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.
It was in 1802 that George Hall arrived in New South Wales, establishing 2 cattle stations. He had a problem – getting his thousands of cattle to the Sydney markets. He began looking at the prospect of a droving dog and imported a number of dogs of which a blue mottled dog emerged.
The dogs were crossed with dingoes and by 1840 the Halls Heelers were used by the Halls. However with the death of one of the Halls, their cattle stations went to action and the dogs, the Halls Heelers became available.
The dogs attracted attention, and the term ‘Australian Cattle Dog’ was adopted. The name referred to those dogs coming from Thomas Hall's ‘Heelers’. There have been many arguments about the origin of the breed, but the red or blue offspring known as Hall's Heelers were proven cattle drovers, and with further breeding experiments which included the Australian Kelpie, dingoes and the Dalmation, by 1893, the tough, robust working breed known as the Blue Heeler or the Australian Cattle Dog came about.
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.
Blue Heelers are medium-sized, sturdy, compact dogs who are somewhat longer than tall. The female Blue Heeler measures roughly 43–48cm at the withers, while the male measures about 46–51cm. If your Blue Heeler is in tip top condition, he’ll weigh about 15 to 22 kilograms. They are muscular with pointed, erect ears, dark eyes and long tails which are mostly hanging downwards. Their dense coats are blue- or red speckled and sometimes with tan markings.
The Blue Heeler is a ball of energy and he is clever too. You won’t find him sitting around for too long, and if there is sign of a walk or a ball game, he’s in! He is an independent dog, and although he makes a wonderful family pet, he tends to attach himself to that one special person in his life. He is a natural watchdog and protector of his human family.
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.
Training and socializing of your Blue Heeler will ensure that your dog does what you want him to. The Blue Heeler is an intelligent, responsive dog and training can benefit him, turning him into an outstanding family pet, good with children and other pets in the home.
He is a playful, affectionate pet who doesn’t take easily to strangers, and this is what makes him such an excellent guard dog.
Your Blue Heeler is not an apartment dog as he requires a lot of exercise, and cooping him indoors for too long with nothing to do can lead to destructive behavior.
Head-strong, independent and robust, your Blue Heeler will need a firm owner who is boss. Add to the firm owner a lot of love and care, and you’ll have a devoted friend.
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.
Australian cattle dogs are healthy and can live up to 15 years of age, but even so there are some genetic conditions that you will need to be aware of following
Eye issues which includes progressive retinal atrophy – this disease is an inherited disease of the retina of the eye where the rod cells are destined to die. Fortunately it is not painful for the dog. There are different types of inherited retinal degenerative diseases in dogs but going into detail with them is beyond the scope of this article. For more information you can chat to your vet.
Recessive piebald elleles - the Blue Heeler has recessive piebald alleles which can produce white in the skin and coat and which is linked to congenital hereditary deafness.
Giant breeds like the American Mastiff are known for growing rapidly as a puppy and therefore proper feeding and nutrition is essential. The slower your American Mastiff grows, the better. 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.
Unlike the way he looks, the American Mastiff is not a couch potato, but neither are they a high energy, exercise machine. They do well living in apartments or homes, with or without a fenced in yard. They need a long walk every day. They need mental stimulation through exercise and games. Make sure they learn to love to play so that they don’t become lazy as they age.
Remember that your Blue Heeler was once a full time cattle dog where he used to become totally and utterly exhausted from herding cattle. This is what he loved – the activity. If you have a Blue Heeler, you will need to provide him with plenty of exercise.
If you live on a farm, your Blue Heeler will be in his element because he can run, walk and swim to his heart’s content. If you keep your Blue Heeler in your back garden, you will need to provide him with ball games, rope games, long walks, running on a leash as you cycle and other activities.
Your Blue Heeler has a short, weather-resistant double coat. He’s not a heavy shedder, but he will have his share of seasonal shedding, so it’s a good idea to get into the habit of brushing him at least twice a week. This will get rid of all those loose hairs and keep his skin healthy by getting the blood flowing and distributing his natural oils.
Giving the best dog food for your Blue Heeler will come from either your home made food or a top quality commercially manufactured dog food. He is such a high energy dog, that your veterinarian can advise you on a dog food specially designed for high energy breeds.
These foods are well balanced and are enriched with amino acids and vitamins, promoting healthy bones and joints. Remember to include some raw meat into your dog’s diet and to ensure a constant source of cool, fresh water.
Ensure your Blue Heeler’s ongoing health by paying attention to ears, nails and teeth.
