The Red-Tiger Bulldog is an American dog breed that was developed in 1991.

The breed derives from red-nosed American Bulldogs that were owned and bred by Rev. Scott L. Amos Sr. and his international breeding program “S. Amos American Bulldogs/Free-Style American Bulldogs”. Originally, the breeder's intention was to compose a quality bulldog of distinct color and beauty while maintaining diverse functional working structures and abilities. Additional characteristics that were preserved through breeding were the bulldog’s naturally protective prowess, free-producing sires, free-whelping dams, and natural coursing ability.

The Red-Tiger Bulldog breed is recognized by its principal/parent registrant the “Red-Tiger Bulldog Registry and Archive”, The Canine Bodybuilding Association, the American Canidelogical Kennel Club.

The "Red-Tiger Bulldog" breed was created in 1991 by Rev. Scott L. Amos, Sr. and his son, Scott L. Amos II, in Anderson, Indiana. The Red-Tiger Cani-Bull and the Red-Tiger Brachi-Bull Bulldog varieties were registered in the state of Indiana on March 17, 2010. The Red-Tiger Bulldog’s breed registry and archive received the government’s principal registration with the United States Patent and Trademark Office on January 18, 2011 as “The first Red-Nosed Breed of Bulldog in the history of the world”.

Multiple other bulldog breeds exhibit traces of red-nosed specimens as a less desirable trait within their black-nosed breed standard. The Red-Tiger Bulldog is bred to reproduce dogs of exclusively pheomelanin/amelanotic skin and coat colors of red or reddish-brown brindles.


In the late 1990's, Rev. Amos infused the Red-Tiger Bulldogs with Ca de Bou genetics for out-cross vigor; Ca de Bou genetics include DNA from Mallorquin Bulldogs, Banter Bulldogs, and pure Old Southern White Bulldogs. This complex infusion allowed the Red-Tiger Bulldog strain to attain higher levels of health, refined structure, enhanced endurance, and a more cephalic head and jaw. This infusion also added several benefits to the overall makeup of the Red-Tiger Bulldog which eliminated poor respiratory system problems that had been prominent in many other bulldog breeds.

In the early-to-mid 2000's, Amos and family added Brindle Levitt-mixed bulldog blood obtained from Luis Rojas of Chicago, Illinois. Red-nosed, red-brindle mixed-bred bulldog blood was also added to the Red-Tiger Bulldog's genetic makeup; its source hailed from areas in the southern United States, such as Talladega, Huntsville, and Birmingham Alabama. One Bulldog/Boxer strain that was produced by amateur breeders Mr. and Mrs. Kendrick Swain of Atlanta, Georgia, expanded the genealogical stance of the Red-Tiger Bulldog's lineages.

General Appearance[edit]

The Red-Tiger Bulldog is a strong, mesomorphic, athletic, endurance-endowed, active, working bulldog of great character. It is uniquely colored in a mantle coat design of exclusively red or reddish-brown brindle hues with light-colored eyes. A bulldog of stature, its long legs and free gait give it a natural coursing ability. Tail docking is a must for registration and confirmation exhibition in the United States; ear cropping is also a must for the show ring in the United States. The structure of the bulldog is moderate to formidable and never extreme. The confidence this breed carries in its eyes and bold posture serves as a deterrent to any home, property or personal threat.



Red-Tiger Bulldogs are a modern-day “aesthetically original” and are considered to be a groundbreaking bulldog. Its genetic color composition of red or reddish-brown brindles has never been seen in another bulldog breed. The Red-Tiger Bulldog's coat hair tends to be short, smooth, and glossy overall.


Red-Tiger Bulldogs only come in varying shades of red and reddish brown. Red-Tiger Bulldogs don’t produce specimens with gray/ blue and black coat hair or gray/blue and black skin. The Red-Tiger Bulldog usually has a “mantle” coat that is at least 70% color and no more than 30% white. The Red-Tiger Bulldog also exhibits a “mosaic brindle” pattern wherein two or more variations of brindles strive to express themselves in the same animal. This causes one shade of brindle to inhabit the body and another shade of brindle to cover the inner legs, underbelly, eyebrow, and jaw. Specimens of the “mosaic brindle” coat pattern are the most highly valued.

Show Standards[edit]

Red-Tiger Bulldogs must always have a colored face and head; white ears and small white marks on the ears are tolerated. The dog should be brindle and white with a solid brindle body. A standard brindle head with white blaze and muzzle is preferred but optional. A white collar is preferred, but a break in the collar or no color is acceptable. A white chest is optional, and a small white marking in the brindle body is acceptable. While white on the feet is preferred, white on part of the forelegs/hindlegs is acceptable. Show dogs should exhibit a correct mantle coat design, and be faulted for deviating from such accordingly.

Coat faults[edit]

Common coat faults include:

  • Long hair
  • Less than a full face mask
  • White marks on ears
  • White ears

Disqualifying faults/non-registerable coat faults include:

  • Any color other than red or reddish brown brindle
  • White face
  • Half-white face.


