Giant Schnauzer vs American Mastiff - Breed Comparison

As a working dog breed, the Giant Schnauzer, known also as the Riesenschnauzer, hails from Germany.

It is believed that the first Giant Schnauzers emerged in Bavaria in the 17th century already. It is the largest of the 3 Schnauzer dogs – Miniature, Standard and Giant. There are quite a few breeds which have been used in its development – Bouvier des Flandres, Great Dane and the German Pinscher among other.

The dog was bred to work on farms and also used as a military dog during the World Wars.

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.

With a thick, medium length double coat to protect him from the weather, the Giant Schnauzer’s coat is essentially wiry and hard and in solid black or in a greyish salt and pepper color.

The dogs have always traditionally had their ears and tails docked at the 2nd or 3rd joint to set them apart in looks, but these days both the ears and tail are left.

The tail is always held high. He has dark eyes. Like all Schnauzers, they have that distinct beard and eyebrows. The dog is large and well built and stands at 60 to 70cm in height and weighs anything between 25 and 48kg.

Temperament:

Intelligent, strong willed and energetic, the Giant Schnauzer is actually a quiet dog who doesn’t respond too well to strangers, being reserved around them.

He has a natural guarding and territorial instinct. When he is trained and socialized he makes a wonderful pet, responding well to a firm, consistent owner.

He loves his human family, and as a stable, reliable kind of dog, whether you’ve got children in the home, pets or elderly people, you can rely on your Giant Schnauzer to be a dependable, gentle pet at all the right times, being playful and energetic at other times.

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 Giant Schnauzer has many excellent characteristics which make it such a great pet. He is composed, alert, intelligent, loving and loyal to his human family.

He is also playful, being happiest when roped into everything going on in the family. He has a solid, balanced nature, is robust and hypoallergenic.

He is powerful and needs a good dose of exercise and will love to join you on your cycle- and hiking trips. Good with children and pets in the home, this is a dog breed that will make a splendid, reliable pet.

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.

A healthy Schnauzer can reach 10 – 12 years of age, but even so, they are a dog breed prone to high rates of hip- and elbow dysplasia, hereditary eye disease and thyroid disease.

Blood-clotting diseases and epilepsy are also concerns with Giant Schnauzers as well as bloat. As with all deep-chested breeds, Giant Schnauzers are more at risk with this gastrointestinal syndrome known as bloat and which can be life threatening.

It is your right to ask the breeder about the medical history of your puppy’s parents.

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.

He is a particularly low shedding dog and so brushing him twice a week will suffice. He loves the closeness with his human family during these grooming sessions.

If you don’t know how to groom yourself, the Giant Schnauzers coat will require hand-stripping or clipping. If you want to keep your dog with that typical Schnauzer look, a visit to a professional groomer will be required as they will also tidy the hair around each paw as well.

Now that the ears are no longer cropped, he has fairly short floppy ears and it will be necessary to ensure that dampness, ear wax and dirt don’t build up to cause ear infections.

The teeth must also be brushed 2 or 3 times a week otherwise plaque buildup can cause dental disease as well as lead to other more serious diseases such as kidney- and heart disease.

Diet:

If you’re a new dog owner, it can be hard to know which dog food to buy and which ingredients to look out for. Nutrition is of vital importance, and bad ingredients can make your dog sick and shorten his life.

A mix of the best commercially manufactured kibble mixed with home-made food full of the right balance of vitamins and minerals will be important as well as including some raw meat into the diet.

If in any kind of doubt about how to feed a large, energetic dog breed like this Giant Schnauzer, speak to your vet.

Exercise:

As a big, energetic dog, the Giant Schnauzer needs to live on a property where there is a garden. He will be requiring some hectic exercise every day.

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.
