American Mastiff may weigh 80 kg / 177 pounds more than Brazilian Terrier. Both American Mastiff and Brazilian Terrier has almost same life span. Both American Mastiff and Brazilian Terrier has almost same litter size. Both American Mastiff and Brazilian Terrier requires Low Maintenance.
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.
Though its exact origins are questioned it is known that the Brazillian Terrier was developed in Brazil and along with the Fila Brasileiro, are the only authentic Brazillian breeds. In the early 1800’s the Jack Russel Terrier, Fox Terrier, Chihuahuas and Miniature Pinschers were mixed to create the Brazillian Terrier. The Terrier breed was brought to Brazil by Europeans and there were probably both the Jack Russel and the Fox Terrier in the mix. Very popular within its own country the Brazillian Terrier is barely known outside Brazil. They were registered in 1973 even though they have been around in Brazil since the 1800’s. They are both single and pack hunting dogs. They chase and surround prey until the prey becomes too exhausted to run or fight. The Brazillian Terrier is larger than any European or North American Terrier. They are also less aggressive than other terrier types so that pack hunting became possible. They were built to work in the heat for long periods of time. Their stamina far surpassed other terriers as did their resistance to parasites and diseases.
Many farmers and plantation owners came to values them for their ability to hunt down and eliminate vermin on the land and thus help with increased production of livestock and crops. They were so loved by the farmers and plantation owners that they began known as the “dog of the common people”. Yet it was not only the rural folks who valued this breed, but the people of the cities did as well. Because they were good ratters, a reasonable size, affectionate and loyal, many urban households sported a Brazillian Terrier. The breed spread throughout the country.
The Brazillian Terrier was kept mostly pure bred throughout its history but due to lack of pedigrees and paperwork it was not recognized by any kennel club unit 1973 when Brazillian breeders formed the Clube de Fox Paulistinha or CPF. They had a standard developed and created a stud book. By 1991 they were still not officially recognized but the CFP and the CBKC (Confederacio Brasilera de Cinofilia) began the process of establishing acceptable pedigrees and recognition of the breed. The FCI recognized the breed in 2007.
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 Brazillian Terrier is a small to medium sized dog with a white – tricolor (tan and black) coat. It has a narrow chest, a triangular rather flat skull, the tail is docked, folded, half pricked hears, and the body is well-balanced. Its legs are long and athletic, and the coat is very short and very fine. He has round eyes that can be green, blue, brown or gray. They are very much like the Jack Russel in temperament. His expression should reflect that temperament in its eagerness and alertness.
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 Brazillian Terrier is very much like his ancestor the Jack Russell. Like the JR Terrier he is friendly, intelligent, alert, playful, and loves to dig. They are courageous and fearless. They will obey but only if they know and believe you are really in charge. Otherwise they are intelligent enough to be very independent, determined and willful. At the same time, they are utterly loyal to their people. He needs a lot of toys but don’t let him live with other small animals. His hunting instincts may be the strongest of all terriers and he may harm small animals in the home. You have to teach him when to stop barking. Their love of play would consume your entire day if you let them. You should understand the terrier personality before you acquire a Brazillian Terrier.
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.
The breed is mostly healthy except for hunting accidents and a few generic issues they are susceptible to. This includes things like Dental and eye issues, the usual ear issues, liver issues, allergies, epilepsy and patellar luxation. However, they are more likely to have issues related to hunting than another of these predisposed conditions
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.
This is still a working dog and a terrier at that. They are high energy, athletic dogs. Feed a high-quality food at the rate of 1 to 2 cups per day, split into 2 meals. Treat are good for training but if your Brazillian Terrier is not hunting or working in some way, stay away from too much food and treats as he can easily become obese.
As mentioned previously, the biggest concern with this breed is hunting accidents or injuries. Look out for ear and skin infections or allergies. For the most part this is a hardy, healthy breed.
A very energetic dog, the Brazillian Terrier like its ancestors has a need to work off that energy. Yes, he is an urban dog and can live in an apartment, but you better have a dog park or a competition or some place to hunt because his need for exercise cannot be answered by daily walks and running around an apartment. IF your Brazillian Terrier is not stimulated physically and mentally on a daily basis he will become destructive, hyperactive and very, very unhappy. Don’t just stick him in a yard and leave him either as terriers are known to dig and escape and he will too.
They excel at agility, flyball, obedience and confirmation. They love to chase things and they love to explore. Barn Hunt would also be a good game for them. They are very smart, so their physical exercise should be paired with mental stimulation.
