Both Thai Ridgeback and American Mastiff has almost same litter size. Thai Ridgeback requires Moderate maintenance. But American Mastiff requires Low maintenance
Until recently the Thai Ridgeback was not known outside of its native land. However, after being recently recognized as a standard breed, the dogs are getting some notice from the western world. They are one of three known ridgeback breeds with the ridge running the opposite direction of the rest of her fur. The other breeds with this characteristic are the better known Rhodesian Ridgeback and the even lesser known Phu Quoc Ridgeback.
The Thai Ridgeback is believed to have originated in eastern Thailand but there is no documentation of their actual history. The breed is thought to be descended from the Funan Ridgeback based on a genetic hypothesis. It is thought that the same Funan Ridgeback is an ancestor od the Phu Quoc Dog. This Funan Ridgeback lived over a century ago. Along with the Rhodesian Ridgeback, all have a common ridgebearing ancestor.
It is still unknown where the original ridge came from but it has been shown that all of the ridgeback dogs have the same genetic mutation and even though the Rhodisian is from Africa, there is not a parallel mutation. The Thai Ridgeback is an active, energetic, tough dog. He is loyal, intelligent, and has great jumping ability.
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 breed is medium in size and muscular in body. They have a wedge shaped head, a short coat that is smooth and pricked, triangular ears. The ridge on his back is pronounced as the hair grows away from the rest of the coat from the hips to the withers. Puppies can be born with or without the ridge. They are extremely agile. With what is often called a sword tail being carried up, the Ridgeback has wrinkles on his forehead, a black tongue or the tongue has black marks, and almond shaped eyes.
The coat sheds minimally and is dense, while the eyes are usually brown – in blue dogs they can be amber. The color of the coat is fawn, red, black or blue with a black mask on the reds. There are 8 different ridge patterns: Feather, violin, saddleback, needle, arrow, bowling pin, lute, and leaf. The broader the ridge the better the dog is considered for show.
There are two epistatic genes that determine the ridge and its size. The more genes of this type the individual dog has, the broader the ridge will be. There must be a dominant gene for the ridge to appear at all.
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.
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.
With such a mysterious origin, there are not a lot of documented episodes of genetic illness as the breed has been isolated in Thailand and natural selection has driven reproduction. There are only a few issues that they are genetically predisposed to. These include:
• Dermoid Sinus – this is a genetic skin condition known as pilonidal sinus as well. This is a defect in the neural tube and the sinus might be removed. If the sinus is wrapped around the spinal cord and cannot be removed it can be tied off.
• Bloat – can be terminal if not treated as soon as possible. Bloat is a distension of the stomach and intestines which can twist and tangle, killing the dog almost immediately without veterinary attention.
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.
1. Feeding the Puppy - Don’t over feed the puppy as they are inclined to become obese. Feed a high quality protein rich puppy for medium breeds. Feed in 3-4 smaller meals per day. As he grows be aware of bloat possibilities.
2. Feeding the adult dog - The risk of bloat is even greater in the adult and so is the risk of obesity. Don’t feed large meals and don’t feed before or after strenuous exercise. Feed in 2 smaller meals per day.
4. Games and Exercises – Energetic and needs serious exercise. She loves to swim, retrieve, hike, hunt, and catch frisbees. Likes search and rescue and guard dog work.
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.
