History

glen of imaal terrier - historyHailing from Ireland and known also as the Wicklow Terrier or just Glen, the Glen of Imaal Terrier was used to get rid of rats, badgers and otters as well as being a good all-round farm dog.

Using his strength, he was good at digging into burrows to root out badgers, but unlike other terriers, he wouldn’t go on and on yapping around his prey. He isn’t an excessive barker.

The terrier was recognised by the Irish Kennel Club in 1934 and later by the American Kennel Club in 2004. The Canadian Kennel Club recognized Glens in 2017.

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.

Characteristics

glen of imaal terrier dog - characteristicsThe Glen of Ismaal Terrier is more docile than other terrier breeds, but that doesn’t mean he isn’t feisty. He loves to play and is an adventurous dog, always on the lookout for exciting opportunities and to chase prey.

He is a good natured pet and he gets on well with adults, children and pets in the home. He can adapt well to life in the city or in the countryside so long as he is with his family members.

He isn’t a couch potato dog though, and wherever he lives, he will need a good amount of exercising. Treat him with the love and respect he craves, and you’ll have a wonderful canine 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

glen of imaal terrier puppies - health problemsThe Glen of Imaal Terrier is a feisty, healthy breed, particularly when he gets the best food there is, then he is not likely to get ill easily.

However, just like other dogs, he can be prone to certain health conditions such as hip dysplasia. When a dog is diagnosed with hip dysplasia, the socket part of the joint is poorly developed, so that is causes abnormal friction.

Inflammation and pain can be the result and your dog can become lame. Unfortunately, rapid weight gain with puppies can put more stress on the hips, and diets without the right balance of vitamins and minerals can be bad for good bone development.

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

glen of imaal terrier dogs - caringCaring for a Glen of Imaal isn’t going to be a huge job. This is what makes him such a wonderful pet as he is a straightforward pet, requiring little more than a brush to avoid the hair matting.

Check his ears, teeth and nails from time to time to ensure he is always in tip top condition.

Diet:

If you intend making use of the convenience of commercially manufactured dog foods, the top quality one will provide you with balanced nutrition for your Glen and you can mix in some cooked brown rice, vegetables and chicken from time to time.

The Glen of Imaal Terrier is a small-breed dog and, he should be offered dog food that has been specially formulated for small, energetic dog breeds. You can also add in a little bit of raw meat into his kibble as a treat as this is important for keeping him free of skin allergies.

Make sure he always has a bowl of fresh, cool drinking 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.
