Molossus vs Leonberger - Breed Comparison | Petzlover

Hailing from Germany, and more specifically the city of Leonberg, the Leonberger is a giant dog breed.

A resident of Leonberg, Germany, was looking to develop a dog that resembled a lion and in 1846 it was announced that such a dog had been developed by crossing a Newfoundland, Saint Bernard and Pyrenean Mountain dog.

It was after 2010, when the Leonberger Club of America joined the American Kennel Club, that the strict breeding rules were no longer mandatory for all Leonbergers.

The Molossus has always been a popular dog and they have been around since ancient times. Mastiff type dogs are termed as Molossus.

Of course, when looking at the origin of the dog, there are many unsubstantiated claims about it. It has always been believed that the Molossus was a Mastiff-type dog, ferocious in battle. The Romans were dog breeders and recognized that the Molossus was a talented dog – good at guarding and herding.

Over the centuries the dog has changed but it is believed it was a Mastiff-type dog with a number of other breeds included in its origins such as the Rottweiler, Pug, Bulldog, Great Dane, Alano Espanol and Saint Bernard.

The Molossus isn’t a dog breed itself but rather a category that other dogs belong to. Today there are Molosser clubs and Molosser shows around the world.

As a giant breed, the Leonberger stands at between 65cm and 80cm in height. He weighs a hefty 40 – 77kg both males and females.

These dogs are described as being dimorphic. It means that there is quite a difference in the looks of the males and females, with the male dogs being heftier and larger than the females.

The head of the dog is large, he has almond-shaped, dark brown eyes and the ears are medium sized and floppy. The tail is long and he has webbed feet which makes him a good swimmer too.

The thick, double coat can be straight or wavy and comes in different colors such as reddish-brown, tan, sandy or yellowish and the hairs can be tipped with black. He sheds quite a bit so will need regular brushing.

The Leonberger can have between 6 – 14 puppies and these puppies are like big, fat, cuddly, fluffy teddy bears. Don’t be tempted to just buy one because of his wonderful looks because they turn out to be huge dogs that eat a lot and the coat can take quite a bit of effort to keep groomed.

Temperament:

Fondly referred to as the Leo, this giant beautiful dog is social and in spite of his size, he should never be left alone in the backyard for long periods of time. He needs to come indoors from time to time to enjoy some interaction with his human family.

He is a family dog, and with training and socialization, he becomes a well-rounded, confident, obedient pet, quiet and content and sensitive to his owner’s moods.

Even though he becomes a great family pet, you need to think twice before you decide to own one of these large dogs as he can be costly to feed.

This Ancient dog breed from Greece has different descriptions of what it really looked like. It seems to have always been large to medium sized dog standing in the region of 50 to 76cm in height and weighing anything from 25 to 55kg.

The coat is mostly short and smooth and can be in a host of different colors. They are large boned dogs, solidly built with medium sized floppy ears, a short, thick neck, short, broad muzzle and a long tail which was later docked.

Molossers typically have heavy bones, pendant ears, and a relatively short and well-muscled neck, with a short, broad muzzle. These Molossers have always been used for a variety of jobs where strength, perseverance, speed and braveness are required. They have been used as rescue- and guard dogs, protecting livestock from predators.

Temperament:

The Molossus dogs all have the same kind of characteristics which have been bred into them. From their working days, they are known for their tremendous courage, taking on wild animals to protect their livestock.

They are territorial, wanting to protect their human family and home from intruders.They have also been bred to be loyal, loving family pets, and being highly affectionate, they want to be involved in the activities of the family.

This breed is gentle and loving, social and active and gets on well with other pets in the home as well as with children. They’re intelligent dogs and will need to be trained and socialized to ensure they are obedient and amicable with visitors to the home.

Don’t be deceived by the looks of the big Leonberger because he isn’t aggressive, but quiet and calm. Large he may be, but he isn’t sluggish either and he will certainly require exercise such as a long, fairly lively walk every day.

They’re intelligent dogs too and respond well to socialization and training. He is a social dog and wants to enjoy plenty of interaction with his human family members.

