While the iconic Newfoundland is solid black, the breed standard (AKC, CKC, KC, FCI) recognizes four color varieties:
Black (B) dominant to brown (b). Dilute (d) recessive creates gray (dd) from black, silver from brown. Landseer pattern: piebald (sp) homozygous. Reputable breeders test for coat color genes and prioritize health (hip/elbow dysplasia, cardiac, cystinuria) over color.
Historically, black preferred for water work (visibility in rough seas). Landseer's high-contrast pattern aided spotting in surf. All colors share the breed's defining traits: massive bone, webbed feet, water-resistant double coat, sweet temperament, rescue instinct.
Brown puppies often born darker, lighten. Gray puppies may appear black at birth, clear by 8–12 weeks. Landseer pattern visible at birth. Final color confirmed by 1 year.
