American Mastiff is originated from United States but German Coolie is originated from Australia. American Mastiff may grow 31 cm / 13 inches higher than German Coolie. American Mastiff may weigh 66 kg / 146 pounds more than German Coolie. American Mastiff may live 6 years less than German Coolie. Both American Mastiff and German Coolie has almost same litter size. Both American Mastiff and German Coolie requires Low Maintenance.
The history of the American Mastiff is entirely tied to the old European Mastiffs but in particular the English Mastiff. The developers of the American Mastiff crossed the English Mastiff with the Anatolian Mastiff at the Ohio kennel, Flying W Farms. The founder of this breed is Fredricka Wagner. Because of this the English Mastiff and the American Mastiff look very much alike. The difference between the two is that the American Mastiff was bred to have less health concerns than the English Mastiff and without the drooling. In 2000 the CKC acknowledged that the American Mastiff and the English Mastiff were separate breeds.
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).
This crossing of the English Mastiff and the Anatolian Mastiff resulted in a Mastiff with a much drier, less drooling mouth than the other Mastiffs. This is a giant, massive dog – powerful and muscular. With a wide head that is rectangular rather than square. Their eyes are dark amber, and their ears are high on their head and rounded. With a medium size muzzle, black mask and heavy head, the American Mastiff is a handsome dog.
Their chest is broad, deep with ribs that extended backward. He has strong legs that are parallel and wide set. He also has a long tail. Puppies of the American Mastiff are born almost black and as they grow their coat color lightens. In addition, it is important that they have a wrinkled forehead as well and a scissors bite is preferred.
With their strong ancestry among the family of collies and herders, the German Coolie shares the look of collies and shepherds. Even though they differ from region to region and there is no actual standard, they are medium sized dogs with blue or brown eyes or even one of each. The ears are folded over on top when relaxed but they are rigid and straight when he is more alert. The nose is either chocolate or red depending on the color of their coat.
They can have either a long, medium or short coat but most owners want the short coat that is smooth as well. The coat can be one color – red/chocolate or black; Bi – red/white or black/white; Tri – solid black or red with white and brown; Tri merle -merle with white and brown; Merle – red merles and blue merles. Regardless of color, the German Coolie has the look of a collie or German Shepherd.
A love of children and devotion to his pack (family) is bred into the American Mastiff. He is non-aggressive unless you threaten his family or his children. Then he becomes courageous, protective and defensive. This is a gentle giant most of the time, however due to size and the need for strong leadership, the American Mastiff should be socialized and trained early. If they are socialized and trained they will be calm, gentle dogs. They will remain protective and alert, but they will be friendly with strangers. They love to please their people and being highly intelligent they learn fast.

American Mastiffs seem to have fewer health issues than other larger giant breed dogs. However, they can experience allergies as many large, wrinkled dogs do. They also might have a tendency toward eye issues, hip dysplasia, cancer and heart disease. Bloat might be the most life-threatening issue many American Mastiffs experience.
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

Make sure your puppies get enough phosphorous and calcium in their high calorie diet. Free feeding is not recommended. Feed puppies up to 4 small meals per day and feed adults twice a day.
As previously mentioned this breed is a fairly healthy one, There, are however, certain evaluations you should do with your American Mastiff puppy to be sure she is in good health. These tests would include an elbow and hip evaluation to check for dysplasia. He should have an ophthalmologist and cardiologist examine him as well. Most American Mastiffs will not have any problems, but these evaluations will help to prepare you if they do. The wrinkles in your dogs; face, around the eyes and muzzle must be kept clean as they can become infected if you don’t.
