Spanish Mastiff vs Leonberger - Breed Comparison | MyDogBreeds

The Spanish Mastiff is a giant breed that comes from Spain. He has always been a guardian dog.

He is an ancient dog breed, in fact dating back to medieval times. He has always been a guardian of livestock, protecting them from attacks from wolves and other predators.

The first breed standard of this pure breed dog was made by the FCI in 1946. A breeding program was also formed for this dog In 1981.

The dog was recognized by the United Kennel Club in July 2006.

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 Spanish Mastiff weighs between 52 and 100kg and the dog’s height is between 72 and 88cm. He has a thick, heavy coat with rustic colors of fawn, black, grey, reddish and yellow as well as brindle.

He is powerful and muscular with a huge head. The ears are medium length and floppy and the tail is long. If you were looking for a puppy, the American Kennel Club is the only site which has 100% puppies from AKC-Registered litters.

Temperament:

Large, kind, gentle and intelligent, the Spanish Mastiff is well balanced. When you see him you won’t find a dog that is light on his feet and who jumps around excitedly. He is a dignified, intelligent dog, quiet and calm.

Even though he is so calm, it is still a good idea to have him trained and socialized as his very size could be a problem. When you tell him to lie down, you want him to listen to you. This big, gentle giant is devoted to his human family ad takes the role of guardian and protector seriously.

He isn’t suited to life in the city but is better suited to a large property, also because he has a loud bark.

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.

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.

It is good to be wise about some of the common dog problems there are that could plague your Spanish Mastiff. Vets are very familiar with these dog illnesses and they tailor their treatment to suit the needs of your dog.

Remember to get your pet vaccinated against the terrible diseases you get that can kill a dog – rabies, parvo and distemper.

Obesity:

People often think that obesity is something that isn’t dangerous, when in fact it is a serious disease that can cause joint problems, digestive disorders, heart disease, back pain and hip dysplasia.

Dehydration:

Dogs rely on water just like what humans do to keep them healthy and functioning properly.

Water is critically important to every organ and also assists with digestion. Your dog is panting and urinating throughout the day and needs to replace the liquid he loses.

Dehydration in dogs results in loss of electrolytes, such as sodium, chloride, and potassium.This is bad as these minerals have important functions.

A dog that is dehydrated has loss of appetite, loss of skin elasticity, is lethargic, has sunken eyes, wants to vomit, has a dry nose and thick saliva. No dog should ever be left without a constant supply of fresh, cool water day and night.

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.

Diet:

These are giant breed dogs, so you have to be careful with the way you feed them. Large dogs like these are prone to hip dysplasia so you need to choose a food which has ingredients that work to prevent this disease.

You have to be very careful that you don’t overfeed your dog so that the extra weight puts strain on the joints.

This dog will do well with some raw meat added into his diet. Also, include home-made food too. Boiled chicken, brown rice or pasta, sweet potatoes, carrots and spinach chopped up and added to his dry kibble for giant breeds. Added in twice a week can do him the world of good.

Remember to never leave your dog without a constant supply of fresh, cool water.

Grooming:

A good bush of the thick coat twice a week will keep the Spanish Mastiff looking his best.

The nails will also need to be trimmed regularly to avoid overgrowth and to avoid the nails catching onto things. The ears too should be checked regularly to avoid dampness inside the ear which can cause bacteria.

Exercise:

As a fully grown adult, the Spanish Mastiff isn’t a frisky, frolicking dog but he will still require daily exercise. Options for exercise include long walks, hikes, swimming and ball games.

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.
