Both American Mastiff and Great Dane are of same weight. Both American Mastiff and Great Dane has same life span. American Mastiff may have less litter size than Great Dane. Both American Mastiff and Great Dane 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 Deutsche Dogge or Apollo of dogs, the giant-breed Great Dane hails from Germany and not Denmark as many people believe.
The large Great Dane has been around for about 400 years already. They descend from mastiff-like dogs, being needed to protect country estates.
In the 18th century, apart from watching over estates, they were also popular with the upper class for sport.
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 Great Dame is a tall, lean, athletic, muscular, elegant looking dog. He can stand anything between 76–86cm in height and weigh around 54–90kg. The large head is long and narrow, and the medium sized floppy ears can be left or they can be cropped.
The tail is long and held low. The coat is short and smooth and can be in several colors such as fawn, black or brindle.
Any kind of aggressiveness was bred out of the Great Dane and today he is a gentle giant of a dog, getting on well with other dogs, children and everyone in his human family.
Even though he is a gentle giant, he will still require training and socialization just because of his size. Then they become the devoted pet that they are so well known to be. You'll want to know that when he comes indoors, he will obey you when you tell him to lie-down, sit or come, otherwise his sheer size will see him knocking things accidentally off table-tops.
He is an intelligent dog and is eager to please so he'll learn easily. He craves human companionship, so make sure that your social Dane has plenty of interaction with you.
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 Great Dane is a large breed, bred to hunt wild boar. The intelligence, bravery and fearless nature of the dog meant that he was sought after for this task.
Known as the Apollo of Dogs, you won’t find the Great Dane being used for hunting purposes anymore, being more suited as a companion dog.
While developed as a working breed, today he is a well balanced, intelligent, calm, loving, social, dependable dog that just wants to be loved by his human family and to provide love, loyalty and companionship back in return.
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.
Typically of giant dogs, the Great Dane doesn't have a particularly long life-span and will live to be about 8 to 10 years of age. Also, giant-breed dogs like this are susceptible to what is known as bloat.
You'll notice it because there is swelling of the stomach with gas buildup and also twisting of the stomach. It's a life-threatening condition and you'll need to get your dog to the vet as soon as possible. You can combat it by feeding him smaller, more frequent meals and perhaps buying a slow-feeder dish, forcing your hungry pet to eat slower and not gulp his food down.
Also, large dogs like this can develop hip dysplasia and with a dog like the Great Dane, it takes a while for the bones and joints to grow and then become stable. That is why it is important not to make him do any vigorous exercise till he is at least 18 months of age, as these exercises can put a lot of stress on the joints and bones which can lead to hip dysplasia later on.
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.
This is a large dog so you’ll notice that with commercially manufactured dog foods, there are those made specially for large- or giant breeds. It is important to choose the right dog food for his large size so that you can be sure he gets the right amount of nutrients in for him to grow strong and healthy.
If you aren't sure about what food would most benefit your Great Dane, ask your vet. While it is important to also feed him quality home-made food and raw meat, when buying kibble for him,check the label of the food you buy him and make sure that the concentration of protein isn’t more than 23 to 25%.
Remember to provide him with a constant supply of fresh, cool water.
Brush your Great Dane’s coat at least twice a week. He has a short, smooth coat so it will be easy, and the brushing will keep his coat soft and shiny. Use this time to also check for fleas and ticks or lumps. You will also need to check his nails and trim them if they don’t trim down on their own.
Your Great Dane will need to be exercised every day if you want him to maintain his lean, muscular shape. It keeps him happy too. He isn’t the kind of dog though that you want to turn into your running partner when you go jogging or cycling. He can go on a walk and play in the garden, but the exercising shouldn’t be for long periods of time.
Every puppy needs to get to the vet for his first check-up when he is 6 weeks of age, and your Dane will also have to. As a puppy he will need to be de-wormed which will happen with this 6 week check up. He will also be vaccinated for distemper.
