History

japanese chin - historyThe Japanese Chin, also known as the Japanese Spaniel, has always been known for thousands of years as a dog with strong companion characteristics.

Hailing from Asia, he is also known as the Japanese Spaniel. In Japan, the Chin dogs are royalty and lapdogs, and while the exact origin of the Japanese Chin isn't quite clear, it is an ancient toy breed.

The first Japanese Chin was brought to America in 1882. The toy breed was recognized by the American Kennel Club in 1888, as a Japanese Spaniel. The AKC changed the breed name to the Japanese Chin in 1977.

Based on the massive dog of Mesopotamia in 5000 BC, the American Molossus is the same dog recreated in the United States by and for the lovers of these giant dogs. The ancient Molossus was fierce to look at, massive in size, courageous and loyal. He was undaunted by any animal and stood up to any man attempting to hurt his master. When Rome fell the descendants of today’s Molossus were scattered and attempts to revive the breed have created carious large dogs. The American Molossus is the first true recreation that hits the mark.

The original Molossus was one of the most primitive of dogs, one of the earliest dogs that men domesticated. Their initials duties were the guarding of herds and homes against all enemies. They were incredibly loyal to their one master and stayed with him and protected him. These dogs also ate carrion and served the villages by eliminating animal carcasses. They could handle any other hunting animals such as wolves and large cats. This dog, although extinct was the ancestor of all the Mastiff-type dogs of today. The Molossus is said to be the ancestor of the St. Bernard, English Mastiff, Greater Swiss Mountain Dog, Bernese Mountain Dog, Newfoundland, Great Dane, Great Pyrenees, Rottweiler, Rottweiler and the Neapolitan Mastiff. Now these breeds have become the ancestry of the American Molossus.

According to Marcus Curtis, the founder of the new Molossus, the nearest relative of the American Molossus is the Neapolitan Mastiff. The Hines Bulldog, German Rottweiler, American Bandogge, and South African Boerboel together with the Neapolitan Mastiff were used to form the American Molossus. The goal of the founder was to make a great family pet and protector. It was specifically bred to be courageous, loyal and protective.

Health Problems

japanese chin puppies - health problemsThere are a few health issues with your Japanese Chin that are worth knowing about such as hypoglycemia, cataracts and heart murmurs. Allergies and dental issues also need to be checked.

Dog breeds with the flattened face always battle with dental-, eye and breathing problems. With good care however, your Japanese Chin can reach anything from 10 – 12 years of age.

Heart Murmurs:

Murmurs come about because of a disturbance in the blood flow and which can produce an audible noise. If your dog's murmur is associated with structural heart disease, your dog may display signs of congestive heart failure and he'll be weak for instance and be coughing.

When your dog gets to the vet, the course of treatment will be determined on the type of heart murmur. Luckily puppies with low grade murmurs often grow out of it but if you have an adult dog, routine diagnostic imaging may be recommended by your vet.

Like all Mastiffs the American Molossus faces a variety of potential illnesses, some brought on by its size, some not.

Spondylosis

This could easily be a function of its massive size. It is a degenerative disease and can cause the dog to become lame. In many cases the vertebrae can fuse, or severe pain can result. This is mostly seen in older members of the breed.

Cystinuria

Male Molossus can contract this inherited metabolic disease primarily. It can be life threatening and very serious as it affects the kidney and the bladder.

Wobblers Syndrome

This is essentially Cervical Vertebral Instability (CVI) and is caused by the pressure of the nerves in the neck and cervical spinal cord. This compression can cause deformity, pain and abnormal stance/gait. IT has been attributed to the nutrition needs and rapid growth of the Mastiff breeds.

Like all giant Mastiff breeds the Molossus can have skin issues from the wrinkles, dysplasia in the joints which we will address below.

Caring The Pet

Grooming:

japanese chin dogs - caringThe Japanese Chin has a single coat, and a brush once or twice a week will keep the coat silky and untangled.

Check his ears for dirt and wax and try to wipe inside the ears, being very, very careful not to go deep into the ear to avoid damage.

Clip his nails and brush his teeth as small dogs are more prone to dental disease. Periodontal disease is preventable with dental cleaning. Dental disease starts when plaque sticks to the surface of the teeth. It hardens, spreads under the gum line and cause tissue damage. It also damages the immune system.

Exercise:

The Japanese Chin is an energetic dog and loves a game and a walk. It isn't the kind of dog that you will take on your hikes or swimming as it tends to huff and puff after a while from too much exercise, and more specifically in hot weather.

Diet:

Dog experts say that a grain-free food is best for this kind of dog. Kibble which comes with lean protein and with plenty of vitamins and minerals such as taurine and carnitine is recommended. They are good for the joints, coat, heart and eyes. Japanese Chins can be prone to heart- and eye problems and kibble rich in omega 3 fatty acids will be good for the Chin for many excellent reasons.

If you're in any way uncertain about what to feed your Japanese Chin, speak to your vet as the type of food you feed your pet will determine how healthy he will be. Always ensure he has access to fresh, cool water.

Feeding

Remembering that this is a very, very large dog you need to be careful about nutrition and how fast your puppy will grow. American Molossus puppies need four meals a day until 12 weeks old. Then until they are 6 months old feed then 3 times a day. Finally, from 6-month-old puppy to adult – feed them twice in 24 hours.

At one year either feed them once or two small meals.

Many people feed their Molossus eggs, vegetables, fruit, and cottage cheese as ten 5 of the total for the day but avoid other table foods. The Molossus can become very picky about what he eats if you feed him too many table scraps.

Health issues

In addition to the health problems listed above, the American Molossus is also susceptible to: Ditichiasis – Eyelashes that are in the margin of the eyelids and can cause eye irritation. May require surgery to correct.

Cataract

Could cause blindness if not removed. Ectropian/Entropion: Eversion and inversion of eyelids which cause ocular irritation.

PRA or Progressive Retinal Atrophy

This is a degenerative disease which causes the dog to go blind. It is a disease the affects the retinal visual cells, first causing night blindness then day blindness. A DNA test is available for detecting PRA in all Mastiff breeds.

Dysplasia of the Elbow or/and the Hip

Common in large breeds and especially in giant breeds like the Molossus. Multiple forms and causes but all can cause pain and lameness.

Skin issues

Do to wrinkles and loose skin – check often for moisture and infections.

Panosteitis or Wandering Lameness

The is a problem based on a variety of possible causes. It happens when the puppy is between 6-16 months of age. Lameness occurs over time in one limb or in all. It can be intermittent and might be caused by diet, genetics, stress, autoimmune or metabolic issues or infection.

HOD or Hypertrophic Osteodystrophy

This issue is developmental as the dog’s toes turn either inward or outward, then as the condition advances the dog suffers fever, pain in all joints, lethargy and the inability to stand. This happens when the dog consumes too many calories for his activity level in the development times.

Exercise and games

The American Molossus is not a couch potato. He needs to be walked at least twice a day and loves to play fetch. He will be greatly benefited by obedience training. Do not overdo it with exercise but make sure they don’t just lay around.
