Giant Maso Mastiff vs American Staffordshire Terrier - Breed Comparison

The Giant Maso Mastiff is a fairly new dog breed so you aren’t going to find much history on him.

The breed was only started in 2001 so as to create a mastiff dog that would have fewer health problems and therefore have the chance to live longer. The Giant Maso came about because of a mix between the Old English Mastiff and the Cane Corso Italiano.

As stated, breeding began in 2001 and the dog has inherited intelligence and protective instincts from both these dogs.

The American Staffordshire Terrier is a part of all the confusion surrounding the group of “pit bulls”. The American Staffordshire Terrier is directly related to the English Bull Terrier and English Terrier. The breed of the English Staffordshire Terrier was bred in the early 19th century in the West Midlands. It was not until later that the breed came from Staffordshire. These English Staffordshire Terriers are also the source of contention by breeders who insist it was the Fox Terrier, White English Terrier, Tan and Black Terrier that are the ancestors of the English Staffordshire Terrier.

These terriers (AKA pit bull terrier) came to the United States in the mid 1800’s. By the late 1890’s they were accepted by the United Kennel Club (UKC)as the American Pit Bull Terrier – a new and distinct breed. There were also some that were accepted into the AKC as the Staffordshire Terrier. In England they were still known as the American Staffordshire Terrier. When the AKC accepted the breed in 1936 they were given a new standard, new purpose and new group – the terrier. In 1969 the American Kennel Club recognized these dogs as American Staffordshire Terriers and refused to recognize the American Pit Bull Terrier. The name was changed to move the breed away from its characterization as a bull fighter and to distinguish it from the smaller English Staffordshire Terrier. All American Staffordshire Terriers are directly related to the American Pit Bull Terriers.

The American Staffordshire Terrier is a strong, powerful dog – stocky, muscular and graceful. At one point in time the American Staffordshire Terrier and the American Pit Bull Terrier were considered to be the same breed. Even today there are those that make that argument, but they have been recognized outside the AKC as separate breeds. The AKC only recognizes the American Staffordshire Terrier and not the APBT. However – even though there have been decades of separation in breeding the American Staffordshire Terrier and the American Pit Bull Terrier are the very same dogs genetically.

The American Staffordshire Terrier has a broad skull, high set ears and pronounced cheek bones. Their ears should not be cropped by AKC standards and their eyes are far apart, round and dark. With a medium sized muzzle and a heavy muscular back, they are as powerful as they look, if not more so. Most have black noses. The AmStaff has a broad, deep chest with wide set forelegs and compact feet. The tail is short and tapered and it should not be docked.

The American Staffordshire Terrier is a loving, gentle dog that wants nothing more than to be with and please his people. Contrary to his reputation as a “killer”, this dog is actually a lover. They are great with children and want to be a part of the family. They even think they are lap dogs, regardless of their size. They are never going to be aggressive toward people and even though they are not one-person dogs, they are loyal, and they are devoted to the family and the “leader of the pack”.

This breed can tell who is their friend and who is not. They are not aggressive, but they will protect their own. They are courageous, confident, attentive, bold and strong-willed. The AmStaff gets along with other dogs most of the time, but they will never back down from a challenge and should never be left unsupervised with another dog. They should not be loose in a neighborhood or at a dog park. No matter how much you trust your American Staffordshire Terrier they can be killers in any fight with another dog.

In addition to this you must socialize and train your AmStaff. You need to be the pack leader and be in control. The AmStaff wants to please you so for a strong leader they will respond positively to positive training. They are intelligent and pick up quickly on what you want them to do. However, they are incredibly strong physically so training them to heel and walk with you obediently is a must. A well trained and exercised American Staffordshire Terrier is a happy dog and a loyal family dog.

There has always been the concern with joint disorders in large breed dogs. Both hip- and elbow dysplasia can occur with your Giant Maso Mastiff, more so if you overfeed him as a puppy and he grows too fast.

With hip dysplasia, the long bone of the leg forms incorrectly. This can lead to pain and lameness with your pet.

Also check out bloat. This is a serious illness when the stomach fills with air and can twist. Gastric Dilatation-Volvolvus, is an emergency situation then which is found more often in large, deep-chested dog breeds.

If you see your dog with a bloated stomach and acting in a strange, lethargic way, get him to the vet immediately as bloat can be life threatening.

For the most part the American Staffordshire Terrier, like most of the “pit bulls” is a hearty, healthy dog. They have a few tendencies that breeders should test for including hip dysplasia, allergies, and heart issues. They can test for Cerebellar ataxia, which has affected the AmStaff with a progressive decline in their ability to control their muscles and coordination.

Grooming:

As an average shedder, the smooth, shorthaired coat is easy to groom, and a good brush twice a week will be adequate.

The Giant Maso Mastiff has floppy ears and therefore these should be checked for ear infections. Wax build up and dirt will need to be checked and cleaned.

His nails will need to be clipped, especially if they don’t wear down on their own and his teeth will need to be cleaned 2 or 3x a week to avoid dental disease.

Diet:

With a large dog breed puppy such as the Giant Maso Mastiff, rapid growth is a risk factor for developing joint and bone conditions. The growth period can last till 12 months and puppies of large breeds should actually have their caloric intake adjusted during this growth period.

It is important to ensure that your puppy grows at a slow, steady rate. If you are feeding dog food from the commercially manufactured range, if you aren’t sure, speak to your vet about large breed dog foods. You want to be sure that this gentle giant of yours receives the best dog food there is, whether commercial branded dog food or your own home-made food. Good nutrition is imperative for the health of your pet.

feed You can feed your American Staffordshire Terrier either commercially purchased food or food you make yourself if the quality is high, nutrition is good, and the amount eaten is determined by the owner. Do not free feed. The AmStaff has the tendency to become obese. Its ok to use treats for training and rewards, as long as its use is controlled.

Health issues

As previously mentioned the American AmStaff Terrier has a tendency toward a few health issues. Hip Dysplasia – this condition causes a lot of pain and disability. It leads to different types of arthritis and degenerative joint disease. Cardiac Issues – Congenital heart disease consists of vessel malformation and lesions.

Allergies

Thyroid Issues

The AmStaff can be susceptible to Autoimmune Thyroiditis. This is a form of hypothyroidism developed by dogs. It is usually seen between 2 and 5 years of age. Continual retesting is recommended.

Cerebellar Ataxia

This is the most dangerous disease possibility that the American Staffordshire Terrier faces. There is a test for this condition which causes the AmStaff to display an inability to control their muscles and a loss of balance, to the point of falling. This is a progressive disease that often leads to euthanasia. The Staffordshire Terrier Club of America suggests that AmStaffs carrying the NCL genes should never be bred.

Exercise and games

The American Staffordshire Terrier is an energetic, and athletic dog that loves to play and needs plenty of exercise. This breed is oriented to people and should never be left alone in the yard all day as a way for her to exercise. She needs you to play with her. If you cannot do this, then you should not own this breed of dog. This breed also loves to play canine sports. They thrive on games like dock diving, agility and obedience competitions. They excel at search and rescue. These are competitive dogs that want nothing more then to please their people.
