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.
Following World War II, the American Bulldog was almost extinct.
Thanks to John D. Johnson from Summerville, Georgia the breed is still with us today. He gathered the best dogs he could find throughout the rural South and bred them back into popularity among his family and other rural families. His father bred the American Bulldog before John did and they have bred them longer than any other in any part of the world. His dogs were regularly used for tracking, hunting, guarding, watchdog and weight pulling. At some point Alan Scott joined Johnson breeding other bulldogs to Johnson's and forming the Standard American Bulldog.
The American Bulldog/ is popular today as a family pet and companion as well as a working dog.
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 American Bulldog is characteristically loyal, brave and reliable. It is a friendly, gentle dog that truly loves children. There is not a hostile bone in his body despite his history and reputation for bull baiting. Though he is protective of its family and affectionate with most, he still needs a human companion who is strong willed and a genuine pack leader. Without this he might become aggressive around other dogs and pets. They are immensely self-confident and they do slobber and drool and will become excited and hard to handle without daily exercise of both their body and their minds.
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.
Though generally healthy, the American Bulldog is prone to a few problems.
This is a serious issue in many breeds of dogs and is especially prevalent with the American Bull Dog. This may seem ironic in such a short legged dog but it is unfortunately very common. It is a genetic disorder that causes the bones in the joint to separate and causes the dog much pain and lameness.
Due to skin folds you need to be care and watch for irritation and infection in the folds. They are also prone to ear infections.
The American Bulldog is prone to overeating and all the health issues that presents. With short legs and a genetic predisposition to arthritis and hip dysplasia, obesity is a real health risk for your bulldog.
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.
Three times a day from 12 weeks to a year for a total of 3 cups per day.
After 6 months cut back to one cup twice a day of high quality dry dog food.
Bulldogs will eat anything at anytime and are prone to obesity. Don't overfeed them.
