Leonberger vs Bullmastiff - Breed Comparison | Petzlover

The Old English Mastiff as well as the Bulldog are the breeds behind the Bull Mastiff. The Bullmastiff was originally developed in England around the 1860’s. Gamekeepers in England wanted a large, brave, robust dog which could help with keeping poachers away from their large estates which kept game.

As these large estates dwindled, so did the need for the services of the Bullmastiff and later they were simply bred to be family companions. As more Old English Mastiffs were bred, the dog became lighter, so that light tan or fawn became the preferred color.

The breed was officially recognized by the English Kennel Club in 1924, and the American Kennel Club in 1933.

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.

Bullmastiffs are large, brachycephalic dogs, and heights are between 61 and 68cm and the dog weight anything between 41 – 59kg. While it isn’t particularly tall, the dog is thickly set with a deep chest and strong, muscular legs. The Bull Mastiff has a powerful build and plenty of strength with an imposing look on his face. He is a powerful, active breed with a short coat which is also weather resistant and can be any shade of fawn, red or brindle.

The dog has a black muzzle and the skull is large and square. The ears are set high and are short and floppy. The tail was once docked, giving the dog an even more distinctive, powerful appearance, but these days, due to regulations, the tail is left long.

Temperament

The Bullmastiff is a loyal, devoted, fearless, protective dog. When he belongs to a human family, he becomes a companion but a fierce protector too, being a territorial dog. They love being with their family and can be good with children too, and even other pets, but proper training and socialization will be important. They aren’t aggressive around strangers, though he does make a wonderful guard dog.

He is intelligent and stubborn and if you don’t want him becoming destructive, even though he is a low-energy dog, you will need to exercise him and walk him every day.

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.

Contrary to his formidable looks, the Bullmastiff is a gentle, affectionate pet when he has been properly socialized. He is a great pet for families and will guard them with his life. He is loyal and devoted but can be somewhat aloof, particularly with strangers.

He isn’t a highly energetic dog and he is more or less low maintenance and easy-going. Feed him correctly, give him a nice, warm sleeping spot to call his own and give him attention like he deserves as a family member. The Bullmastiff will reward you by being a solid and devoted companion.

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 Bullmastiff is a generally healthy breed, but even so, the breed is known for having to contend with certain health issues. He doesn’t have a particularly long life span either and can live to be about 10, ll or 12 years of age. Some of the more common illnesses to look out for include -

Hip Dysplasia:

This is a condition where the thighbone doesn’t fit properly into the hip joint. The troublesome part is that it can lead to arthritis, pain and lameness for your pet.

Bloat:

This is a worrisome, life-threatening condition for a dog, particularly for large, deep-chested dogs such as your Bullmastiff. Instead of feeding your Mastiff one large meal, it is recommended to feed him 2 smaller meals. Bloat occurs when the stomach is distended with gas or air and twists, restricting the normal return of blood to the heart.

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.

Grooming for Health and Happiness

The Bullmastiff has a short dense coat which is looked upon as low-maintenance. He will require a brushing twice a week, being a light to average shedder. He is a dog that tends to drool quite a bit so you may need to wipe away slobber from time to time. Because his face has wrinkles, check the creases to ensure they remain free of dirt and food particles to ward off infection.

Check his ears at the same time, brush his teeth at least twice a week with special dog-toothpaste and brush and keep the nails trimmed.

Diet:

Your large Bullmastiff will require high-quality commercial dog food but he will also need some home-made food in between such as rice, vegetables and meat. He is a large dog and will have to get an intake of raw meat too. Dogs denied raw meat can end up with skin problems as well as other health issues.It is better to feel your Bullmastiff smaller meals than to give him one large meal which he scoffs down quickly. Smaller meals will help prevent the most dangerous illness known as Bloat.

Ensure he has a steady supply of fresh, cool water.

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.
