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 Griffon Nivernais is a working breed dog originating in France and used as a hunting dog because of his exceptional scent skills and his alertness with hunting.
The idea was to develop a dog that looked much like the hunting dogs of the Middle Ages. French noblemen kept these dogs but the breed disappeared somewhat after the French Revolution, being restored again in 1925.
The restoration of the breed was done based on the Grand Griffon Vendeen but other breeds were also used such as the Otter- and Foxhounds. The breed has yet to receive official recognition by the AKC but it is recognized by both the FCI and the UKC.
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.
As a medium sized dog, the Griffon Nivernais stands at 55 to 62cm in height and weighs between about 22 and 25kg.
He is recognized easily by his distinctive rough or shaggy coat which is a grey with fawn around the muzzle and legs. Other colors can be black and fawn. Sometimes this blend of colors gives him a grizzled look in appearance.
He is also noted for the hairy eyebrows, a beard and mustache. He has dark brown eyes, black nose, long floppy ears and a tail that is held upright and with a slight curve. He is a muscular dog with a deep chest and a slight arch in the back.
Stubborn, courageous and independent, the Griffon Nivernais is a hunting dog with amazing scenting abilities. He is a dog used to working in a pack with other dogs so he tolerates other dogs well. He is a friendly dog, getting on well with children as well.
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.
Your Griffon Nivernais is a sociable, stubborn, independent dog who loves to be around his human family members.
Socialization and training will do him good and round him off, making him obedient and responsive to your commands. He isn't an aggressive dog, but is even tempered and confident.

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.
The typical lifespan for your Griffon Nivernais is 10 to 14 years. Even though you're highly unlikely to spend much time with him at the vet, there are one or two common dog illnesses worth knowing about -
It is the fate of many dogs with floppy ears that they are prone to developing ear infections. You may notice him shaking his head canine, his ears may be red and there could even be a discharge.Get him to the vet as ear infections can be promptly treated with a course of medication.
Remember to have your Griffon Nivernais puppy vaccinated at 6 weeks of age. Puppies are vulnerable to horrible diseases which can sap the very life from them. These diseases are distemper, canine hepatitis, parvovirus as well as rabies. The puppy’s first vaccinations should be at 6 weeks of age followed by a second vaccination 2 to 4 weeks later.
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.
This breed needs to be walked daily, and he needs a large space to run and play. Take him on walks, to the park, or give him a good game with ropes and balls.
In spite of his long, shaggy coat, the Griffon Nevernais doesn't need any special grooming and his shaggy coat will require brushing twice a week to remove loose hairs. When you brush him, you can also check for fleas and ticks.You get special flea combs for this. You can speak to your vet about recommendations too.
Because his coat is of a harsh texture it doesn't tangle or matt. Bathing will only be necessary when he becomes super dirty as too much bathing removes natural oils. He will need to have his nails trimmed if they don't wear down naturally, and he will also need to have his ears cleaned to keep them free of wax and dirt and to prevent ear infections.
Brush his teeth 2 or 3 times a week will also help towards preventing dental disease.
He is a high energy dog so he will need to get top quality food. You can feed him the best commercially manufactured food but its to his advantage to include some home-made food too such as cooked chicken, brown rice and vegetables. He'll also need some raw meat from time to time and a constant supply of fresh, cool water.
