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 Karelian Bear Dog is a Finnish Spitz-type dog who is regarded as a national treasure in the country. They have always been noted for their hunting skills, and because the dog has been found in ancient Viking graves you can assume it is an ancient breed.
In fact the ancestry of the dog can be traced to neolithic times, when dogs followed human settlers to regions of Scandinavia and Europe.The American Kennel Club does not fully recognize the Karelian Bear Dog. It is however included in their Foundation Stock Service.
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.
Standing at between 54–60cm in height and weighing roughly 20–23 kg, the medium sized Karelian Bear Dog has a beautiful shiny coat. The outercoat is shortish, straight and dense and the undercoat is soft and thick.
The color of the coat is black with white markings. The dog has a bushy tail which curls in a circle over the back and the tail’s end is white. The ears of the dog are small and erect while the small eyes are intense.
It is best to have your Karelian Bear dog trained and socialized as he can tend to be aggressive towards other pets in the house, and even towards people he isn't familiar with. The owner of these dogs must be firm and fair with training as the Karelian is a strong-willed dog.

He is a very social dog and just loves spending time outdoors with his family. He is also good with children in the home as he is a playful dog.He is a dog who is going to require a lot of space to use up his energy. He needs a lot of mental and physical stimulation, as in the past he has always had a lot of work to do, and just loves being active. He is a confident, brave dog who takes his job as family protector seriously.
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.

They love to please their people and being highly intelligent they learn fast.

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 Karelian Bear Dog can reach 10 to 12 years of age with good care, but just like with other dog breeds, he can be prone to certain health problems such as eye and dental problems as well as hip dysplasia.
Many people don’t realize that dental problems are far more serious than what they imagine. An offensive breath can be the first warning sign of tooth decay with your canine friend.
There are other problems that can develop orally for your dog and these include inflammation of the gums, swollen gums and mouth tumors. You need to brush your pet’s teeth but also see to it that he goes for regular dental check-ups at the vet.
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.
There are many people who just keep a dog for watchdog purposes and fail to make the pet a proper family member by meeting its physical and emotional needs.
Caring for a dog means providing nutritious food and clean drinking water, seeing that he has a warm, dry place to sleep, providing the dog with exercise and ensuring the dog is healthy and content.
Caring for a dog is a big responsibility, and you have to think carefully before you bring a dog into your home and life.
You need to be careful with the food you select for your pet. If you’re feeding him a commercially manufactured food, you need to make sure to read the label and make sure the top ingredients are meat and not meat by-products. If this is something you’ve never thought about, ask your veterinarian for food recommendations.
Speaking of veterinarians, make sure you have a reliable, reputable vet you can call on. At some time or other your pet may get sick and then you want to have the name of a reliable vet in your contacts list on your cell phone. Sometimes your pet can become suddenly sick where he will need immediate, emergency help from the vet.
Just like you look after yourself, you need to look after your pet by brushing him, checking him for fleas, ticks and worms and keeping an eye on his eyes, ears, teeth and general health.
