concerning newfoundland dogs is there such a thing as a siver(color) newfoundland

We can engineer any coat color, length, quality that we can come up with by crossing breeds, in-breeding or selectively breeding recessive qualities.

There was a Russian study of producing a breed of farmed foxes to make them more "tame" and manageable - but by selecting the more "tame" and breeding for that selection - over a period of generations the foxes looked more like dogs, were more friendly but the quality of the coat changed so much that the stock was no longer useful for farming.

There is currently a new line of Silver Labrador Retrievers - and I'm sure that a person is ready to make a "rare looking" dog for profit.

You have to be aware of genetics and the effects it has on behavior.

Color

Color is secondary to type, structure, and soundness. Recognized Newfoundland colors are black, brown, gray, and white and black.

Solid Colors--Blacks, Browns, and Grays may appear as solid colors or solid colors with white at any, some, or all, of the following locations: chin, chest, toes, and tip of tail. Any amount of white found at these locations is typical and is not penalized. Also typical are a tinge of bronze on a black or gray coat and lighter furnishings on a brown or gray coat.

Landseer--White base coat with black markings. Typically, the head is solid black, or black with white on the muzzle, with or without a blaze. There is a separate black saddle and black on the rump extending onto a white tail.
