Brindle: A marking pattern used to describe many breeds, usually in conjunction with another color. Layering of black hairs in regions of lighter color (usually, fawn, brown, or gray) producing a tiger-striped pattern. Brindle is often used to describe Great Danes, Bulldogs, and Boxers. In Boxers, reverse brindle may occur; i.e., there is such a heavy concentration of black striping that the fawn background color barely, although clearly, shows through (appears black with fawn stripes). Color definitions may vary by breed. Always check the breed standard for the definitive color description.

Brisket: Usually refers to the sternum, but in some standards it refers to the entire thorax.

Brittany Spaniel: A large pointing spaniel of a breed originating in France.

Britches: Longer hair found on the upper rear area of the legs.

Broken Color: Self-color broken by white or another color. Color definitions may vary by breed. Always check the breed standard for the definitive color description.

Broken-haired: A rough, wiry coat.

Broken-Up Face: A receding nose, together with a deep stop, wrinkle, and undershot jaw, as in the Bulldog or Pekingese.

Bronze: Used to describe Newfoundlands, this color is usually a tinge in a black coat caused by the sun. It is like the color of the metal of the same name, which can be described as a moderately bright, yellowish brown. Color definitions may vary by breed. Always check the breed standard for the definitive color description.
