The Red-Tiger Bulldog only comes in pheomelanin / amelanistic skin and coat pigment colors of red and reddish brown. Red-Tiger Bulldogs do not produce specimens with gray/ blue or black coat hair; neither do Red-Tiger Bulldogs produce gray/blue or black skin.

The Red-Tiger Bulldog should have a “mantle” coat design, of at least 70% color and no more than 30% white. The color shall be brindle and white with a solid brindle body suit/blanket extending over the body; A brindle skull with white muzzle; a white blaze is preferred, but optional; A white collar is preferred BUT a break in the collar or no color is expectable; A white chest is optional; White on the feet is preferred, white on part of the forelegs and hind legs is acceptable; A small white marking in the brindle body suit/blanket is acceptable. The Red-Tiger Bulldog only comes in varying shades of red or reddish brown-brindle, including, red brindle, chocolate brindle, liver brindle and cinnamon-brindle. The Red-Tiger Bulldog is also known to exhibit a “mosaic brindle” pattern within its phenotype, where two or more variations of brindles strive to express themselves in the same animal, causing one shade of brindle to inhabit the body suit/ blanket and yet another shade of brindle to cover the inner legs, underbelly and jaw. Specimens of the red-brindle variation of the “mosaic brindle” coat pattern are the most highly valued.

The RTB’ neck, should be massive and imposing, “never” thin or elegant. The RTB’s neck is very powerfully built and should display pound for pound “the physical appearance of harboring enormous strength”, the neck should be widest at its base, even to the point of being as wide as the rear of the occiput (rear of the head)

The back” should be very firm and solid beneath the hide; it should exhibit moderate to ample definition, the Top line should be level, while allowing a slight downgrade near the withers when young. A very moderate roach is expectable but not encouraged.

The shoulder / upper- arm region of a RTB is worn like a badge of honor, for it is one of the RTB’s most imposing and enduring attributes. The shoulder of a RTB, like the pads of a NFL running back leads the dog into and through the fray of opposition with power, while serving as protection against any excessive contact. The shoulder should always be one of the more defined / ripped attributes of a RTB’s muscle anatomy. The shoulder must appear conditioned, and massive, it should display each of the three parts of the triceps muscle during movement and the deltoids should appear as two moderate to prominent cords traveling from the triceps up into the wither and neck region.

The chest of a RTB should appear to be carried proudly and give the impression of a gladiators shield or breastplate leading him into battle. When sitting, the pectoral muscles should protrude forward revealing ample to extreme levels of striation incased by the outward rounded deltoid/ and triceps muscles of the shoulders. When standing this same chest muscle should appear heavily padded and should be attached to the breast plate/sternum and only allow a void spot appearing as two small sunken pockets residing one per side of the breast bone.

The forearm should appear heavily padded with muscle. The forearm although not having massive muscle, should still display moderate depth and separation between the many muscle groups of this area. The forearm should be tight. It should be very firm to the touch do to the padded muscle aside from the hardness of the bone. The forearm should reveal definition when standing, when seated and must exhibit burst of striation during movement.

The “hind quarter” consists of the most explosive muscle groups in a RTB’s anatomy. The rear end of a RTB’s anatomy is its principle driving force and should physically exemplify breath taking levels of energy and explosive power. Each member should be very round both inside and out when standing. The hind quarter should appear charged and ready to explode into action. When in motion, the hind quarter should exhibit several points of definition and appear to propel the animal forward with an extreme level of controlled thrust.


The RTB is trustworthy and discerning, with a desire to under-gird his master. The confidence this breed carries in its eyes and the bold please itowcases, serves as a deterrent to any home/ property or personal threat. The Red-Tiger Bulldog is always loyal to its family but may not be welcoming to un-escorted house guest. They can be domineering and aggressive to strange dogs and animals if not imprinted / encouraged to do so from a young age. They have a strong prey drive. Early socialization / obedience training is advised to stifle the possibility of aggression with strange dogs and small vermin like animals. They get along well with familiar dogs and animals. The Red-Tiger Bulldog needs a firm, consistent and confident owner. This Breed is intelligent and eager to please, yet can be stubborn and push for play time during training sessions. A brisk walk or short play break prior to training sessions tends to burn enough energy to curb this issue. Mild corrections and ample amounts of verbal praise tend to produce a positive response. Overly aggressive physical corrections or dominance can do irreversible physiological damage. Red-Tiger Bulldogs have a great memory and retain lessons quickly. It is imperative that the Red-Tiger Bulldog understands that the human pack members are all superior to them in the pack order. The Red-Tiger Bulldog is outgoing and mild mannered, gentle and submissive to children. They can be aloof with unannounced strangers as their watchdog prowess is expressed, but will calm right down with the reassurance of their master. Red-Tiger Bulldogs are very protective of their owners and their owner’s property and will be loyal to them, even giving their own life.

The Red-Tiger Bulldog was created by Rev. Scott L. Amos, Sr. and his son, Scott Amos II in the central Indiana region of the United States, beginning in 1991. The Red-Tiger Bulldog was developed from a foundation of red-nosed American Bulldogs owned and produced by Rev. Scott L. Amos, also known as “Scott Free” and his then international breeding program "Amos American Bulldogs" and "Free-Style American Bulldogs". The Red-Tiger Bulldog’s Breed, Breed Registry and Archive received the government’s principle registration (Serial #85002578) with the United States Patent and Trademark Office on January 1, 2011 as “The First Red-Nosed (Breed) of Bulldog in the history of the world”. While most other bulldog breeds exhibit traces of red-nosed specimens as a less desirable traits within their black nosed breed standard. The Amos’s have developed the Red-Tiger Bulldog to reproduce exclusively dogs of pheomelanin / amelanistic skin and coat colors of red or reddish brown in a brindle pattern. The word “Tiger” in the breeds name is derived from the brindle tiger like striping in the Red-Tigers coat pattern. The ”Red” portion of the breeds name is descriptive of the red or reddish brown skin and coat color, while the word “Bulldog” in their name characterizes the heritage of the breed’s ancestral genetic composition.

In the late 90’s Rev. Amos infused Ca de Bou – Mallorquin bulldogs, Banter Bulldog and pure Old Southern White Bulldog genetics for out-cross vigor; This complex infusion allowed the Red-Tiger Bulldog strain to attain higher levels of health, refined structure; (allowing enhanced endurance), and a more cephalic head, Jaw and respiratory system; (which allowed clean breathing), rather than the historically poor respiratory system existing in many other bulldog breeds, which stemmed from the more common brachycephalic jaw and respiratory that bulldogs in general were founded from.

In the mid 2000's The Amos's added Levitt-mixed Bulldog blood and mixed-bred bulldog blood from the southern US, such as Talladega, Huntsville, Birmingham, Alabama and one Bulldog/ Boxer Strain in particularly produced by Hobbyist breeders Mr. and Mrs. Kendrick Swain of Atlanta GA… to expand the genealogical stance of the RTB's lineages.

Although, inevitable evolution is at hand, the Founding and developmental dispensations of this Breed have been surpassed and the RTB is now a beautiful reality rooted in the History and archives of America.
