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.
The Shih Tzu is an Imperial Chinese breed developed by palace breeders hundreds of years ago with breed stock from the Tibetan lines. It is quite probable that the Shih Tzu was originally a cross between two Sino-Tibetan ancient dogs – the Pekingese and the Lhasa Apso. Based on their looks, the Shih Tzu means the lion dog, but they were really very pampered palace dogs living with the Chinese emperors and families. The emperors were always gifting the breeders who developed the most affectionate, gentle and beautiful Shih Tzus.
Until the 1930’s the Shih Tzu was not known to the world outside the emperor’s palace. Once the breed did come out from behind the palace walls, they were immediately popular. Much debate went on about how to refine the breed as clubs began to spring up in Peking and then in England. It was not until 1969 the Shih Tzu was recognized and entered in the AKC Stud Book.
While the original Shih Tzu might have been a mix between the Pekingese and the Lhasa Apso, today’s breed spread around the world after the second world war. In Europe in the 1930’s the breed was classified as Apsos. In 1935 the first Shih Tzu Club of Europe was formed, and the first standard was written, and the breed was categorized as the Shih Tzu.
Following World War II, soldiers brought the dogs to the States from Europe. By the 1950’s the breed was growing in popularity and the AKC recognized the breed in 1969 as members of the Toy Group. They are now recognized by all major kennel clubs throughout the western world. They are recognized by the Federation Cynoloqique Internationale in the Companion and Toy Group, among Tibetan breeds.
The Shih Tzu is a good watchdog, but it was bred to be a companion animal. It is a friendly, open breed that welcomes strangers. They are great with other animals and children as well as adults.
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.
This is a breed of lively, sturdy and alert little dogs with a beautiful double coat that is flowing and long. In its full glory the Shih Tzu coat is touching the floor all the way around the dog. The dog’s bearing is as royal as its history, arrogantly carrying his head high and his tail curving over his back.
The Shih Tzu is a solid, compact breed with weight and substance. They may be a small dog, but they are a strong one. They have large dark eyes with a short muzzle and fur covered drop ears. They are just a little longer than they are tall with a distinct underbite.
There are a few differences between the European or UK Kennel Club standard and the American Kennel Club AKC standard. As opposed to the UK standard the AKC standard states that:
• The hindquarters are muscular while the front are straight. They are balanced in that they are not too long or too short.
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.
2.Special talents – they were bred to be companion animals. They are friendly and loyal.
3.Adaptability Yes very much so. They can live in an apartment or on a farm. It doesn’t matter and they don’t need a yard.
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.
For many breeds that have the advantage of isolation like the Shih Tzu did with the emperors of China usually have very little genetic health issues. Most of the breed is indeed healthy but there are some issues.
• Brachycephalic airway obstructive syndrome due to the shape of their face and head causes them to have breathing issues. They cannot handle heat and they cannot swim. They can have an upper airway obstruction that makes it hard for them to breath. If this is bad enough, surgery may be required.
• Hypothyroidism – thyroid does not produce the hormones necessary for metabolism to work effectively. This can lead to weight gain, hair loss, lethargy and muscle loss. It can be treated effectively.
• Issues of the eyes include – cataracts, corneal dryness and inflammation, progressive retinal atrophy, improperly closing eyelids and retinal detachment.
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 – this is a toy dog so don’t overfeed. They have a tendency to become obese. Calorie and weight level need to be calculated with any diet you feed. The diet should be high quality with plenty of protein made for toy dogs. Feed the puppy at least 3 times a day, maybe four in very small amounts, never more than ½ cup per day.
2.Feeding the adult - this is a toy dog so don’t overfeed. They have a tendency to become obese. Calorie and weight level need to be calculated with any diet you feed. The diet should be high quality with plenty of protein made for toy dogs. Feed the adult once or twice a day in larger amounts than the puppy but never more than ¾ of a cup per day.
3.Points for Good Health - most Shih Tzu’s are hardy with exceptionally good health.
This is a pampered, not high energy dog. However, she still needs playtime, which can be indoors and short walks outdoors every day.
