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.
Throughout most of history there have been images created by people of very large, sturdy dogs that they shared their space with. The English Mastiff can trace some part of her ancestry to these same dogs. This breed is thought to have come from the stock of ancient breeds such as the Alpine Mastiff, Pugnaces Britanniae and Alaunt. The Mastiff in general has then become a main descendent of many other breeds of dogs since the 1880’s. The images of these types of dogs goes back to the 5th and 6th century.
There is no genetic evidence linking these dogs to the modern Mastiffs and the English Mastiff, but the resemblance is obvious. There is anecdotal evidence that these Mastiff type dogs were exported from England – the English Mastiff – to Greece to hunt game but were also used as war dogs by the Celts. The Alaunt was probably used the Normans and bred by the Alans. Writings and images throughout these times depicted a dog that looked very much like today’s English Mastiff. Some speculate that the English Mastiff came to the United States of the Mayflower.
There was a decline in the English Mastiff in its homeland in the 1800’s following the Cruelty to Animals Act of 1835 which prohibited owners and trainers from baiting animals. Then in the 19th century, prior to the first World War, systematic breeding programs began with J.W. Thompson. His first English Mastiff was a female named Dorah. Dorah’s ancestors included dogs from Thompson’s Grandfather. Captain John Garnier of the Royal Engineers also had dogs that contributed to the development of the English Mastiff.
During this time some breeders got away from pure type and began to breed for other factors. In the late 1800’s, Edgar Hanbury and Mark Hanbury Beaufoy began restoring the breed to its original soundness. One of their dogs was exported to the US were breeding to soundness continued until the First World War reduced the number of English Mastiffs around the world. By the time the war ended there were no English Mastiffs outside of England.
There was a dog in Canada named Beowulf and direct descendent of imports from Britain, who came to the States after the war and began to re-establish the breed on this continent and registered with the American Kennel Club. Yet as of 1945, the contribution from North
Breeding was stopped again for World War II and started again after the war. Many of these puppies died of distemper. Only one female had pups that were able to grow up into adults. North America sent dogs to England at this time and all of the Mastiffs from that time, could be traced back to Nydia and the 14 North American Mastiffs. Since then the breed has been restored slowly in Europe, North America and everywhere in the world.
The English Mastiff is known by his massive head with a black mask and comes in a wide variety of colors. He is also known as a gentle giant because of his personality and the love he has for his people.
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.
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.
The English Mastiff is a giant dog with a broad head and body. In terms of mass it is the worlds largest dog, just a little bigger that the Saint Bernard. The Great Dane and the Irish Wolfhound are 6 inches taller but do not carry the weight and bulk of the Mastiff. Mostly square in his body and his head with a massive chest and wide set forelegs. The head is square and very large. No matter the color of the coat, the face should have a black mask like the St. Bernard. His eyes and nose are also dark.
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 English Mastiff is very happy to play with children. You willl need to be careful with small children as he does not know his size and is likely to sit on them.
This lovable giant is noble and loyal. He will protect his family and he will be courageous about it.
This is a big dog but he doesnt live outside. You need a big yard and perhaps a big house. He may not adapt to an apartment.
The English Mastiff is smart and certainly trainable. He can be independent and stubborn at times but he has the ability to learn.
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.
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 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.
Being a massive dog can take its toll on the body’s development and that is certainly true of the English Mastiff. A lot of running is not recommended in the early life of the dog – preferable for the first two years. This could damage the joint’s growth plates and cause him a lot of problems in later years. Too much exercise in this massive dog can hurt him but so can, not enough exercise.
Some of the health issues other than this that the English Mastiff is prone to include:
A large dog like the English Mastiff is always prone to pain from arthritic joints. See your vet about pain medication.
A spot under the skin that is swollen and filled with fluid. Can be treated. It is not an infection or contagious.
Can result in lameness and arthritis.
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.
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.
This is an enormous dog that grows quickly. It is important to feed them properly as they grow. If he doesn’t get what he needs as a puppy you will not be able to make it up to him later on.
The English Mastiff puppy needs good nutrition for growing properly.
From 12-16 weeks of age feed him 3-4 cups a day of a high protein, high quality dry food. Break this up into 3-4 meals.
From 4 -6 months of age feed him 8-10 cups a day of a high protein, high quality dry food. Break this up into 2-3 meals.
From 6-18 months of age feed him 8-12 cups a day of a high protein, high quality, dry food. Break this up into 2-3 meals.
The English Mastiff is still growing from a year to 18 months. Starting at 18 months feed him 10-12 cups a day of high protein, high quality dry food. Break this up into 2 meals.
As your Mastiff ages, cut down on the protein and feed a dry food appropriate for his age.
The English Mastiff is a very large dog that should not be allowed to get obese since he is prone to dysplasia. He needs protein throughout puppyhood and until he is about 8-10.
This is a couch potato if you let him be. Make sure he gets at least one long walk per day or he will tend to gain weight. Play with them off leash about an hour every day.
