The Greenland dog is an ancient breed of dog hailing from Greenland. The dog was brought to North American from Siberia hundreds of years ago. In fact the very first dogs arrived in the Americas some 12,000 years ago.
The Greenland Dog isn’t recognized by the AKC but it is recognized by a number of other groups. While the Greenland Dog is valued in Greenland, it isn't particularly well known in other parts of the world.
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 Greenland Dog is a heavily built dog, and between the males and females, this medium to large sized dog can be 51 – 68cm in height and weigh 30 – 35kg.
He has the typical slanted eyes of the husky-type dogs with a keen, alert expression in them. He has small triangular erect ears. The long, bushy tail of the dog is curled over the back of the dog.
The coat is short to medium length and has 2 layers with the outer layer being fairly coarse. The double coat is thick and shortish but also stand-offish, meaning the hair doesn’t lie flat against the dog’s body. Color of the fur is a mix of cream, beige, white, tan, black, grey or silver.
As a working dog, the Greenland Dog is known for its strength, its boisterous nature and speed. Because its a dog that has worked as a pack, it wants a firm, patient, fair, confident owner to bring out the best in him. Being intelligent, independent and work-orientated, it is perhaps not a great choice for the first-time dog owner who may be out of their realm with the demands of these high-energy dogs.
The dog is independent, but he is quite capable of forming a strong, loving bond with his owner. This is certainly a dog that is never going to thrive if he has to lie around the house all day – he is an active dog who wants a task to do and he is going to need plenty of daily exercise.
They’ve always had active lives pulling sleds or hunting for seals and he craves this busy, active lifestyle. He is the kind of dog that shouldn’t live in the city with a tiny garden unless he has an owner who takes time to walk him and exercise him vigorously. He is a dog that will require training and socialization.
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.
Bred as a working dog, the Greenland Dog, native to Greenland is a high energy dog who is boisterous, lively and social. With training and socialization, he becomes an obedient, loyal and devoted pet.
While he is quite capable of being an awesome domesticated pet, he is essentially a working dog, loving having to be part of a very active lifestyle. He may not be the best pet for a first time owner or a home with small children. This is because he isn't your cuddly, lying-around-the-house, playmate kind of pet. He wants a home and owner similar to himself – strong, active, energetic, bold, independent, strong-willed and firm, and when he gets this, he becomes the splendid pet he is so well known for.
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 Greenland dog can battle with eye problems such as progressive retinal atrophy, hereditary or juvenile cataracts and corneal dystrophy. Eye diseases like this can cause a host of problems for your pet and should receive immediate veterinary attention.
Cataracts in dogs are a common problem affecting the eyes of dogs, with there being different forms and causes.The age at which your pet develops cataracts is important for identifying the type of cataract it is because it will give the vet an idea if the cataracts are an hereditary trait in certain dog breeds.
Nearly every dog can battle with hip dysplasia and it can be a serious concern for active canines such as the Greenland dog.
This joint and bone ailment can start manifesting itself as early as 4 months of age with your pet. This dysplasia occurs when the head of the femur doesn't fit into the pelvic joint the way it should. It can lead to pain, arthritis and lameness with your dog.
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.
As a medium- to large-sized dog breed, the Greenland Dog will require a high-quality commercial dog food if that is what you will be feeding him. The top quality brands have the right mix of vitamins and minerals in them for health.
However, it is wise to ensure that such an active dog breed gets his quota of raw meat in too. He has been used to eating fish and seal meat and will require this raw diet too. Sometimes if you cook rice, chicken and vegetables, you can add this into his kibble too.
Greenland Dogs need to be groomed at least twice a week to keep the thick coat in tip top condition. He sheds throughout the year.
He will also require you brushing his teeth to get rid of plaque which can cause a host of health issues. You get special toothpaste and toothbrush for dogs. His teeth should be brushed 2 or 3 times a week.
Make sure you give your high-energy Greenland Dog the right dose of exercise. He is intelligent too so he needs walks, games and other activities that contribute towards his physical and mental wellbeing.
He will do well on large properties or farms but won't do well where the space is tiny and where the owners are inactive couch potatoes.
Be careful too that the Greenland Dog isn't exercised immediately after eating as this puts him in danger of developing bloat.
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.
