Don't know how it can be termed silver, as it is dilute Brown, which in Rabbits would be called Lilac, and in some dog breeds is termed Isabella (Dobe). It is the same colour as Weims are.
I suppose you could conceivably also get blue if these were bred to Black?
The more colours a breed has the more scope there seems to be for breeding just for colour instead of a decnt specimin.
I am glad that my breeed only has one colour pattern, and even then there are preferences among some people for light or Dark shade, but at least when judging or picking puppies colour isn't a particular factor. As long as tyhe colour is clear and there is minimum white.
