Korean Mastiff 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.

This large breed dog is also known as the Mee Kyun Dosa. In spite of his huge size, he isn’t aggressive at all and is bred to be a companion dog.

He was originally developed to be a working dog. The dog was developed in the late 1800’s from European and Asian working breeds. Those interested in dog breeds suspected that a crossing of the Japanese Tosa-Inu with the Neapolitan Mastiff and the Dogue de Bordeaux brought about the breed. They also thought that the Saint Bernard and English Mastiff were brought in later on as well.

These large molosser dogs have been developed through years of inbreeding. It is one of the biggest dogs in Korea.

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.

You can’t help but stare at the Korean Mastiff because of his strong, muscular neck of loose skin that forms dewlaps. His face is wrinkled and he has a cumbersome, sluggish gait.

He is a large dog standing at anything between 59 to 76cm in height, both male and female. He can weigh between 65 to 74kg. He is noticeable because of his fairly loose fitting coat, which is short and smooth and which is a rich, shiny reddish, orange or brown colour.

The nose of the dog is broad and dark, the ears soft and floppy and he has eyes which are set wide apart.

Temperament:

The Korean Mastiff is reserved with strangers but he is friendly and even tempered with his human family, making an ideal pet.

He is looked upon as a gentle giant, being an oversized playmate for children and he also tolerates other pets in the home.

He isn't an overly energetic dog, but that doesn't mean he shouldn't be exercised. He will need long walks to avoid him putting on weight.

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.

Your huge Korean Mastiff is a good natured dog who isn’t aggressive. He loves being with his human family and makes a particularly good pet when he has been trained and socialized.

He likes a firm but fair owner who takes a leader-of-the-pack role. In spite of his largeness and sluggishness, he can be quite agile and makes a good watchdog too.

All round, the Korean Mastiff, known as a gentle giant, is capable of making you a splendidly friendly, loving canine companion.

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.

Treat your big Mastiff dog like the wonderful fur-child he is and make sure your attend to all his medical needs to avoid pain and discomfort for him.

Cherry Eye:

Cherry eye is a fairly common health issue with this breed. It affects the tear gland of the third eyelid, and if left untreated, can lead to ongoing eye problems.

All dogs have a third eyelid, as well as two tear producing glands to lubricate the eyes. Its an important protective component to eye health in dogs. When the connective tissue that holds the gland in place is damaged or weak, there is a red protrusion of the gland from the lower eye. This is a congenital disorder. Don’t ignore it, but get your pet to the vet so you can catch it early.

Bloat:

Canine bloat, known as gastric dilatation and volvulus can be a killer disease for your pet, more so with deep-chested, large breeds.

Gas accumulation is known as bloat, and its the accumulation of gas which can cause the stomach to rotate. A dog can go into shock from bloat. The reason for this is that the stomach expands, putting pressure on veins. Blood can’t flow as it should and the blood supply gets cut off to the stomach.

Your dog could be vomiting, restless, the stomach hard and bloated or he may be drooling. Dogs who gobble their food down and eat just one large meal a day have an increased susceptibility to GDV than other dogs.

The wrong ingredients of a dog’s diet can also contribute to bloat. High quality food and feeding your pet smaller meals can help.

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.

Grooming:

A Korean Mastiff is an easy dog to groom with his short smooth coat. He is a moderate shedder so a brush twice a week will be sufficient to maintain the shiny, smooth condition of his coat.

Because the dog has lots of skin and folds, these folds will need to be washed and kept clean as grime can collect.

While you're busy attending to his skin check his nails too and check inside and outside his ears for signs of redness and irritation.

Diet:

Puppies use up more energy than mature adults, requiring a diet of good quality protein. Dogs that have been spayed or neutered will require less calories as will senior dogs.

Korean Mastiffs require high quality nutrition, and if its dry kibble, make sure its the best brand. Mix in some home-made food such as cooked chicken, brown rice and vegetables from time to time as well as some raw meat occasionally.

Protein and fat from good sources are top ingredients for your Korean Mastiff. Avoid food with allergens such as corn and wheat, sweeteners, preservatives and colorants.

Make sure your large pet has constant access to fresh water.
