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 as a cattle herding dog breed, the Corgi hails from Pembrokeshire, Wales. You get 2 breeds – the Cardigan Welsh Corgi and the Welsh Corgi.
The word ‘Korgi’ actually means ‘dwarf dog’. According to some, the small dog’s history goes back as far as 1107AD, but when you start doing research, you find that the Pembroke Welsh Corgi doesn’t have a traceable breed history.
The Pembrokeshire Corgi was officially recognized by the Kennel Club in the United Kingdom in 1934 and is a breed separate from the Cardiganshire Corgi.
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 Corgi is a small to medium sized dog, standing at 25 to 30cm and weighs between 10 to 14kg.
The coat of the Corgi is fairly short to medium length and is thick. You’ll find him to be available in colors such as red, fawn, black and tan and with white markings.
He has a sharp, intelligent face with an amicable expression. Looking much like a fox with short legs, he has a long, low-set body body and is a sturdy dog. His ears also stand erect and he has a docked tail.
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 sweet little Corgi is well known with his association with Britain’s Queen Elizabeth who has always loved these dogs with their long bodies and short legs. But while the Corgi may well be associated with royalty, he isn’t too snooty by any means to be your pet.
He has got a wonderful personality, and he is just waiting to be allowed into your household where he will prove to be a loving, devoted companion and friend.
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.
A corgi, when he is well looked after, can live to be anything from 12 to 15 years of age. However even this sturdy dog may well be susceptible to some of the more common dog illnesses, such as hip dysplasia and degenerative myelopathy.
Also you have to be careful with your Corgi and make sure that he doesn’t gain weight as this weight gain can bring with it a host of health complications.
Hip dysplasia with your Corgi is about an abnormal joint structure where the bones lose contact with each other. This parting of the bones is known as subluxation, and it is this subluxation that can cause your pet pain and discomfort and lead to osteoarthritis.
This disease isn’t reserved for old dogs either, and some young dogs can begin to show signs of this disease before they reach their first birthday. Without taking your dog to the vet and having medical intervention, your pet may eventually be unable to walk.
It is so sad when Degenerative Myelopathy invades your pet as it is a devastating disease watching your pet become paralyzed. The disease seems to come on when then dog is between 8 and 14 years of age where your pet loses co-ordination in the hind limbs, getting worse until he can no longer walk. Often your dog can no longer control his urine output.
There are no real treatments that have stopped the progression of the disease and your vet may suggest treatments that can make your pet more comfortable You vet may compassionately suggest your dog be put down, particularly for those people who can’t afford treatment.
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.
The Corgi isn’t a particularly heavy shedder, so a brush down twice a week will be excellent for his thick coat. And of coarse he will thrive on the attention given to him during the brushing session.
Corgis love walks and sniffing around as they go along. They’re energetic dogs so you’ll need to include him in your daily walks which he just loves, and include him in some ball games.
Corgis may be short in stature but they are robust dogs – sturdily built. They are active dogs and can use up a lot of calories. They will certainly require a diet that features good quality protein.
Feed your Corgi a good quality food designed for special life stages – puppy, adult, pregnant female, senior dog and also dogs with illnesses.
Most Corgis do well having 2 meals of kibble a day. Puppies usually eat 4 meals a day until they are old enough to move onto an adult feeding schedule. Include cooked rice, meat and vegetables in his diet as well as raw meat from time to time and ensure there is always a bowl of clean, cool water available.
