History

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.

ryukyu inuThe Ryukyu Inu is a medium-sized dog that comes from Okinawa, Japan.

It’s a dog that is fairly rare having been used to track boar. There isn’t much information on the dog’s history but after its numbers declined after World War II, there was an urge in the 1980s to save the breed.

The dog isn’t recognized by any major Kennel Clubs.

Description

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.

Temperament:

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.

ryukyu inu puppy - descriptionJapanese dog breeds end with the word ‘Inu’ or ‘Ken’ . It means ‘dog’.

The medium sized Ryukyu Inu stands at between 46 to 50cm in height and weighs between 15 to 25kg. He has a black nose, dark brown eyes and erect ears. The tail is long and curls over the back.

The dog’s coat is short and you get the single- and double coated varieties. The coat can be brindle, red, white, liver or black. Some of the dogs have tiger-like stripes in the coat. People are amazed at these dogs as they have incredible climbing abilities and are even capable of climbing a tree.

Temperament:

These dogs are quiet, unobtrusive dogs. The Ryukyu Inu looks very much like a wild dog, which gives the impression of being un-trainable and ferocious but they are easily trained and make splendid pets.

Many people who have had them as pets say they would choose this dog over and over again. They are brave too and get on well with children or pets in the home. They don’t look for trouble, and their kind, stable natures make them excellent therapy dogs.

They’re intelligent dogs and will require plenty of mental and physical stimulation. They will also need to be trained and socialized as they are confident, strong-willed dogs who might not obey you if left to do what they want.

Characteristics

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.

ryukyu inu dog - characteristicsThis dog has always been a hunting dog so he will want to have his fair share of good exercise – long walks as well as ball and rope games.

He makes a splendid pet because he has an amicable nature wanting to please. He is quiet, loving and loyal, and with such a dog in your home and heart, you just keep discovering what a wonderful pet this 4-legged friend can be.

Health Problems

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.

The Ryukyu Inu, with its 10 to 12 years lifespan, will be prone to minor ailments, but with good care he is not likely to succumb to any of them.

Cataract:

Cataracts have a number of causes in dogs. This disease of the eye can occur at any age, and can develop over weeks or even years.

Cataracts can occur in just one eye or both eyes and a disease such as diabetes can bring on a cataract.

Good nutrition is important for a dog to build a strong immune system, and nutritional supplementation can certainly help to enhance lens health. Cataract surgery can be performed to remove the cataracts.

Caring The Pet

Diet:

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.

Grooming:

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.

Exercise:

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.

ryukyu inu dogs - caringThe coat of the Ryukya Inu requires brushing twice a week to remove loose hairs. At the same time check your dog over for new lumps and check inside his mouth for bad teeth. Bad teeth can cause lots of pain and toxins within the body. You can also choose to have the teeth seen to and cleaned by your vet.

Provide him with his own warm, dry place to sleep.

Provide him with top quality food. There are some excellent commercially manufactured foods on the market that make a point of ensuring good ingredients in them. Your Ryukya Inu needs good food to ensure longevity and health.

Try to include some home-made food for him which can be simply mixed into the dry kibble twice a week. Boiled chicken, brown rice or pasta and spinach, sweet potatoes and carrots is super tasty and nutritious. This food can all be chopped up, refrigerated and added warmed up and in small portions to your pets dry kibble once or twice a week. Your dog will love it.

Ensure there is always a bowl of fresh, cool water within his reach.

Have him neutered or spayed if you aren’t wanting puppies.

Keep his vaccines up to date against some deadly canine diseases.

Get him to the vet when he is injured, in pain or sick.
