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 Black Norwegian Elkhound was first bred in Norway in the early part of the 19th century as a smaller version of the Grey Norwegian Elkhound. The Black version is a Spitz and is very seldom seen anywhere in world but Norway. He is designed for the same job that the Grey Norwegian Elkhound performed. The difference is that the Black Norwegian is smaller, easier to see in the snow and ice of Norway and smaller than the Grey. It is a hunter, a herder, a guard dog and a watch dog. Because of the temperatures in Norway it was very important to have a hunting dog that was able to deal with the cold, the snow and the heavy fall rains in Norway and Scandinavia. The Black Norwegian Elkhound is a powerful and prideful dog. Much more so than the grey, he is independent and strongminded. It is highly intelligent and is one of the most ancient of breeds. He is more durable and more quarrelsome than his cousin the Grey Norwegian Elkhound or the more familiar Swedish Elkhound.
Ancestors of the Black date back to the first days human kind went hunting around 4000-5000BC. There have been skeletons of dogs very much like the Black Norwegian Elkhound found that dated back to that time period. They hunted and guarded for the Vikings and pulled sleds as well. They hunted deer, moose, badger, elk, mountain lions, bears, wolves, lynx, rabbit and reindeer. They are trackers who hold their quarry at bay by barking until the hunter can find them. Today they serve as loved family pets and guard dogs. In a National Emergency the leader of Norway can call up all the privately-owned elkhounds of any kind and assign them to work in a variety of sledding duties. Within the FCI, the Black Norwegian Elkhound is classified as a primitive Nordic hunting dog.
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.
The Black Norwegian Elkhound is a short compact Spitz with dark eyes and a curly tail. It is the coat that sets this dog apart. It is an all-weather coat suitable for the cold, the snow and the rain of Norway. Ears are pointed and erect while the head is wedged and broad. His head is almost like that of a wolf. Its body is strong and compact. Its coat is coarse, short and double. He has a broad black nose with a straight bridge and with black lips and dark brown oval eyes. His legs and withers are strong boned and powerful with well padded feet to protect it from the freezing temperatures of Scandinavia.
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.
This dog was made for families. He loves children and is not a one person dogs. He gets attached to everyone in the family. However, he is smart and stubborn. He loves to join in with whatever the family is doing but he does it to please himself not his owner. He loves, loves, loves to play and has the stamina to do so all day long. He is agile, bold, independent, strong, curious and loyal. His loyalty can be territorial, and he can become protective of his home and his family. This makes him an excellent watchdog until your friends come to visit and he won’t let them in the house. You need a high fence to keep him safe in your own yard and away from strangers and even guests till he gets to know them.He tends to be dominant and aggressive with other dogs. They also have strong hunting instincts.
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 Black Norwegian Elkhound is a strong and hardy dog, though he is susceptible to some of the problems many breeds face. These include issues with luxating patella, optical entropion, hip dysplasia, hypothyroidism, and Fanconi syndrome. The most serious of these is the Fanconi Syndrome which is an abnormal functioning in the tubules of the kidneys. This can be a life-threatening situation.
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 is an energetic active dog, or she should be. Feed her high nutritious food twice a day. Do not overfeed.
The most potentially troublesome health issue is Fanconi Syndrome. This kidney disorder can impact the of the body’s absorption of electrolytes, water and nutrients. These nutrients include Sodium, Potassium, Glucose, Phosphate, Amino Acids and Phosphate
The Black Norwegian Elkhound loves to play, and they love to work. Exercise is vital, but it must be one of those two things – play or work. Don’t leave him alone to figure it out for himself or you wont like what this intelligent dog decides to do. She needs a large yard, a long walk daily but jogging with you is even better. Make him heel when on leash or he will think he oversees you. These are roaming dogs who will follow a scent anywhere and ignore your commands for her to come to you. They are better off on a leash unless you are in a dog park or a fenced yard.
The Black Norwegian Elkhound is great at all dog athletics, games and sports such as agility, rally obedience, flyball, tracking, herding.
