Thanks to John D. Johnson from Summerville, Georgia the breed is still with us today. He gathered the best dogs he could find throughout the rural South and bred them back into popularity among his family and other rural families. His father bred the American Bulldog before John did and they have bred them longer than any other in any part of the world. His dogs were regularly used for tracking, hunting, guarding, watchdog and weight pulling. At some point Alan Scott joined Johnson breeding other bulldogs to Johnson's and forming the Standard American Bulldog.
The American Bulldog/ is popular today as a family pet and companion as well as a working dog.
The German Coolie is misnamed as it is an Australian bred dog and often called the Australian Koolie or Coolie. This Australian breed is more often just called a Coolie. The breed is a typical herding breed and a working dog that needs a job all the time. They have been a favorite of Australians since the late 1800’s when local dogs were bred with British working dogs.
Although all Coolie’s are not the same. Within the breed there is a lot of variation. This is because the Coolie was bred individually for different regions in Australia. In a very different writing the Koolie Club of Australia does not define the Coolie breed on confirmation as all other purebred dogs are defined. Instead the Coolie is defined by ability to work. In light of this most Coolie breeders state that the Coolie is a breed and the variations you see among regions are types within the breed.
As a herding dog, the Coolie brought a lot of skill to the Australian farmers and sheep herders. The Coolie will round up the sheep and bring them back to their enclosure at the shepherd’s command. They are upright, silent, working dogs. Not only do they herd sheep they are important at sheering to “cut out” the sheep or assist in the close quarters of lambing.
In Queensland North and New South Wales, the Coolie is medium boned, tall and agile ready to herd cattle over a long stretch of miles. In the Snowy Mountains of New South Wales and the Hunter Valley Region, the Coolie is shorter and thicker in order to be able to get cattle that are lying low out from the gullies and dense bush. The Coolies found in Victoria are the smallest of all.
No matter where they live and work, the Coolie is bred to help the workers there, the farmers, the stockman, and the grazier. All Coolies are adaptable and very agile. They all have a strong willfulness to accomplish what they are asked to do. The ancestors of these various Coolie was the British Collie – a smooth coated, blue merle. This Collie was crossed with the Black and Tan Collie from the Scottish Highlands. It is believed that these are the same Collie breeds that came to Australia to create the Heeler.
The name may come from the German immigrants working in South Australia and unable to pronounce Collie incorrectly they called the dogs German Coolies. There is also a fraction of German breeders who believe that the German Tiger dog was brought to Australia in the 18th century and then when the Collies came they were bred together. Many Coolie breeders have records showing that the breed has been in Australia for at least 160 years. It is also believed that the Border Collie and Kelpie (Blue Heeler) were mixed into the breed at sometime as well.
No bench standard exists for the German Coolie even though there is the Koolie Club of Australia. The mission of the club is to protect, preserve and promote the breed. The Australian Sporting Register was recognizing the Coolies in 2004. They are eligible to participate in the Australian National Kennel Council sanctioned sporting trials. They participate in Queensland, New South Wales and Victoria through the individual states sporting register. Here they participate in herding, jumping, obedience, agility and tracking.
Several other recognitions as a herding breed soon followed. The Australian Shepherd Club of America, the American Herding Breed Association, were followed by recognition from others as well. They are not recognized by the American Kennel Club (AKC).

Though generally healthy, the American Bulldog is prone to a few problems.
This is a serious issue in many breeds of dogs and is especially prevalent with the American Bull Dog. This may seem ironic in such a short legged dog but it is unfortunately very common. It is a genetic disorder that causes the bones in the joint to separate and causes the dog much pain and lameness.
Due to skin folds you need to be care and watch for irritation and infection in the folds. They are also prone to ear infections.
The American Bulldog is prone to overeating and all the health issues that presents. With short legs and a genetic predisposition to arthritis and hip dysplasia, obesity is a real health risk for your bulldog.
This is a relatively healthy breed without many genetic disorders found in purebreds due to the 160 years they have spent fairly isolated and allowing natural selection to take its course.
In Merle dogs there can be deafness and/or blindness. If you breed a solid to a merle you can eliminate that.
These are not inherited but rather acquired due to the immense amount of jumping and running.
Rare but it does occur and can be fatal if not treated
