also okey. But I do think when they set down the breed, that they make disisions what they really wanted, wich color, wich ridge, and than put that in a book, just like with the ridgeback, but the colour will be in the gene's, and pop out so now and than when they are further in the breed. But is that something to be shamed of, no I know fore sure not. I rather have bleu in my line than other strange or bad thinks.
But I hope more breeder will be open in this, and put down all faults on the site, so that we can learn from that combination, and not make the same faults as they did, or make the same combination as they did because the offspring were so good. We can all learn from ona a other, and put some ego away and say to the other one you did very well, I will make or I will have the same stud dog or combination as you do. That keeps the breed in good health I think, but maybe I am to fare in this.....I hope only some day...