These dogs are often used as rescue- and therapy dogs as they are so loving and sensitive. Give him lots of love and good care and you’re going to have the most wonderful pet that lives up to the saying – dogs are man’s best friend.

The Molossus, contrary to what many people think, isn’t a vicious dog, but rather a good natured dog that makes a wonderful family pet.

These dogs are known also for being hard working dogs with characteristics of bravery. They are dogs who may look fairly tough, but they are actually gentle, calm and sensitive. It’s a bad upbringing from the owners that gives any dog bad characteristics.

Train your Molossus, have him socialized and be a responsible and loving dog owner, and these dogs promise to make you a splendid family pet.

Leonbergers are strong, generally healthy dogs. It is said that very large dogs like this don’t live as long as smaller dogs and they also face more health issues. Orthopedic issues such as hip dysplasia are more common with large breeds.

Hip Dysplasia:

An orthopedic problem like this is a misalignment of a joint. This large dog also tends to develop elbow dysplasia too. Fortunately today, hip- and elbow dysplasia is controlled because of efforts of breeders to have their Leonbergers screened.

Nonetheless it is important to know about this ailment. The word ‘Dysplasia’ is referring to an abnormality of development. With both hip- and elbow dysplasia, there is abnormal development of the joints, and osteoarthritis can build up, causing lameness for your giant canine.

Cancer:

Cancer is sadly a leading cause of death in dogs over the age of 10 years. Lymphoma is a blood-related cancer – a tumor of the lymph nodes. Dogs can develop different forms of lymphoma. The warning signs are a lump or a wound that won’t heal, swelling in the bone and abnormal bleeding.

Luckily cancer is very treatable in dogs, but you need to get your dog to the vet as soon as possible.

These large dogs are particularly prone to health issues such as hip dysplasia, a genetic condition. A poor diet as well as environmental factors can contribute towards the disease too as well as rapid weight gain and obesity.

This disease develops because the dog’s hip joints haven’t developed properly. The hips then partially dislocate, and the dog has pain and battles to get around. If your dog shows signs of hip dysplasia, he will need to get to the vet to do a physical exam and come up with a treatment- and management program.

That long coat of the Leonberger is going to require some brushing at least twice a week. He is also a moderate shedder and you want to get rid of all that loose hair and to keep him looking well groomed.

Diet:

A proper, nutritious diet is an essential part of having healthy, happy dogs and if you’re unsure about how to feed your giant pet, speak to your veterinarian.

The best diet for dogs is always very debatable, but essentially it needs to be kept simple. Try and invest in the very best commercially manufactured dog food for large breeds. Every dog wants a tasty home-made morsel from time to time. Add in cooked chicken, brown rice as well as cooked or raw vegetables. Raw meat can also be added in from time to time.

You want to avoid feeding the Leonberger puppy a high protein diet as this encourages rapid growth and you want to avoid that.

Exercise:

These dogs were bred to be working dogs and they have always spent their time outdoors performing a guarding or rescue role. Today they require a lot of exercise – walks and ball games – as they are dogs with a lot of energy.

Diet:

Essentially a large breed, the Molossus will need a commercially manufactured food of high quality if you opt to make use of the convenience of these foods.

Make sure to choose one manufactured for large breeds and which is free of a host of bad ingredients such as corn, soy, wheat, dairy, artificial colors, sweeteners and preservatives.

You want dog food which is high in protein and fat. Try and include some home-cooked food such as boiled chicken, brown rice, pasta and vegetables. An ingredient to look out for in your dog’s food is omega-3 fatty acid to help keep the skin and coat shiny and healthy. Puppies particularly benefit from DHA, or Docosahexaenoic acid, a form of omega-3 fatty acid that is good for brain development.

Grooming:

Brushing the dog’s coat twice a week will be necessary to remove loose hairs, especially during the shedding period. When you brush him, check for ticks and fleas and speak to your vet about flea treatment if necessary. Ears and eyes should be checked and cleaned regularly.
