American Mastiff may weigh 72 kg / 159 pounds more than Dunker. American Mastiff may live 3 years less than Dunker. American Mastiff may have less litter size than Dunker. Both American Mastiff and Dunker 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.
Known as the Norwegian Hound, the Dunker hails from Norway. Bred and named after breeder Wilhelm Dunker to be a robust scenthound, Norwegian Scenthounds were crossed with a Russian Harlequin Hound because this particular dog was an excellent scent trailer and it could stand up to the freezing conditions of Norway.
The Dunker become popular in the mid-19th century in other Scandinavian countries. Hunters liked its intelligence, its robustness and its speed and strength. In 1902 a club was founded for the breed and in the same year the Norwegian Kennel Club recognized the Dunker.
The Dunker started dying out after the war, and in the late 1980s breeders of the Dunker petitioned to allow them to cross the remaining Dunkers with scenthounds. Today the dog is known in Norway but is uncommon outside Scandinavia.
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 Dunker is a medium sized dog which stands at between 50-55cms with females being slightly smaller at 47-52cms. They usually weigh between 11-18kg and look similar to other scenthounds, being muscular and athletic.
The ears of the Dunker are floppy, the tail is long and carried straight with a bit of a curve, the nose is large and black as well as the eyes, but some dogs have light eyes which can even be blue.
The coat of the Dunker is straight and dense and this coat of his is well known for the unique color of the coat – blue or black dappled, while some dogs will have black, tan and white markings. White faces are preferred but you will find dogs with black masks.
This is a non-aggressive dog and can become quite friendly when trained and socialized.
They are dogs that form strong bonds with their owners, being particularly good around children. They get on well with dogs and other pets in the home.
They’re intelligent dogs and are are easy to train. In fact, training and socialization is recommended for this dog as he does tend to be a bit stubborn.
Training ensures he is relaxed and obedient. He is an active dog and will certainly require some exercise each day. He’ll respond willingly if you call him to join you in your jogging- or cycling outings.
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 Dunker is such a good tempered dog and he will be happy to settle in the city or the countryside with his owner.
When you look at his history, he is a hunting dog, used for hunting rabbits. Being an active breed, he is better suited to living in a home where there is at least a fair sized garden.
He isn’t a high maintenance dog either, so no special attention to grooming is required. Being a fairly healthy breed, he isn’t likely to develop any serious health issues too. This low-maintenance, undemanding Norwegian Hound makes a splendid 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.
The Dunker dog can live to reach a ripe age of 12 to 15 years. There are some health issues he may face -
Partial or complete hearing loss can come about because of dirt or wax build-up in the ear canals. It can be because of an untreated ear infection, an injury or even old age.
Your veterinarian can examine your dog’s ear canal. Certain dog breeds such as the Dunker and others are more predisposed to deafness and you’ll find your dog responding slowly to your voice or he may be totally startled when woken.
Your vet will determine the type of treatment for your dog if an ear infection for instance is suspected. Treatment in this case may involve cleaning wax out of the ears or getting rid of overgrown ear hair.
Hip dysplasia is an inherited condition with your dog where bone rubs against other bone. Your Dunker dog will be in pain and his movement could be limited and he may even become lame. Get your pet to the vet because there are a number of treatment options.
Take a look at your pet’s eyes so that you’re aware of cloudiness, inflammation, discharge, a change in eye color or red eyelid lining. Take him to the vet if you suspect something serious, but in the meantime you can also gently wipe over your pet’s eyes to remove any discharge.
If you do need to bath your pet, make sure to protect his eyes before applying any lotion.
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 Dunker is a dog with stamina and energy and he will need a walk every day as well as some other forms of vigorous exercise. The idea is to involve a dog like this in all your activities, whether you go running, swimming or cycling.
The Dunker isn’t going to require you to spend a lot of money on maintenance for him. A good brush-down twice a week will be adequate as he is a fairly heavy shedder and brushing him will get rid of all those loose hairs. It is also time to check him over for fleas and ticks too.
Other grooming aspects to check will include nail trimming, checking the inside of the dog’s ears for excess wax build-up and dirt.
Dental care is of major concern because teeth left unattended can result in mouth bacteria. This bacteria enters the blood stream and results in systemic infection. Sometimes the bad teeth can be so painful that a dog no longer wants to eat.
It is imperative to brush your pet’s teeth at least 2 or 3 times a week with a special dog toothbrush and toothpaste.
