Bull Terrier Colors & Coat Guide

All recognized Bull Terrier colors, coat types, genetics, and how color can impact pricing and health.

Bull Terrier Colors Overview

White coloring is due to the extreme piebald gene, while colored varieties carry standard pigmentation patterns including brindle and red.. Breed standards outline which colors are accepted for conformation showing.

Color inheritance involves multiple genes—including the E (extension), A (agouti), K (dominant black), and B (brown) loci. DNA testing can predict puppy colors and identify carriers of recessive color genes.

Coat Genetics

Bull Terrier coat color is controlled by several genes that determine pigment production and distribution. The primary genes include the E (extension) locus, A (agouti) locus, K (dominant black) locus, and B (brown) locus.

DNA color testing is available and can help breeders predict puppy colors and identify carriers of recessive genes. White coloring is due to the extreme piebald gene, while colored varieties carry standard pigmentation patterns including brindle and red..

Rare vs Standard Colors

Rarity in Bull Terrier colors typically reflects recessive genetics rather than desirability. The breed offers 6 color varieties, with standard colors including White, Brindle and White, Red and White, Fawn and White, Tri-color. While unusual colors may be visually striking, they sometimes correlate with health concerns or breeding shortcuts.

A reputable Bull Terrier breeder will never compromise health testing (for Deafness and other conditions) to produce trendy colors. Be skeptical of breeders who market 'rare' colors at prices well above the $1000–$2000 standard range.

Do Bull Terrier Colors Change with Age?

Many Bull Terrier puppies experience some degree of color change as they mature. Puppies may be born darker or lighter than their adult coat. Standard colors (White, Brindle and White, Red and White, Fawn and White, Tri) typically stabilize as the puppy coat transitions to the adult coat between 4 and 12 months of age.

Controversial Colors

In the Bull Terrier world, so-called 'rare' colors can be controversial. The breed standard recognizes colors like White, Brindle and White, Red and White, Fawn and White, Tri, and deviations may involve genes associated with health problems. Breeders who focus on color over health may cut corners on testing for Deafness and Hereditary Nephritis.
