NICK-OR-OTHER NAME

ORIGINAL STANDARD:  NKC

 

 

The goals and purposes of this breed standard include: to furnish guidelines for breeders who wish to maintain the quality of their breed and to improve it. Any departure from the following should be considered a fault, and the seriousness with which the fault should be regarded should be in exact proportion to its degree and its effect upon the health and welfare of the dog and his working ability.

 

1 DESCRIPTION 

2 official versions of the breed:

a) The “Classic”, also called “Bully” JOHNSON American Bulldog bred by John D. Johnson is crossbreed between the old Johnson breed and a northern English bulldog. Distinct for its wide chest, boxy head, and undershot bite. These dogs due to their size and heavy frame are less energetic.

b) The “Standard” or “performance” type SCOTT American Bulldog Bred by Alan Scott is acrossbreed between the early Johnson American Bulldog and non-Johnson bulldogs. Distinct for its reverse scissors bite, slightly dropped jaws, and narrow muzzle and head. As compared to the Johnson bulldog, its smaller frame and lighter weight enables it to engage in more physical activities, making it the ideal companion for dog owners with an active lifestyle.

c) The "Hybrid" type. A cross between the 2 lines (No official standard nor show ring), they are often shown in one of the 2 above categories, following their phenotype. 

 

It can be observed that the actual Classic American Bulldog is often a cross between the 2 lines and has less head type that the original Classic Johnson Bulldog.
 

2 HISTORICAL SUMMARY 

 

By the end of World War II, John D. Johnson and his father saved the American Bulldog from near extinction by looking for ideal breeding specimens from the south. As the Johnson Bulldog breed slowly became established, Alan Scott joined Johnson to further revive the breed. Later on, as American Bulldog breeding practices progressed, Alan Scott developed a breed distinct from Johnson’s, which consequently led to the development of two different lines: the Johnson and the Scott American Bulldog.

3 GENERAL APPEARANCE:

Of all the Bulldog breeds, The American Bulldog is certainly one of the most elegant. It is an athletic, temperamentally sound medium to large sized dog that possesses great strength, agility and confidence. The expression should reflect intelligence and alertness.

4 TEMPERAMENT 

 

American Bulldogs are friendly, happy lovable dogs with an assertiveness and confidence that never gets out of control. Though initially stubborn in training, they soon respond to their masters’ commands and prove to be endlessly faithful companions who are perfectly in tune with human emotions. They may be distant with strangers but their sharp instincts allow them to quickly assess any situation. The American Bulldog should be sociable with other dogs.
