Kai Ken vs Jug - Breed Comparison | Petzlover

The Jug is a crossbreed – a mix of a pug and a Jack Russell Terrier and they were bred in England with the idea to keep the basic features of a pug but just with a longer nose.

Details on the origin of the dog are not altogether clear but the dog was developed so that it would reduce the breathing problems that pugs and other flat-faced breeds are known for.

This isn’t an old breed and development started around the 1960s. It is one of the most recent breeds to be registered by the American Canine Hybrid Club.

The Kai Ken dog hails from Japan and is both an ancient and rare dog. In fact the dog was discovered in 1929 in the Kai province near Mount Fuji. The dog has the nickname Tora Inu in Japan which means 'Tiger Dog'. Maybe its got to do with the brindle striped coat or his bravery.

He falls into the working class category. In 1931, the Kai Ken Aigokai registry was formed to preserve the dog. In fact in this year Dasuke Adachi discovered these dogs and in 1934 was actually designated a Natural Monument in Japan and also protected by law.

The Kai Ken was recognized in 1934 by the Japanese Kennel Club. It is not 100% certain but it is thought that the dog was brought to the United States in the 1950s.

The Jug will usually end up having a round head with the typical short muzzle of the Pug. He may be somewhat lighter in build than the Pug, taking more after the Jack Russell in this regard.

The way the dog turns out will depend on which dog the puppy takes after. He is a small breed dog standing at between 25 to 36cm at the withers and weighing 5 to 7kg.

When it comes to coat color you'll find they can vary between fawn, black, apricot and sometimes a blend of two colors. While pugs come with smoothish coats, the Jack Russell can either have a smooth or rough coat and your Jug could inherit either a smooth or rough coat.

He could inherit the Pug’s flat, somewhat wrinkled face while others may have a slightly longer muzzle. The eyes are large and the ears are floppy. The legs are short and the tail will no doubt be left long these days and be slightly curled.

Temperament:

The tenacious, fearless, intelligent nature of the Jack Russell Terrier mixed with the entertaining, amicable nature of the pug has brought out the Jug dog with a whole lot of excellent qualities of both dog breeds.

They are loving, loyal dogs and when they are trained and socialized they get on particularly well with both pets and children in the the home. He is intelligent and will be able to learn some simple commands such as sit, stay and lie down.

The Kai Ken has always been used for hunting purposes. He comes as recommended for hunting people and those who are active.

It is a medium sized dog standing at between 43 to 56cm in height both male and female and weighing between 14 and 22kg.

The ears of the dog are erect, the muzzle is fairly tapered and the nose is black. The tail is bushy like that of a fox and curls over the back. The double coat of the dog is of medium length and harsh and is a brindle color in a reddish or black shade.

Puppies are born black and then the brindle stripe-like pattern comes in later. He has an athletic body and is a keen swimmer.

Temperament:

The Kai Ken is an intelligent dog, loyal to his human family while being somewhat reserved around strangers. They are amicable with both children in the home as well as other pets.

He is a friendly, intelligent dog, forming close bonds with his family. Have him trained and socialized and he'll make you a splendid pet who will be willing to guard you if anyone threatens.

One look at that bright face and you can see that he is an intelligent, independent dog. He is also courageous and fearless and makes a great watchdog, especially because he is naturally reserved and suspicious with strangers.

Jugs are wonderful little dogs and they make a good choice for first time dog owners as they don’t come with any difficult characteristics.

They’re playful, intelligent, energetic and amicable and just love to please their human family. Because of his small size, he is also an adaptable dog, being able to settle down in the city or the country, as long as he is given enough mental- and physical exercise to prevent boredom and frustration.

Provide the right environment for your Jug and you’ve got an awesome canine friend for life.

The Kai Ken is a working- and hunting dog, so he is used to being active and will want a home where he can be played with and exercised regularly.

He can be slightly stubborn and independent so training and socialization are imperative. This is also because the dog’s curiosity and his athletic skills can lead to trouble if he isn’t properly trained.

