 This pattern is most easily seen on Mahogany dogs, although any Basset colour pattern may express the EM allele, except for "red and white" or "lemon and white" due to e/e.Many Bassets have a clearly defined white blaze and a white tip to their tail, intended to aid hunters in finding their dogs when tracking through underbrush.Like all dogs, the Basset Hound's coat is naturally oily.
