Great Pyrenees vs American Mastiff - Breed Comparison

The Great Pyrenees could be from Spain or France because the dog hails from the Pyrenees Mountains, which spans both France and Spain.

The dog was used to defend flocks from predators but its lineage goes a long way back, thousands of years in fact. It is thought that they only arrived in Europe about 5,000 years ago. The dog was adopted into the court of Louis the XIV as a royal dog.

During the mid 1600s, the dog's numbers dwindled but the French developed kennel clubs where the dog could be bred and its numbers restored. It was in 1933 that the Great Pyrenees received American Kennel Club recognition.

The history of the American Mastiff is entirely tied to the old European Mastiffs but in particular the English Mastiff. The developers of the American Mastiff crossed the English Mastiff with the Anatolian Mastiff at the Ohio kennel, Flying W Farms. The founder of this breed is Fredricka Wagner. Because of this the English Mastiff and the American Mastiff look very much alike. The difference between the two is that the American Mastiff was bred to have less health concerns than the English Mastiff and without the drooling. In 2000 the CKC acknowledged that the American Mastiff and the English Mastiff were separate breeds.

This is a beautiful dog, noticeable by the essentially white coat and his overall size, standing at 70 to 82cm and weighing between 40 to 54 kg.

The double coat is medium to long, coarse and straight or wavy and and it can be solid white, cream or white with patches of light tan or grey.

The nose is black, the eyes brown, the ears of medium length and floppy and the tail long and plumed.

Temperament:

The Great Pyrenees is an intelligent, strong willed dog with a mind of his own so he will be able to be trained and socialized successfully.

His huge size will require that he be trained because when he is indoors he can knock things over and he must be able to respond to you telling him to lie down.

As a large dog, he isn’t suited for tiny homes, as he requires lots of space even though he doesn’t require a lot of exercise. Not only that, he takes his watchdog duties seriously and he is inclined to bark a lot, and in a small place, you’ll be getting constant complaints from the neighbors.

When trained and socialized, your big dog is social, active and loving. He gets on well with children, the elderly and with pets in the home. He isn’t that overly active and will happily make himself at home on your couch and bed.

This crossing of the English Mastiff and the Anatolian Mastiff resulted in a Mastiff with a much drier, less drooling mouth than the other Mastiffs. This is a giant, massive dog – powerful and muscular. With a wide head that is rectangular rather than square. Their eyes are dark amber, and their ears are high on their head and rounded. With a medium size muzzle, black mask and heavy head, the American Mastiff is a handsome dog.

Their chest is broad, deep with ribs that extended backward. He has strong legs that are parallel and wide set. He also has a long tail. Puppies of the American Mastiff are born almost black and as they grow their coat color lightens. In addition, it is important that they have a wrinkled forehead as well and a scissors bite is preferred.

The Great Pyrenees is such a calm, independent, serious, well-mannered dog who loves to be around his human family and to please them. He is gentle and knows how to behave well around children, the elderly as well as with any pets in the home.

He makes a wonderful companion and although he loves indoor life as much as outdoor life, he is much happier settling into life in the country or the suburbs as opposed to life in the city and a tiny property.

Give your big white coated pet all the love he thrives on, and you'll enjoy a wonderful relationship with this large, amicable dog.

A love of children and devotion to his pack (family) is bred into the American Mastiff. He is non-aggressive unless you threaten his family or his children. Then he becomes courageous, protective and defensive. This is a gentle giant most of the time, however due to size and the need for strong leadership, the American Mastiff should be socialized and trained early. If they are socialized and trained they will be calm, gentle dogs. They will remain protective and alert, but they will be friendly with strangers. They love to please their people and being highly intelligent they learn fast.

Your Great Pyrenees is a big dog with an average lifespan of 10 to 12 years. His large size means you will need to look out for typical 'big dog' ailments such as hip dysplasia.

This problem can cause your pet to be in pain and he can also become lame, battling to walk and play and battling to get up after lying down.

Also, look out for bone cancer with your pet and as mentioned previously, bloat, which is a life threatening disease where the stomach of the dog swells up.

American Mastiffs seem to have fewer health issues than other larger giant breed dogs. However, they can experience allergies as many large, wrinkled dogs do. They also might have a tendency toward eye issues, hip dysplasia, cancer and heart disease. Bloat might be the most life-threatening issue many American Mastiffs experience.

Exercise:

Your Great Pyrenees isn't going to be a dog leaping around you demanding a game or walk like what you get from some energetic dogs. He certainly doesn't require strenuous exercise but will require a nice, brisk walk every day. Give him some ball or rope games too. He's territorial and likes large grounds to walk around and guard and this constant guarding is a good form of exercise too.

Grooming:

With two layers, the coat of the Great Pyrenees will need to be brushed twice a week to prevent burrs attaching to the fur and to prevent it from matting, It also gets rid of loose hair during shedding.

He tends to drool so it's handy keeping a damp cloth close by just to give his face area a wipe down. Your dog's ears will need to be cleaned with special ear-cleaning lotion and his nails will also need to be trimmed.

Socialization and Training:

Socialize your Great Pyrenees with other dogs and people from a young age. Without proper socialization, this breed can become territorial and possessive of his family, which could lead to aggression. He bonds with his family but tends to be wary of strangers.

Diet:

It is far better to feed your Great Pyrenees smaller meals throughout the day as opposed to 2 large meals a day. A large dog like him can develop bloat from gulping down a large amount of food too quickly.

If you feed your Great Pyrenees commercially manufactured food, make sure it is high in omega 3 and 6 to keep his thick white coat luxurious.

Your dog will need a dog food targeted at a large breed. Remember to include some raw meat as well as cooked chicken, vegetables and brown rice into his kibble and always ensure fresh, cool water is available.

Giant breeds like the American Mastiff are known for growing rapidly as a puppy and therefore proper feeding and nutrition is essential. The slower your American Mastiff grows, the better. Make sure your puppies get enough phosphorous and calcium in their high calorie diet. Free feeding is not recommended. Feed puppies up to 4 small meals per day and feed adults twice a day.

Health issues

As previously mentioned this breed is a fairly healthy one, There, are however, certain evaluations you should do with your American Mastiff puppy to be sure she is in good health. These tests would include an elbow and hip evaluation to check for dysplasia. He should have an ophthalmologist and cardiologist examine him as well. Most American Mastiffs will not have any problems, but these evaluations will help to prepare you if they do. The wrinkles in your dogs; face, around the eyes and muzzle must be kept clean as they can become infected if you don’t.

Exercise and games

Unlike the way he looks, the American Mastiff is not a couch potato, but neither are they a high energy, exercise machine. They do well living in apartments or homes, with or without a fenced in yard. They need a long walk every day. They need mental stimulation through exercise and games. Make sure they learn to love to play so that they don’t become lazy as they age.
