Dogo Argentino – Owner’s Guide to the Giant Argentinian Mastiff

Dogo Argentino

The powerful Dogo Argentino is sometimes referred to as the Argentinian Mastiff. This impressive dog is fearless yet sensitive and has an almost feline grace. While an energetic outdoors dog, the Dogo Argentino is a calm and happy indoor dog.

Essentially a white Mastiff, the muscular Dogo Argentino was bred for its robust strength and big-game hunting abilities. Interestingly, while this large dog is an aggressive hunter, he actually has a pretty happy disposition, especially with his human family. Fiercely loyal, the Dogo Argentino requires strict boundaries and an experienced owner capable of handling this large breed.

Your dog’s yard must have a strong and tall fence because the Dogo Argentino’s natural instinct is to wander off and chase small animals. It’s also essential that your pet be socialized with other pets and humans to curb their natural caution around other animals and strangers.

Don’t leave your dog alone for long periods because this breed can quickly become bored and indulge in destructive behavior. These dogs need to stay active. When placed in a loving home and with rigid training, your Dogo Argentino will make a fantastic, courageous watchdog and a loving and loyal family member.

History of the Argentinian Mastiff Dog Breed & Antonio Nores Martinez

Argentinian Mastiff

This large breed has a dogfighting ancestry, so that aggression can be an issue. Socializing is key to developing the discriminating, stable temperament this dog is now known for at a very young age. As a descendant of the Fighting Dog of Córdoba (now extinct), this large, fierce breed of dogs were kept for fighting.

In the 1920s, an Argentinian breeder named Antonio Nores Martinez wanted to breed a hunting dog capable of being a loyal companion while also handling his homeland’s terrain. He aimed to replace the dog’s natural fighting instinct with the need to hunt and reduce the dog’s desire to fight to work within a pack through breeding. After several breeding experiments, Martinez achieved what he set out to do. The result was the Dogo Argentino breed.

While this muscular dog now has a strong prey drive, perfect for hunting in Argentina’s rugged terrain, it’s also become a trusted companion and a loyal family guardian. Unfortunately, due to its powerful strength and fearlessness, the Dogo Argentino is often used in dogfighting rings.

Size and Weight

Male Dogo Argentinos are typically taller than females by about an inch and grow to a height of approximately 24 to 27 inches at the shoulder. These dogs usually weigh anywhere between 80 and 100 lbs.

Because Dogo Argentinos have large, broadheads, they’re often confused with the American Pit Bull Terrier and the American Bulldog. With a typically longer body than it is tall, these sizes are referred to as “breed standard’; however, Dogo Argentina’s can be either bigger or smaller.

Personality And Temperament

The Dogo Argentino is an excellent watchdog. They’re a highly territorial, loyal breed and will fiercely defend their human family. The downside is that their strong prey drive does not make them good companion pets for other animals like smaller dogs or cats, but it does make them great hunters – their sheer strength and ferocity make them capable of taking down wild boars.

The Dogo Argentino is an independent dog, so they require an experienced owner or trainer to take on their training needs, especially socialization. These dogs are not exactly renowned for welcoming strangers or other dogs! Training should begin while they are just a small puppy.

This breed requires plenty of mental stimulation and exercise. Unless you live a physical lifestyle and are prepared to stimulate your dog mentally and physically, this dog is not for you. Don’t even consider this breed if you live in an apartment.

Potential Health Issues

There are a few health problems that the Dogo Argentino can be predisposed to, with the main one being deafness. It’s believed that approximately 10% of Dogos are deaf in one or both ears. This affliction is known as Pigment-Related Deafness because of the dog’s white coat. This affliction is also found in other breeds with white coats, including Boxers, Dalmatians, and Bull Terriers.

Other health issues that may affect the Dogo Argentino include glaucoma, hypothyroidism, and laryngeal paralysis. Hip dysplasia, which is quite common among large breeds, can also be an issue.

Physical and Mental Care

Your Dogo Argentino must receive plenty of mental stimulation and lots of exercise because this breed quickly becomes anxious, bored, and destructive when their needs are not being met.

Like any other dog breed, this breed requires regular grooming, vet checkups, and teeth to be kept clean. Their nails should be trimmed monthly, and their ears should be checked weekly. Please consult your veterinarian about caring for your Dogo Argentino at home and follow their instructions.

Feeding Your Dogo Argentino

Feeding Your Dogo Argentino

Besides lots of fresh, clean water, your Dogo Argentino will need a diet specifically formulated for large-breed dogs. Because this is a breed with high energy levels, this will need to be taken into account. Their feeding requirements will change from puppyhood as they grow into adulthood. Again, speak to your veterinarian about an appropriate feeding plan for your dog. You may also choose to seek guidance from a professional nutritionist if you have any concerns about nutrition.

Grooming and Coat Color for the Dogo Argentino

Your Dogo Argentino will have a short, all-white coat, and he may have a black spot on his head. The short coat should mean easy maintenance; however, your dog’s sheer size could make the grooming process quite long. Your dog will require weekly brushing and, unless he gets filthy, he should have a bath every three months. These dogs do shed quite a bit but, because they have a short coat length, their shedding is not as noticeable as it would be with a long-haired dog. A good lint roller should take care of this problem.

Children And Other Pets

Providing your Dogo Argentino has been properly introduced to your family and become accustomed to their presence, you’ll find that this huge dog will become a very loyal and loving family member.

However, you should be aware that your Dogo will not naturally like strangers, so beware of children visiting your home. No children, even your own children, should be left unsupervised with dogs, and it’s vitally important that your dog is trained right from a small puppy on how to interact with other animals. You must begin socializing your Dogo Argentino early and teach him to accept and interact with humans and animals. You can’t start training your Dogo too early.
