I know, there will be a set coming this fall with white shepherds (
4237), but as I have customized these animals already several weeks ago (and I'm now updating my homepage with making several pics of things not shown so far) I post them anyway.
In contrast to albinos (animals, which lack color pigments and for this often have a delicate healthy) the white shepherds are a breed on their own. It has the same nature and characteristics like the German shepherd, from which, by the way, it is descended. He can take him on any time, even has been preferred as shepherd because of his white fur, which makes it more easy to distinguish from wolves.
