Bullmastiff Colors: A Guide to the Different Variations

The Bullmastiff is a breed known for its distinctive coat colors, which can vary from red to fawn to brindle. In fact, the breed standard recognizes four main colors: red, fawn, brindle, and blue.

Red Bullmastiffs have a rich, deep red coat that can range in intensity from a light golden red to a dark mahogany. This color is the result of a specific genetic combination that affects the production of the eumelanin pigment.

Fawn Bullmastiffs, on the other hand, have a lighter, more golden coat that can range in shade from a pale cream to a dark fawn. This color is often described as having a warm, honey-like tone.

Brindle Bullmastiffs have a distinctive striped pattern, with a mix of black and fawn stripes that create a mottled effect. This color is the result of a specific genetic combination that affects the interaction between the eumelanin and phaeomelanin pigments.

Blue Bullmastiffs have a rare and beautiful gray-blue coat that can range in shade from a pale slate to a dark steel blue. This color is the result of a specific genetic combination that affects the production of the eumelanin pigment.

Bullmastiffs can have various markings and patterns aside from the brindle that is commonly seen in the breed.

The American Kennel Club (AKC) recognizes white hair sprinkled throughout the coat or a white marking on the chest, although these markings are not considered a breed standard.

White markings can vary in size and shape, and they look particularly striking on red-colored Bullmastiffs.

For fawn-colored Bullmastiffs, the white marking on the chest may blend into the rest of the dog's light-colored coat.

Bullmastiffs can have a combination of black markings (the facial mask) and white markings on their chests.

You can also find Bullmastiffs with a brindled coat, white markings on their chest, along with a black face mask.

According to the AKC, black masks with white markings are recognized, but not considered a standard marking for the Bullmastiff.

Extensive white markings are considered undesirable and can be a disqualification in the show ring, as the breed standard prefers a solid body color with the appropriate mask.
