Brindle is a coat coloring pattern in animals, particularly dogs, cattle, guinea pigs, cats, and, rarely, horses.
The brindle pattern may also take the place of tan in tricolor coats of some dog breeds (such as Basenjis).
[1] Brindle coloring in horses is extremely rare and most commonly caused by pigment concentrating along Blaschko's lines during fetal development.
One heritable brindle pattern in a family of American Quarter Horses was identified in 2016 and named Brindle1 (BR1).
Male horses have sparse manes and tails but do not show a striped coat texture pattern.
[2] Brindle coloring consists of irregular stripes extending vertically over the horse's body and horizontally around the legs.
It usually does not affect the head and legs as much as the body, with the heaviest concentrations of brindling being on the neck, shoulders and hindquarters.
At the Zoological Museum of the Academy of Science in Saint Petersburg, a Russian cab horse of brindle coloring from the early 19th century was mounted and put on display due to its rarity.
For crested geckos, the term "brindle" is used to describe a morph with darker stripes of color.
[6] In William Shakespeare's play Macbeth, the opening of act 4, scene 1, is often taken to refer to a brindled cat in the sense of coat pattern as described in this article, because it does contain the word "brinded": However, in this context – Elizabethan English – the word "brinded" was used to mean branded, as in marked by fire.
