How does the color inheritance work in the Newfoundland?
The Solid Black is dominant, or BB. The Landseer is recessive to the solid black, or bb, and is the result of the piebald gene, which places the self-color on a white background. Solid Bronze is recessive to black, and the Solid Gray is a dilute of black. Care must be taken when matching dogs with recessive genes, as the piebald gene will result in a solid color and white dog. Where the solid color is black, the Landseer results, which is a color allowed by the standard. However, if dogs with Brown or Gray backgrounds are bred with a Landseer, the possible results are a Bronze and White or a Gray and White dog, both of which are explicitly disqualified in the standard.
