Brindle Explained
  A Brindle Dog carries the Gene Formula (ayayBCDebrgmrSt) and will reproduce its color if bred to a dog of the same color. It is dominant over most colors with the exception of dogs in the (A Series) which include the solids or solids with white (black , chocolate, apricot, clear red or lemon, White, Kerry Blue and Silver) or the color Merle. Being dominant in nature a single (ebr) gene is all that is necessary to visually see the color in the offspring. It varies in color from a deep rich striped pattern with multiple colors to shades of chestnut, mahogany, fawn, blue, and seal which is almost black. The seal color sometimes needs close inspection to distinguish between it being a brindle or a black dog.  The color black will dominate the brindle color and if in combination with the black and tan (at) gene the dog will only show the brindle patterning in the areas of the tan color. This has sometimes been called "Trindle". There is generally no mistaking a Brindle color dog because it has very flashy stripes and a definite pattern.
