American Mastiff may have less litter size than Pugnaces Britanniae. Both American Mastiff and Pugnaces Britanniae 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.
Pugnaces Britanniae is a dog which is now extinct. There isn't certainty surrounding the origins of the dog but it is thought they descended from dogs brought to Britain way back in the 6th century BC already.
These are ancient dogs, and when you do research you find references dating back to centuries ago. In fact when you read of the Roman conquest of Britain you read of huge dogs, which the Romans referred to as Pugnaces Britanniae.
It is believed that the English Mastiff descended from the ancient Alaunt and Pugnaces Britanniae and that the dog was used as a war dog.
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 Pugnaces Britanniae was a huge dog standing at roughly 67 to 75cm and weighing 52 to 110kg.
He was a heavily built dog, a Mastiff type dog that had a large head, broad muzzle with fairly loose skin around the mouth, brown eyes, a broad back and rump, muscular legs and floppy ears with a long tail. In fact the Mastiff, thought to have descended from the ancient Alaunt and Pugnaces Britanniae, gives you an idea of what the dog looked like. He no doubt has a short, smooth coat available in fawn, tan or brindle and with the black mask.
The Pugnaces Britannia was a naturally aggressive dog so it is to be expected that he wouldn’t automatically have been a good family dog, possibly being aggressive around children and other dogs. They were intelligent and were no doubt taught some simple commands.
They were also very territorial dogs, wanting to instinctively chase and attack unknown people and animals. They were strong minded, confident, loyal ad loving dogs towards their owners, being protective of them, wanting to please them.
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 Pugnaces Britanniae may well have been a large dog and quite imposing to look at but he was in all likelihood a good-natured pet who got on well with his family members, being loyal and loving if brought up correctly.
Long ago dog training and socialization didn’t exist but a large dog like this would have to be socialized and trained to become obedient and an amicable all-rounder.
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 Pugnaces Britanniae could live to 10, 11 or 12 years of age with good care. Large Mastiff type dogs like this would have had to watch out for common canine diseases such as hip dysplasia, cancer and bloat.
In those days, no screening tests were available for health problems like this. Gastric dilatation volvulus or bloat is a common health issue with large, deep chested dogs where the stomach fills with gas and the stomach twists. Its a life threatening disease.
Canine heart disease is another serious health issue with these mastiff type dogs. Early stages with heart disease show there may well be no symptoms at all. However, as the heart disease progresses towards congestive heart failure, the dog will have symptoms such as fatigue, difficulty with breathing, weight loss, a distended abdomen and coughing.
A dog with symptoms like this would have to see a vet immediately.
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 diets of ancient dogs were different to what they are today, as in those days there were no commercially manufactured dog foods. Dog owners in all likelihood tossed scraps to them which included starch.
Today a large dog such as the extinct Pugnaces Britannia would have no doubt been fed a high quality kibble from a leading brand and packed with minerals and vitamins specially formulated for a large dog breed.
Homemade food is also important, but not any kind of food – it has to be food which doesn’t upset the dog’s digestive system. Simple but nutritious food such as boiled chicken, brown rice or pasta, sweet potatoes, carrots and spinach is ideal for a dog, and when it is chopped up can be added twice a week to the dry kibble for a tasty, healthy treat.
Raw meat added in occasionally is also hugely beneficial. No dog should ever be without fresh, cool water constantly available.
As a short haired dog, the Pugnaces Britanniae would have required a brushing twice a week to rid the dog of loose hairs. Maybe in those days they didn’t check their dogs over to see that all was well, but today you would need to check the inside of the ears. If the insides were red, it could be a sign of an ear infection brought on by dampness, excess wax and dirt.
The eyes would need to be checked for discharge and the teeth checked a well. One rotten tooth can cause a lot of havoc. The nails of the dog would have had to be checked and clipped as well.
As a war dog, the Pugnaces Britanniae would have been fit. He is a big dog and while they require exercise such as walks and hide-and-seek type of games, he isn’t the kind of dog that would go running with you on a jog, as large, heavy dogs can overheat easily.
