Brindle Markings

Q: I've heard the term "brindle" used many times. What does it look like?

An example of a Jack Russell with brindle markingsA: "Brindle" is a pattern of colors that is seen in the black, tan or brown colored area on a coat (see picture). You will not see it in the white portions. It is a repeating, wavy, tiger-like pattern of black or tan within those colored areas. It is a sign of foreign blood back in the dogs ancestry. For visual examples you can look up pictures of bull terriers, boxers, great danes and mastiffs in a dog encyclopedia. It is an unregisterable color and therefore the dog should not be used for breeding.

An example of a Jack Russell with grizzle markings"Brindle" should not be confused with "grizzle" (see picture), where black hairs are mixed with the tan.
