Korean Mastiff vs Greek Sheepdog - Breed Comparison

Known as the Olympus Dog or even simply as the Greek Shepherd, the Greek Sheepdog is a large to giant molosser dog from Greece. His purpose has always been to guard flocks and livestock from predators and he has been around for hundreds of years, looking much like the Great Pyrenees.

It is believed that the dog was likely bred with a number of breeds – both local and non-local dogs.

Unfortunately there were no records kept of the development of the breed but today the Greek Sheepdog remains a rare and fairly unknown breed outside of Greece.

It's numbers are dwindling in Greece too and since 1998 the Greek ARCTUROS has made attempts to save the breed, starting the Greek Shepherd Dog Breeding Program.

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 Greek Sheepdog is a large dog, standing at 65 – 75cm and weighing roughly between 32 to 50kg. He is a dog that displays physical strength. He has a large head with brown eyes and a serious expression on his face. He has a thick double coat which is essentially white with red, black or brown markings.

Temperament:

Maybe because of his size and him being a strong-willed, independent thinker, the Greek Shepherd may not be the best choice for a first time dog owner. Having said that, if you're a strong, firm, patient, kind person, then you'll be able to raise any kind of dog, first time or not.

The Greek Shepherd is a brave, loyal, calm, protective dog and with socialization and training, can make an awesome pet. They are dogs who are a bit suspicious with strangers, not making friends too easily. He loves his human family and wants to be part of their activities. He can't be left on his own day after day as this can lead to excessive barking and destructive behavior.

They've been dogs used to working with livestock and they will certainly need to be taken on daily walks and involved in rough and tumble games as they thrive on activity. The dog won't fit easily into city life where there is just a handkerchief-sized garden as he needs space and activity.

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.

With good care and lots of love, this dog can live to be between 10 to 12 years of age. He is unlikely to get sick very often, but still it it wise to know of some of the health issues than can occur with large breed dogs like this.

Some diseases to look out for include -

Dilated cardiomyopathy:

This is a disease of the heart muscle. The heart is enlarged and unable to have the right heart rhythm. The distended muscle isn't able to push the blood through the heart chambers to where it is needed. Cause for this dilated heart can be genetic, nutritional, infectious or metabolic.

Because taurine and carnitine are involved in good heart function, and low levels of these amino acids can cause symptoms of dilated cardiomyopathy, supplementation is useful, especially if you feel your dog isn't getting in the right kind of food.

Lyme Disease:

Borreliosis, a bacterial infection, causes Lyme disease, transmitted by the Ixodes tick. The tick bites the dog and the toxins gets into the dog's bloodstream, with the bacteria travelling to different parts of the body.

Typical symptoms in a dog includes loss of appetite, fever, no energy, swelling of joints and lameness, but symptoms can progress to kidney failure too or cardiac problems. Treatment will include antibiotics.

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.

Grooming:

The coat of the Greek Shepherd is fairly long so it will need to be brushed at least twice a week to keep it free from matting and tangling. He is an average shedder and the brushing will remove all loose hairs, keeping the coat sleek and shiny.

Diet:

Feeding your Greek Sheepdog requires giving him top quality food as this will ensure he is healthy and can ward off common dog illnesses. If you're going to be feeding him kibble, make sure to go for the top quality brands, and as a treat for your pet you can add in some brown rice, pasta, brown bread, cooked chicken and vegetables.

Dogs are essentially carnivores and he will need to have some raw meat such as beef added into his kibble from time to time. He should never ever be without a constant supply of fresh, cool water.

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.
