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.
Developed in Great Britain, the Harrier is another hunting dog – a hound that primarily hunts hares and small prey. The breed itself is medium sized - smaller than an English Foxhound and larger than a Beagle. Although the definitive origins of the Harrier are not set, it is believed that he is a cross of the Basset Hound, Talbot Hound and Bloodhound. Others believe the breed is a cross of the Greyhound and the English Foxhound. The Harrier looks like a smaller version of the English Foxhound.
The Harrier is a pack dog and in 1260, Sir Elias de Midhope established the first pack in England. From there the breed spread to Wales and Western England, most used in Ireland where they hunt fox as well as hares. However, hunting hares is the specialty of the breed and even gave the breed its name. In 1885 they were recognized by the American Kennel Club in the Hound Group. Yet despite this and despite the number of Harriers working in England, they are not recognized by 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.
The Harrier is a typical hound dog much like the English Foxhound. The breed is a little smaller than the Foxhound but is muscular and large boned like his cousin. They have short hard hair that sheds and ears that hang. The Harrier is a large boned breed built for strength and stamina in the race with hares. They have broad skulls, strong muzzles, with hazel or brown eyes. They also have a black, wide nose and a high, medium length tail.
They say he has a ‘courtly grin’ on an expressive face. Being pack dogs, they must be sturdy, able to cover any type of terrain, for as long as the hare runs. It is critical that their scenting and running tools are exceptional. He is blue or yellow-pied. His feet are cat like and the chest is dropped low. He is an extremely well-proportioned dog
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.
Yes, they are good with children but are very rambunctious and should be supervised with young children.
Scenting ability and wonderful personality
This breed is very adaptable as long as it gets enough exercise. He can live in the country or she can live in the city with an outlet for exercise.
Smart but stubborn at times. Therefore, his learning ability is moderate.
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.
It seems the only real health issue other than hunting accidents or foot and toe incidents due to hunting.is:
This abnormality in the hip socket can cause arthritis and lameness that is very painful. This is the most severe form. The Harrier can have a milder form that does not progress to this level. Hip dysplasia has a genetic component, but the environment plays a role as well and active hunting dogs are especially prone to this.
Floppy ears that hang down are always susceptible to ear infections. Check them often and clean them at least weekly.
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.
Feed a high nutrition puppy food dry food made for an energetic breed. Feed 3 times a day ½-3/4 cup each time.
Again feed a high nutrition adult food for an active breed. Feed twice a day 1-11/2 cups each time.
Outstanding health unless in a hunting accident.
The Harrier is an energetic, hunting breed that needs a lot of exercise on a daily basis. Long walks and jogging or running is good for the Harrier. If they are not working, hunting dogs they need more exercise. A fenced yard for playing is good. If this intense breed does not get enough exercise and mental stimulation, he needs there could be issues with destructive behavior and obesity. Flyball, tracking, agility, coursing, rally and hunting are great activities for this breed of dog. In addition, they are pack animals and do better in a family that has more than one dog.
