Dogo Guatemalteco vs American Mastiff - Breed Comparison

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.

Known as the Guatemalteco Bull Terrier or Guatemalan Molosser, the Dogo Guatemalteco is also known as the Bull Terrier Guatemalteco, Guatemalan Bull Terrier, and Guatemalan Molosser.

This big Molosser-type dog originates in Guatemala. In the 20th century, it was known as the Bullterrier Guatemalteco, but at the end of the century, it was changed to Dogo Guatemalteco.

Today, while the dog is kept as a companion dog, most are working guard dogs. The Dogo Guatemalteco isn’t recognized by any major international kennel clubs. However, the Kennel Club of Guatemala has given full recognition to this dog and it was in 1981 that the Guatemalan government named the dog as their national dog breed.

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 Guatemalteco is a medium to large dog standing at 54 – 60cm and weighing between 40-45kg. He has a short, smooth coat and is essentially white with some black markings on the head.

This breed was created from a crossing between a bull terrier, boxer and dalmatian. Some of the dogs are thickly built, while others are more leaner and athletic looking.

The ears of the dog vary quite a bit because while sometimes the ears fold down closely to the head, others are semi-pricked. There are some dog owners who have their dogs ears cropped into fully erect triangular shapes. The eye are small and usually dark brown.

Temperament:

The Dogo Guatemalteco is a fearless, evenly tempered dog. He was bred as a guard dog and he wants to protect his human family, forming a deep bond with them. It makes them difficult to re-home because of this.

It is imperative to have this dog trained and socialized because it might believe its the leader of the pack in your home. He is quite capable of getting along well with children and pets in the home. Because of his dominant nature, he isn’t suited as a pet for the first-time dog owner. He also doesn’t warm easily to strangers.

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 Dogo Guatemalteco is an intelligent dog breed, and because he is strong-willed and stubborn he might give you a hard time during training. It is possible though and it is important as the training will turn him into an obedient, relaxed dog, able to get on with all his family members, including pets.

He is an energetic dog and will require walks and other forms of exercise each day.

This is certainly not the kind of dog that you buy to protect your property and provide little else for him except food and water. Frustration on the dog’s part can lead to destructive behavior and aggression.

Treat him well and he can make an excellent family companion.

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.

This dog can be susceptible to skin allergies. The skin is sensitive and prone to rashes.

Another health concern with this dog because of his white coat, is congenital deafness. The deafness could be in one- or both ears.

The dog could also experience lameness, of which the most common problem is hip dysplasia. Because skeletal problems occur in this breed, it is advisable for owners to have their pet tested by the Orthopedic Foundation for Animals.

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.

The coat of the dog is short and harsh and it sheds throughout the year. While he is still looked upon as a low maintenance dog, regular brushing will be required twice a week.

Because he is a dog breed that is susceptible to skin allergies, bathing isn't necessary as it removes the dog’s natural oils.

Other areas of grooming for this dog are brushing his teeth twice a week, trimming his nails and checking his ears.

Diet:

Always choose a high quality dog food for your Dogo Guatemalteco and look at the feeding recommendations on the packaging.

When you feed your pet kibble, you can also mix in some cooked brown rice, vegetable and chicken for variety and contentment.

Raw meat is also advised from time to time. Don’t just go on and on through the years feeding your dog the same amount of food, as there are factors to take into account when deciding on food quantity. The age of your dog, it’s stage of life and its activity levels will mean regulating your pet’s food to match his needs.
