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 the Olympus Dog or even simply as the Greek Shepherd, the Greek Sheepdog is a large to giant molosser dog from Greece. His purpose has always been to guard flocks and livestock from predators and he has been around for hundreds of years, looking much like the Great Pyrenees.
It is believed that the dog was likely bred with a number of breeds – both local and non-local dogs.
Unfortunately there were no records kept of the development of the breed but today the Greek Sheepdog remains a rare and fairly unknown breed outside of Greece.
It's numbers are dwindling in Greece too and since 1998 the Greek ARCTUROS has made attempts to save the breed, starting the Greek Shepherd Dog Breeding Program.
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 Greek Sheepdog is a large dog, standing at 65 – 75cm and weighing roughly between 32 to 50kg. He is a dog that displays physical strength. He has a large head with brown eyes and a serious expression on his face. He has a thick double coat which is essentially white with red, black or brown markings.
You will also see tri-color dogs. He has floppy ears today but there was a time when the right ear of the male dog was cut off or cropped. The tail is long and bushy and it can be held low but also held up so that it curls over the back.
Maybe because of his size and him being a strong-willed, independent thinker, the Greek Shepherd may not be the best choice for a first time dog owner. Having said that, if you're a strong, firm, patient, kind person, then you'll be able to raise any kind of dog, first time or not.
The Greek Shepherd is a brave, loyal, calm, protective dog and with socialization and training, can make an awesome pet. They are dogs who are a bit suspicious with strangers, not making friends too easily. He loves his human family and wants to be part of their activities. He can't be left on his own day after day as this can lead to excessive barking and destructive behavior.
They've been dogs used to working with livestock and they will certainly need to be taken on daily walks and involved in rough and tumble games as they thrive on activity. The dog won't fit easily into city life where there is just a handkerchief-sized garden as he needs space and activity.
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.
Your Greek Shepherd is an intelligent, independent dog who likes to show his loyalty and devotion to his owner.
He is a protective dog too and when trained and socialized makes an excellent family pet. These Molosser type dogs are formidable dogs known for their bravery and courage.
They're the type of dogs who like a strong leader-type of owner and when he gets someone who he can look up to as his leader, he becomes a loyal, devoted pet.
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.
With good care and lots of love, this dog can live to be between 10 to 12 years of age. He is unlikely to get sick very often, but still it it wise to know of some of the health issues than can occur with large breed dogs like this.
This is a disease of the heart muscle. The heart is enlarged and unable to have the right heart rhythm. The distended muscle isn't able to push the blood through the heart chambers to where it is needed. Cause for this dilated heart can be genetic, nutritional, infectious or metabolic.
Because taurine and carnitine are involved in good heart function, and low levels of these amino acids can cause symptoms of dilated cardiomyopathy, supplementation is useful, especially if you feel your dog isn't getting in the right kind of food.
Borreliosis, a bacterial infection, causes Lyme disease, transmitted by the Ixodes tick. The tick bites the dog and the toxins gets into the dog's bloodstream, with the bacteria travelling to different parts of the body.
Typical symptoms in a dog includes loss of appetite, fever, no energy, swelling of joints and lameness, but symptoms can progress to kidney failure too or cardiac problems. Treatment will include antibiotics.
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 coat of the Greek Shepherd is fairly long so it will need to be brushed at least twice a week to keep it free from matting and tangling. He is an average shedder and the brushing will remove all loose hairs, keeping the coat sleek and shiny.
Feeding your Greek Sheepdog requires giving him top quality food as this will ensure he is healthy and can ward off common dog illnesses. If you're going to be feeding him kibble, make sure to go for the top quality brands, and as a treat for your pet you can add in some brown rice, pasta, brown bread, cooked chicken and vegetables.
Dogs are essentially carnivores and he will need to have some raw meat such as beef added into his kibble from time to time. He should never ever be without a constant supply of fresh, cool water.
