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.
Looking much like the Black and Tan Terrier, the Manchester Terrier is a dog that was actually developed from the Black and Tan, which is the oldest known breed of terrier.
In the United States there are 2 varieties of the Manchester Terrier — the Toy and the Standard but in the UK the 2 sizes are classified as different breeds - the English Toy Terrier and the Manchester Terrier.
The dog was first bred in the 19th century to wipe out rats and mice, originating from Manchester, England. This is an old dog breed, gaining the nickname of the Gentleman's Terrier because of its dignified looks and personality.
After the 2nd World War, the numbers of the dog dropped and this spurred the kennel club to list it as a vulnerable native breed, in danger of extinction. It was in 1937 that the British Manchester Terrier Club was formed.
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 Manchester Terrier is a small, smooth haired dog with a black and tan coat and a head with a fairly long muzzle, small bright eyes, largish erect ears and a deep chest.
The body is lean and muscular and the tail, where once docked, now tends to be left long. In the toy sized dog you will find him standing at roughly 25 – 30cm in height and he will weigh between 2 to 4kg. The standard sized dog will be slightly taller and heavier and weigh in the region of 8kg.
You can expect between 2 – 4 puppies from a breeding pair.
Feisty, energetic, alert and intelligent are some of the words which describe the Manchester Terrier. Like any other dog, training and socialization will make him a splendid pet, obedient and amicable among people.
He is loving and loyal, courageous and feisty and guaranteed to make you an eager-to-please pet. He can adapt to life in the city or countryside, but is going to need plenty of exercise wherever you keep him as a pet.
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.
The Manchester Terrier has so many good qualities that make him such a good pet. Low maintenance, he is clean and well groomed to look at. He is also a healthy dog breed, nice and active and low maintenance.
This little dog is willing to come into your home and heart. He will make you a wonderful pet and friend for as long as 15 years if you take special care of him.
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.
This dog breed is fairly healthy and can reach a good age if looked after well. Every dog though, can be affected by a number of inheritable genetic disorders.
Glaucoma is a common genetic condition in Terrier breeds, including the Manchester Terrier. Secondary glaucoma, which is known as lens luxation is brought about when there is excessive pressure in the eyeball. The lens of the eye is put out of alignment. Most times surgery is the solution.
Von Willebrand's Disease is a blood disorder that affects the clotting process. A dog with this disease will have bleeding gums, continuous bleeding after surgery and sometimes blood in the stool. It’s a disease which can’t be cured but it can be managed with treatments.
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.
Low maintenance, the Manchester Terrier will only require a brushing once or twice a week. Check his eyes and ears for infections, clip his nails and brush his teeth 2 or 3 times a week.
The Manchester Terrier is a lean, muscular dog and you want to be sure to keep him that way. If you feed him commercially manufactured food, make sure that it is one of the high quality brands – food which is packed full of vitamins and minerals to ensure the health of your dog.
Any packaged food you buy should be appropriate to the dog’s age and his activity levels. You won’t be doing your dog a favor by feeding him treats that you enjoy such as chocolate, coffee, peanuts, raisins, grapes and onions.
Dogs want simple food that don’t change much. Keeping things simple prevents upset stomachs. Give him some wholesome home-made food occasionally to add into his dry kibble. This can be boiled chicken, brown rice or pasta and some cooked or raw vegetables such as potatoes, carrots and spinach. Some raw meat added in from time to time can also do wonders for your dog. Make sure he has access around the clock to fresh, cool water.
The Manchester Terrier wants lots of exercise, and apart from him having his regular daily walks, he will need runs off the leash in the park. If you go cycling for instance, he will readily run beside you.