Treat him the way he deserves and you’ll see that he is able to develop a strong bond with you and be altogether an excellent family pet.

Your jaunty little Jug can live anything from 12 to 20 years when looked after well.

Just like with any other dog however, he can become ill, and then you will need to get him to the vet as soon as possible. Allergies, breathing problems, bloat, primary lens luxation, skin disorders, deafness, cardiomyopathy and obesity are just some of the common dog diseases that your Jug might have to deal with.

Breathing Problems:

Because one of the dogs used in the development of the Jug is a Pug, as a brachycephalic breed, they could suffer with breathing problems. The Jug which inherits the shorter muzzles can suffer from a condition known as Brachycephalic Airway Syndrome.

Eye Problems:

Some Jugs can have the large, protruding or bulbous eyes of the Pug. With an eye problem known as Entropion, the lid of the eye can turn inward so that the eyelash pushes into the eyeball, causing lots of redness, discharge and irritation. This can lead to an infection in the eye. You may notice your Jug constantly pawing at his eye.

Obesity:

This can be a real problem for your Jug and the extra weight will put additional strain on the dog’s heart and other organs and also affect his overall health and wellbeing.

With a lifespan of 14 to 16 years, and given the genetic purity of the Kai Ken, you aren't likely to battle with congenital health problems with your dog, but it is always good to be aware of certain minor health issues that he could succumb to.

He can suffer from a few common dog diseases such as progressive retinal atrophy or hip dysplasia.

Progressive Retinal Atrophy:

This is a disease of the eye where there is wasting of certain parts, and in this case the cells of the retina develop abnormally. This can eventually lead to blindness. It’s an inherited disease that can occur in pure- and mixed breeds, and dogs with PRA shouldn’t be used for breeding.

It isn’t a painful condition, and the first symptom usually noticed in a dog is night blindness where you may notice him bumping into things at night and being reluctant to walk around in the dark.

Exercise:

Small he may be, but the Jug is an energetic little dog who will require exercising to keep him content. Toys to chew on are good and you can take him for walks too. Throw a ball for him or let him tug on a rope.

Diet:

To keep your little Jug healthy and happy, you want to be sure that his diet is made up of a balanced mix of vitamins and minerals. If you feed him a commercially manufactured food, make sure that its one of the best ones free of toxic colorants and preservatives.

Check on the packaging for portion sizes for your pet. Give him some home-made food too such as cooked chicken, rice, pasta and vegetables and try to also include some raw meat mixed into his kibble from time to time. Fresh, cool water should always be included day and night.

With healthy food, your Jug can make it to 17, 18, 19 or 20 years of age even. Remember that anytime you get a pet, you can check with your veterinarian for dietary recommendations.

Grooming:

The Jug can shed quite a bit, particularly if he inherited more of the Pug coat. Make sure you brush his coat at least twice a week to rid him of loose hairs. Brushing also strengthens the bond between you and your pet.

General:

Recognize the signs of an ear problem. These can be redness or swelling, ear scratching, head shaking or ear discharge.

To keep his teeth and gums healthy you can provide him with safe, appropriate toys to chew on as well as dental chews recommended by your vet.

Check your dog’s eye health. Signs of an eye problem are eye discharge and redness. Take your pet to the vet as soon as possible and try and remove hair around the eye that could be causing irritation.

Even though the coat is thick, the Kai Ken will require basic canine care, so a brush twice a week will be enough to keep the coat free of loose hair. He sheds more heavily a couple of times a year and then he will require more brushing.

He has always been used to hunt so he is a dog that will require regular exercise such as walks, hikes, swimming and ball games.

The nails of the dog should be trimmed regularly once they become long as long nails can be hazardous and can hook onto things, causing injury to the nail area.

The ears of the dog should be checked regularly for fleas and ticks, and teeth should also be brushed with canine toothbrush and toothpaste.
