History

newfoundland dogThe Newfoundland dog is a large working dog. They were bred and used as a working dog for fishermen in the Dominion of Newfoundland, an eastern province of Canada. With their web feet they were also used for water rescue.

The history of the Newfoundland Dog is unsure, but the breed as we know it today originated from dogs which were brought from Newfoundland to England in the early 1800's.

The Newfoundland Club was founded in 1886 so as to promote the breed.

american mastiffThe 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.

Description

newfoundland dog puppyThe Newfoundland is a large dog standing at between 63cm to 74cm, both male and female. Weight can vary from 45kg to 80kg.

He has a double coat of medium-length straight hair and the hair can be black, brown or gray. Although it is common for the Newfoundland to have a solid-colored coats, you will sometimes find small patches of white on their chest, toes, or at the tip of the tail. Then again you get the less common Newfoundlands where the coat is white with some black markings and these are known as Landseers.

The outer coat is coarse, oily and water-resistant quality, suited to a dog that loves to spend time in the water. The head is broad and large with small ears that he keeps lying close to his head. The tail is long and plumed and the feet are wide with webbing between the toes which aids him with swimming.

Temperament:

As with many large dogs, the Newfoundland is docile and his sheer size makes it that he is best suited to life in the countryside as opposed to living in the city. This is also because this particular dog wants to be close to water where he can swim.

He is a trustworthy, loyal dog and will get on well with children and pets in the home. Training and socialization is always recommended for any dog, but a big dog can often ‘get in the way’ indoors and you want him to lie down or sit when you tell him to. He is an intelligent dog so will respond well to training.

american mastiff puppyThis 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.

Health Problems

newfoundland dog dogThe Newfoundland can be prone to serious health conditions such as hip dysplasia and gastric torsion. Deep chested dog breeds like the New Foundland are susceptible to bloat, a life threatening condition where the stomach swells, it can twist and the dog can die if help isn’t available. He will be salivating, restless and whining while also trying to vomit.

Giant breeds are also prone to elbow and hip dysplasia, a genetic problem which can ultimately affect your dog’s mobility.

When in any doubt about your pet’s health, get him to the vet.

american mastiff dogAmerican 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.

Caring The Pet

Grooming:

newfoundland dog puppiesYour dog’s coat will need to be brushed at least twice a week as he is a heavy shedder.

Do the nails of your dog as soon as they start getting long. Long nails can hook on things and cause injury to the dog’s paw area.

This is a dog with floppy ears so check inside the ears to prevent ear infections, more so because this is a water-loving dog. The dampness inside the ears can cause bacteria.

Diet:

This is a giant breed and sadly, they have the shortest lifespans. You want to make sure that you keep your giant breed as healthy as possible to ensure he reaches the 10 or so years allotted to him and to also prevent health problems.

Make sure your giant breed puppy and adult has the very highest quality commercially manufactured food to ensure he gets the right balance of nutrients in. This food also makes sure that your puppy rather grows at a slower rate and stronger as opposed to growing too quickly. Rapid growth comes with joint problems.

All dogs, large and small, don’t want exotic, strange food that upsets their stomachs. They want consistency and simplicity and they want tasty food. Give him some homemade food such as cooked chicken, brown rice or pasta and some vegetables such as sweet potato, carrots and spinach. You can add this occasionally to his dry kibble.

Add in some raw meat from time to time too. Your pet will be strong, healthy, happy and content.

american mastiff puppiesGiant 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.

Health issues

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.

Exercise and games

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.

Characteristics

newfoundland dog dogsYour beautiful, cuddly puppy will soon become a giant dog with a big appetite. Don’t just buy a cute puppy if you can’t afford to feed him properly and you can’t give him lots of attention.

Your dog will also be shedding, so be aware of these aspects before you bring a large Newfoundland into your home. He is a gentle dog, but his size could be worrisome if he isn’t trained, socialized and supervised.

Newfoundlands are amicable dogs, and while he may like to spend times indoors with you relaxing, he is a working dog and will require exercise and activities for mind and body.

Give this giant of a dog a loving home, and you will have a special, devoted friend like no other.

american mastiff dogsA 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.
