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.
Known also as the Swedish Elkhound or Swedish Moosehound, the Jämthund is a dog which hails from Sweden, and more specifically from a region known as Jamtland.
The dog received official recognition in 1946 as a dog breed from the Swedish Kennel Club. DNA testing tell us that these dogs originated from the crossing of a wolf, being described as a ‘Spitz-type dog’.
They were once used to pull sleds, and its why today he is an energetic dog, requiring a good dose of exercise and activities from his owners. The UKC accepted the dog as an official breed in 2006.
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.
Described as a medium to large sized dog, the Jamthund stands at about 52 – 65cm in height, both males and females, and they weigh in at about 25 to 35 kilograms.
They have that typical Spitz-dog tail which curls over the back of the dog. When relaxed the tail hangs straight down. He has erect ears with a longish muzzle, much like a wolf, and his double coat lies fairly close to the body while on certain areas of the body, such as around the neck and tail, it is longer.
The color of his coat is usually light or dark grey with some cream marking around the muzzle, eyes, legs and paws. This fairly large, Spitz-type dog is certainly an attractive dog that while looking similar to a wolf shares some physical features with the Norwegian Elkhound.
Capable of being a splendid family pet, the Jamthund is an affectionate, loyal dog with his human family, although it is true that some of him hankers back to his hunting days.
He is an intelligent, amicable dog, and therefore training and socializing him is easy as he wants to please.
He is very energetic and won't be content with a life curled up indoors. He wants to be busy and involved with all your activities such as walks, hikes and swimming. He has a thick coat and he loves wintry weather, so the cold won’t stop him from wanting a long walk every day.
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.
Loving the company of his human family, the Jamthund gets lonely, bored and frustrated if he is put into the backyard as a watchdog and left. When he becomes naughty it is because he is trying to tell you that he wants to be part of your life.
The Jämthund has excellent hunting skills and with his great intelligence too and his ability to learn easily, he makes a popular pet. He also has other attractive characteristics such as being brave and calm.
He forms a deep bond with his human family and his gentle nature makes him a favorite playmate of children too. They make good guard dogs as they are alert and protective of their human family.
Not only has the Jamthund got many positive characteristics to his name, he is an attractive dog too, and once you've brought one into your home you'll realize what a wonderful dimension it brings into your home and your life.
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.
While the Jämthund is a healthy dog breed and won't cost you much in veterinary bills when it comes to illness, there are some common dog illnesses that are worth knowing about so you can respond in time to his need.
Unfortunately this is a joint problem that can affect even young dogs. The hip joint hasn't formed properly and it can lead to the development of painful arthritis. It can be a debilitating disease for your dog and you will need to see your vet.
This may seem like a trivial kind of dog illness but in fact it can lead to a lot of frustration, pain, anguish and discomfort for your pet. Signs of a skin allergy can include red, inflamed skin, itchiness, pain and oozing sores where your pet licks away miserably at the affected areas.
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.
Your Jamthund is a high energy dog and because of his background of hunting and pulling sleds, he loves wide open spaces where he can run. He essentially suits country life and it wouldn't be wise to confine this energetic dog to a small home.
Brushing the thick coat twice a week will keep it in top condition.Keep his nails trimmed and also keep an eye on his teeth. Find out how to make use of canine toothbrush and toothpaste to keep his teeth clean and free of plaque.
Such a high energy dog requires the very best food packed full of vitamins and minerals. Look for the best commercially manufactured food there is and add in some wholesome home-made food from time to time such as cooked chicken, rice and vegetables as well as some raw meat occasionally. He must have a constant supply of fresh, cool water.