The head of a Red-Tiger Bulldog exhibits great power and rests on top of its muscular neck. The skull is typically flat and moderate to large in size with a very defined stop that is not overly pronounced. As for the facial region, Red-Tiger Bulldogs feature Amelanotic noses of red or reddish brown hues with moderate to wide nostrils. Their ears are cut medium in length except in countries where cropping is illegal. Their cheek muscles are well-developed and produce tight-fitting lips. Their muzzles, jaws, and teeth tend to be very strong, deep-set, and wide. However, they tend to suffer from a slight to moderate underbite.


The keen eyes of a Red-Tiger Bulldog are always light-colored, featuring shades of greens, yellows, hazels, and even blues. Their eyes are round or almond-shaped with close-fitting eyelids that have red /reddish-brown pigmentation. In some cases, Red-Tiger Bulldogs can be born with eyes that do not match in color. This condition is called “skittle eyes” and is considered a very desirable trait. A similarly rare and desirable trait is known as “candy eyed”—this occurs when the Red-Tiger Bulldog has two blue eyes. While nothing is wrong with matching or mixed-matched eyes, it is considered a serious fault when Red-Tiger Bulldogs are born with crossed or non-symmetrical eyes. Non breed-able faults include broken or glass eye’s and albino-pink eyes.


Red-Tiger Bulldogs have a Mesomorphic build making them moderately rectangular in shape and naturally endurance endowed. They have level backs, and the length from the withers to the root of the tail is slightly greater than the height from the withers to the ground. Their chests are deep, reaching down to the elbow, and are a moderate to formidable width with good clearance from the ground. Their ribs tend to be well sprung from the spine, and their sternums are inclined forward. The loins of a Red-Tiger Bulldog should be short, strong, and deeply muscled. Their tails are always docked at 3–5 vertebra (with non-docking exceptions made in countries where docking is illegal). A docked tail must as least cover the anus when laid down in order to cover and protect from external elements and weather. According to the Principal/Parent Registry Amendment[citation needed], Red-Tiger Bulldogs must be docked in order to be registered in the United States as of January 1, 2016. It is considered a fault if the tail is docked too short, the tail is too long, or if the dog has no tail at all.



The Red-Tiger Bulldog's shoulders are moderately to heavily loaded with muscle and have moderate to maximal definition. Their upper arms are of sufficient length and angulation to ensure that the elbows are set under the body. Their forelegs are straight from the elbows to the toes when viewed from either the front or the side.


Their hindquarters are strong and muscular, balanced in proportion with the shoulder. Their stifles are moderate to well-angulated and muscular. Their hock joints are moderately set and their rear pasterns are parallel when viewed from behind while in freestanding position. Their feet tend to be moderately round, hard, padded, and moderate in size with toes that are moderately arched. They have a true and free gait with a springy, powerful drive from the rear.

Size and Weight[edit]

Male Red-Tiger Bulldogs can reach heights of 22-26 inches and weigh between 75-115 pounds. Female Red-Tiger Bulldog can reach heights of 22-25 inches and weigh between 65-105 pounds.

Behavior and Temperament[edit]

The Red-Tiger Bulldog is confident and outgoing, always seeking to please. The breed is trustworthy, mild-mannered, and gentle with children. They are intelligent, discerning, and very protective of their owners and their owner’s property and will guard them even unto death. They can be aloof and intimidating with unannounced strangers, as their watchdog prowess is expressed, but will calm right down with the reassurance of their master. The Red-Tiger Bulldog is always loyal to its family although it is imperative that the Red-Tiger Bulldog understands that human pack members are all superior to them. They get along well with familiar dogs and animals. However, their Alpha Spirit and domineering attitude may lead to continuous bidding for ordinal ranking with specimens of the same sex, especially in males. Their high prey drive leads them to chase rodents and vermin naturally. Therefore, early socialization and obedience training is needed to stifle the possibility of aggression with unfamiliar, same-sex dogs and small, vermin-like animals.

Care and Activity[edit]

Red-Tiger Bulldogs do well in city and rural areas, but regular play time and exercise is a must. They are very active dogs and require a physical outlet. Minimal grooming is required with this short slick-coated breed; regular brushing and washing as needed will keep them show-worthy. Regular walks will help keep their nails at a healthy length. Irregular feeding patterns, overfeeding, or lack of proper nutrition can result in "down pasterns" or knuckling over in the forelegs. Ergo, it is very important that Red-Tiger Bulldogs receive a consistent puppy diet during their first year of growth.


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 playtime 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 verbal praise tend to yield a positive response. Red-Tiger Bulldogs also have a great memory and retain lessons quickly, making them very trainable dogs.

Show Faults[edit]

Any departure from the foregoing points should be considered a fault in showing competitions. The seriousness with which each fault should be regarded is in exact proportion to its degree and its effect upon the health and welfare of the dog.

However, the following weaknesses should be particularly penalized:

  • Lack of true bulldog characteristics
  • Lack of balance, i.e. overexaggeration of any points
  • Sluggish or unsound movement
  • Faulty mouth
  • Long coat hair
  • Closed nostrils

Non-breedable Faults[edit]

Male animals should have two apparently normal testicles fully descended into the scrotum. (Monorchid or cryptorchid individuals are non-breedable.)
