History

sealyham terrier - historyThe Sealyham Terrier is a rare dog breed originating in Wales. The dog was developed in the 19th century by Captain John Edwardes at Sealyham House. The Sealy has been associated with members of the British Royal Family, but its numbers declined to such an extent that it was listed as a vulnerable native breed by the Kennel Club.

The Sealyham Terrier club was created in 1908 and the dog breed was officially recognised by the Kennel Club in 1911. This dog is now recognized by all the major kennel clubs. The American Sealyham Terrier Club was founded in 1913.

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.

Description

sealyham terrier puppy - descriptionThe Sealyham is a dog that stands low to the ground and its height shouldn’t exceed 27 - 30cm and weight should be about 8 - 9kg.

The double coat is considered non-shedding and is wiry and weather resistant. It is nearly always white but can be fawn. They’ve got big heads with dark, deep set eyes. The ears are semi-erect, semi-floppy and the tail is usually docked.

Temperament:

Affectionately referred to as Sealy, there aren't too many of these little dogs left. At one time, they were a very popular terrier breed, but today they are uncommon – almost endangered.

He’s a social dog with his human family but tends to be reserved around strangers. He also tends to be just a little bit more mellow than some of the more rowdier terrier breeds.

He gets on well with other dogs in the home as well as with children. He is an intelligent little dog but is inclined to be stubborn so you have to show him both firmness and kindness and also think about obedience training for him.

He’s amicable and adjusts well to life in the city or the countryside.

This is a giant, massive dog in every way and this recently developed standard makes that very clear. The Molossus should be heavy bones, muscular with a lot of loose skin and wrinkles of all kinds, everywhere. He is an intimidating presence, with a massive square head, broad shoulders, height and mass. No, the American Molossus is not athletic, but he certainly is intimidating.

His head is massive in comparison to his body and it must be square. He has extensive wrinkles and pendulous lips and dewlap. The face is all folds of skin and wrinkles. Deep set eyes, drooping upper lids and lower lids as well as an intimidating expression. His brow is well developed with a marked frontal furrow. The nose is large, and the muzzle is about a third of the length of its head. It is short and broad. Everything about the head must be square. It’s neck and body are powerful and muscular. The chest is deep, wide and barrel like. The back is also powerful and muscular. The front legs are heavy and muscular while the hind legs are broad, strong, powerful and wide-stance. Do not remove the front dew claws. His tail is thick and wide then gradually tapers at the tip.

Characteristics

sealyham terrier dog - characteristicsThe Sealyham Terrier is such a robust little dog with a distinctive look.

He can be stubborn but he loves his human family and is sociable and amicable with them, slotting in to their way of life. He can be a couch potato or an active outdoor dog – whatever is required of him and he makes and excellent, loving family pet and companion.

The American Molossus is an intimidating massive giant bred for protection and guard duty. He is incredibly loyal to his family and courageous in his protection of them. They are guard dogs, not attack dogs. Their simple appearance is usually enough to frighten off anyone intending harm on their families. He is in reality a loving giant. He is intelligent and stable with a strong desire to please his owner. He is a calm yet vigilant presence in the home.

Because the Molossus is so large, it is recommended that the puppy be socialized and trained professionally. It takes a strong owner to handle this breed. They need to know the rules and have the rules consistently applied. The owner must be the pack leader.

Health Problems

sealyham terrier puppies - health problemsThis is a hardy dog breed and you don’t hear of many health problems associated with him. It seems as though you might have to watch out for an eye condition known as lens luxation. It's an eye condition with dogs where the lens slips out of position because of weakening of the fibers that hold it in place.

There is a lack of fluid in the eye causing optic nerve damage and this can lead to blindness.

Retinal Dysplasia is another eye problem . This is a developmental malformation of the retina that the dog is born with. Symptoms in dogs are a reluctance to jump off things such as the bed or he may even bump into things.

Atopic Dermatitis is something the Sealyham is more prone to. Its an allergic skin disease which drives a dog mad with its itchiness. Your pet will certainly need treatment from the vet to relieve it.

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

sealyham terrier dogs - caringProvide your Sealy with his own warm, dry bed.

Brush the long, weather-resistant coat at least twice a week. Hand-stripping of the coat will maintain the wiry, hard texture, but because this method can be quite a laborious process, many Sealy owners rather have their dog professionally clipped.

Check inside his mouth for bad teeth as well as inside the ears for signs of infection. His eyes should also be clear and free of discharge.

His nails will also need to be trimmed.

The Sealyham doesn’t require a lot of exercise but he must at least be given a walk every day.

Ensure the vaccines are up to date. They start when your pet is just a puppy. Remember to get your dog to the vet when you suspect that he is ill.

Feed your Sealyham with good food. Make sure you’re feeding your pet a high quality food as this promotes health and longevity. Provide your Santal Hound with top quality food to ensure his health.

Always choose the quality commercially manufactured foods on the market – those that have natural, good ingredients in them. Try to include some home-made food for him which can be simply mixed into the dry kibble twice a week.

There is no need to offer your dog a host of different foods. Dogs want simplicity and consistency. Boiled chicken, brown rice or pasta and spinach, sweet potatoes and carrots is super tasty and nutritious. If you can, also try and include a little bit of raw meat to his diet occasionally as this can go towards ensuring he doesn’t get skin diseases.

Make sure that a constant supply of fresh, cool water is available to your dog.

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.
