Pugnaces Britanniae vs Japanese Terrier - Breed Comparison

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.

The Japanese Terrier is native to Japan and is a rare pure bred dog. It is believed that the dog comes from Smooth Fox Terriers who arrived way back in the 17th century.

Certainly he looks very much like a regular Fox Terrier. It is thought that these smooth Fox Terriers were then interbred with local, Japanese dogs and used to hunt rats. Gradually he became a lap dog and companion.

Planned breeding of the dog began in 1920, and it was in 1930 that the dog was admitted to the Japanese Kennel Club with a breeding program being started.

Today you will find the Japanese Terrier in his home country and small numbers elsewhere. He was admitted to the United Kennel Club in 2006.

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.

The Japanese Terrier is a small sized dog who stands at 20 – 33cm at the shoulders and weighs in at about 2 to 5kg.

He is a short, smooth haired dog with a tight skin and in colors of white and black. Sometimes you may find a little bit of tan color on the face too as well as 'freckles' around the neck area and legs. The black shading of the coat is essentially found around the head of the dog and also his ears.

His ears are set high on the head and are semi-erect, semi-floppy. The tail has always been traditionally docked, giving the dog a nice compact look but these days it is unfortunately often left long and then its a medium length tail which is thinly covered in short hair. The nose is black and the eye are brown, bright and alert.

Temperament:

Gentle, cheerful, intelligent, loving and loyal are some of the characteristics of the Japanese Terrier. People who have kept him as a pet will vouch for him being a wonderful companion.

He is an active dog, but he still loves to be petted and won’t do well if left alone and not part of his human family. Being a clever dog, he is easy to train, learning easily and quickly. He is quite amusing at times and you can even teach him some tricks.

He gets on well with other pets in the home as well as with children. He is alert and will make a good watchdog, alerting you to an intruder.

Because of the Japanese Terrier’s small size and sensitive nature, this breed needs a calm owner and a quiet household. It is not recommended for boisterous households.

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.

As a pet of yours, the Japanese Terrier is an animated, contented little dog. He loves playing games and gets on well with children who aren't rough and disrespectful of him.

He is smart and gentle and loves nothing more than to sit on your lap in the evenings and be your reading- or watching-TV companion. Give him the right amount of attention as any other family member receives and he is guaranteed to make you an excellent, low maintenance pet.

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 Japanese Terrier has no particular health issues and has a lifespan of 12 – 15 years if looked after well.

There are always one or two illnesses to watch out for such as eye- and ear infections. Some dogs also develop conditions such as Patella Luxation. This happens when your dog's kneecap is dislocated. It can only be returned to its normal position when certain muscles in the back legs are relaxed and lengthened.

With this condition, your dog holds up one of his hind legs. This condition is more prevalent in small dog breeds.

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.

The Japanese Terrier is an active dog and will require exercise every day. He’ll love to join you on your walks or have ball games in your garden. He can adapt to life in the city or in the country but will always need to have good exercise.

Grooming:

The Japanese Terrier is a medium shedder and you want to be sure then to brush him twice a week to get rid of all those loose hairs.

Diet:

The Japanese Terriers will require the best commercially manufactured dog food, and instead of one large meal a day, rather feed him 2 smaller meals. You can mix some tasty home-made food into his dry kibble from time to time. Excellent home-made food would be something like cooked chicken, brown rice or pasta and some vegetables.

If you can, try to also include some raw meat occasionally. If you’re in any doubt as to how to feed your Japanese Terrier so that he remains healthy, speak to your veterinarian.

Your dog should never ever be without a continuous supply of fresh, cool drinking water.
