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 also as the Portuguese Mastiff, the Rafeiro do Alentejo comes from Portugal and has always been used as guardian for livestock. Their numbers declined quite a bit when there was no longer a need for this kind of job.Today it is essentially a companion dog.
The official standard of the Rafeiro do Alentejo was established in 1953. The dog is is recognized as a breed by the Portuguese Caniculture Club as well as the Federation Cynologique Interationale.
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 Alentejo is a large dog standing at between 64 and 75cm in height and weighing 45 to 60kg. He is a powerful dog with a deep chest, dark eyes, floppy ears. His coat is short to medium length, thick and straight. The color of the coat is a mix of fawn, a wolf grey, white, cream and black.
This is a serious dog with a calm demeanour about him. It doesn’t matter how calm he is though, as every dog will require training ad socialization if you want to enjoy having an obedient, well mannered dog around you. This is particularly important with a large, independent, self-confident, territorial dog like this.
He isn’t an aggressive dog but he is protective, wanting to guard and look out for his human family. They are dogs that get on well with children and other pets in the home, being wary of strangers.
They’re not recommended for life in small properties in the city as he requires a large garden at least.
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 Rafeiro do Alentejo is a quiet dog, but intelligent and strong-willed. Training and socialization will make him easy to get on with.
He will become an excellent companion, and can come indoors because he is well mannered and considerate. He was bred to be a guard dog, and the responsibilities he had taking care of livestock has been transferred to looking out for- and protecting his human family.
He makes a wonderful pet and companion, even with children and other pets, more so when brought up correctly by loving, firm, consistent dog owners.
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 Rafeiro do Alentejo is a generally healthy dog breed, and with good care can get to 11, 12 or 13 years of age.
Of course with a large dog like this, it is always a good idea to be aware of canine hip dysplasia, particularly because this is a large dog with a deep chest.
This makes him also vulnerable to bloat, a condition where the stomach swells with gas and which can be life threatening. Other things to watch for are ear infections and parasites.
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.
Make your grooming time with this serious, calm canine friend of yours a special bonding time. His coat simply requires a brush twice a week to keep it healthy and shiny.
While bushing him, run your hands over him to make sure there aren’t any unusual lumps. Check inside the floppy ears to make sure they’re not red which could be the start of a painful ear infection.
Look a his nails and trim them if they’ve become too long. Check inside his mouth and make sure there aren’t any black, rotten teeth as this can seriously impact the health of your pet.
Options for exercise will include long walks and a chance to run off his leash. In the back yard it will be to his benefit to throw balls for him to fetch. You can even bring him indoors and play some calm games with him. He should have exercise every single day.
Good food is needed for good health. It is always convenient to make use of the commercially manufactured dog foods there are on the market.
You don’t want to feed this to your dog day after day so provide your pet with some tasty home-made food too. Dogs want simplicity and consistency with their diets so they don’t battle with upset stomachs and an unnecessary trip to the vet.
Some home-cooked food twice a week and added to the dry kibble can keep him healthy and happy. Boiled chicken, sweet potatoes, brown rice or pasta, carrots and spinach will be perfect for him. Chop the food up finely and add it into the dry kibble once or twice a week.
Some people even cook it in bulk, refrigerate it and warm up small portions to add to the kibble. Raw meat added in occasionally can also be a good treat. Make sure your pet is never without a constant supply of fresh, cool water.
