Pyrenean Mastiff vs Leonberger - Breed Comparison

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 Pyrenean Mastiff originates from Spain, descending from ancient livestock guardian-type dogs.

They have always been used as guardians, looking out for livestock and warding off predators.

When you do research you find that there is little information on the exact origins of the dog. It was only in recent years that the dog was taken out of its native region and sent to the USA, but it isn’t recognized by the AKC.

The dog was however recognized by the FCI in 1982.

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.

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.

This is a fairly healthy dog breed, particularly when you consider what a big dog he is. There are always some health concerns to watch for so that you can take steps to get your pet well again.

Dental Disease:

There is tartar build-up on the teeth and this can lead to infection of the gums and roots of the teeth. Rotting teeth can cause pain, but more worrisome they can cause damage to the heart and kidneys as well as the dog's joints. The vet or professional pet groomers can keep your pet’s teeth clean. They can advise you on how to take care of your large pet’s teeth.

Bacterial and Viral Infections:

Diseases such as rabies and parvo can be prevented by means of vaccine.

Obesity:

You can’t afford for a big dog like this to become obese. It’s a serious disease and can put pressure on your dog’s joints and also cause back pain and digestive disorders.

Parasites:

Your dog can be infected with all kinds of worms and bugs such as ticks d and fleas as well as mites. Some of these parasites can be transmitted to you. Your vet can talk about preventive medication.

Bloat:

Gastric Dilatation and Volvulus, commonly referred to as bloat often occurs in dogs with deep chests.

The stomach twists and fills with gas,and blood to the stomach is cut off. Left unattended to, your dog can die, sometimes within half an hour. His stomach is hard and swollen, requiring immediate veterinary attention.

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.

Spay or Neuter:

Have your pet spayed or neutered if you don’t want puppies. Spaying or neutering also decreases the likelihood of certain types of cancers.

Diet:

Nothing but a top quality diet is good enough for your pet. Commercially manufactured dog foods are a convenient means to feed your pet, and there are some excellent brands.

Look out for the ones for extra large dogs and avoid the ones with low quality ingredients. The dry kibble you give your big pet can be made more tasty when you add some homemade food to it about twice a week.

Dogs thrive on simplicity, so boiled chicken, sweet potatoes, brown rice or pasta, carrots and spinach will be wonderful for him when you chop the food up and add it into the dry kibble. Its such a tasty, wholesome treat for your pet.

Some raw meat added in occasionally will contribute to your pet’s heath. Make sure he is never without a constant supply of fresh, cool water.

Grooming:

Brush his coat at least twice a week. Check inside his ears for redness which could indicate an ear infection.

He’s an intelligent pet with lots of energy, so you will need to keep his mind and body active by ensuring he enjoys walks every day. He isn’t a dog that requires running with you on your jogs or cycles.
