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.
Teddy Roosevelt Terriers (Teddy, American Teddy) are American hunting terriers related to American Rat Terriers and a host of other working, farm, hunting dogs initially brought by working-class immigrants from England and Europe. Largely due to the working nature of these dogs early the cross breeding was to reinforce useful traits like a superior ability to scent prey. It also bequeathed the breed with superior intelligence. While they take a while to warm up to new people, to their human family they like to be close all the time, and are eager to be with them and please them. Teddy's share their early history with American Rat Terriers, Fox Paulistinha, Tenterfield Terrier and Beagles. They also are related to Feist (dog), and Turnspit dogs, English White Terrier and Wry-legged terrier (all now extinct), as well as Bull, Smooth Fox, Manchester Terriers with Beagles, Italian Greyhound and Whippets in the mix.
Only since 1996 have Teddy Roosevelt Terriers had standards set for the breed. The major difference between Teddys and the related American Rat Terrier is Teddys are closer to the ground (bench-legged), have greater bone density and more muscle. Teddys are medium to small sized. It was in the mid 1990's that the effort began to breed only the shorter legged phenotype into the Teddy lineage and allow the rat Terrier to be the longer legged variety. The UKC (United Kennel Club) and AKC (American Kennel Club) both recognize Teddys, the UKC since 1999.
The Rat Terrier Club of America separated the long legged and short legged varieties, the short legged ones were named in honor of President Theodore Roosevelt. It is rather interesting that President Theodore Roosevelt, while being very fond of his family dogs did not own any Rat Terriers, and did not help develop the breed that bears his name. He mentions dogs in several of his letters, Skip who rode with the president on his horse while hunting and belonged to a friend, Scamp who lived with the Roosevelt's in the White House and hunted and caught rats and their dog Jack.
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.
Teddy Roosevelt Terriers are hunting terriers that are short legged, well muscled and very active. They have proportionate wide, sightly rounded heads cuneus (wedge) shaped on which the V shaped ears are set on the outside edge. Their ears may be button or erect, and breed standards prefer a docked tail, but it is not necessary. Ideally Teddy's have length/height ratio is 10/7 or 10/8. The Teddy Roosevelt Terriers coats may be solid white, other colors with patches and markings. Their coats are short and rough. Because they are working dogs, what is termed as “honorable” scars from work are not deducted from the dogs points. If the dog is not proportionate to breed standards (for example long legs or square body) it may be disqualified, but exaggerations and faults are marked only is in as much as it interferes with the ability to work. They are very pleasant looking and have a lively manner.
Teddy Roosevelt Terriers are happy when they are the constant companion of their owner(s) and will shadow their master all day. Temperamentally they love to play, do well in obedience training and are territorial and protective and are exceptional watch dogs. Of course, they were bred as hunting dogs and have hunting instincts, a greater than median prey drive and will chase anything they consider prey such as rabbits, squirrels, birds, stray cats, (and if not trained poultry), as a working dog training is really important. With a heightened sense of smell and superior prey drive, Teddy's have been observed to follow and dig along mole trails (adding further damage to what the moles may have already inflicted), as well as ferret out edible mushrooms.
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.
1.Children friendliness yes Teddy's love to play and enjoy children. Enjoys spending time with family and interacting with their human family taking part in the everyday routines.
2.Special talents The breed has high prey drive and an very intense sense of smell One of their talents is to be trained to find, by scent, Black Truffles (a type of edible mushroom) found close to the roots of some trees in the Western half of North America.
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.
• Ectopia lentis a congenital problem where the lens of the eye is displaced. Eye disease
• bite problems (malocclusions -teeth that are incorrectly aligned when jaw is closed.),
• Hip dysplasia, elbow dysplasia, (hip or elbow socket that does not fully cover the ball which increases the risk of displacement.
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.
1 Feeding the puppy Puppies should eat a minimum of a cup and max of a cup and three quarters each day. 1-13/4
2.Feeding the adult Adult Teddy Roosevelt Terriers should eat three-fourth to one-and-a-half cups per day.
3.Points for Good Health - fairly healthy The Teddy Roosevelt Terriers displays some common joint issues that are shared by Rat Terriers.
4. Games and Exercises Having descended from hunting/working dogs Teddy Roosevelt's are able to learn and work conformation rings, and agility trials. They like to play and take part in swims, hikes and playing fetch or Frisbee. They take well to obedience training.
