Dogo Argentinos are large and muscular dogs. Males typically stand between 24 to 27 inches (61 to 68 cm) tall at the shoulder and weigh between 80 to 100 pounds (36 to 45 kg). Females are generally slightly smaller, standing around 23 to 26 inches (58 to 66 cm) tall and weighing between 70 to 90 pounds (32 to 41 kg).

Dogo Argentinos are known for their loyal, protective, and confident nature. They are highly devoted to their families and can be affectionate with children. However, their strong prey drive and protective instincts mean that early socialization and training are crucial to ensure they are well-behaved around other animals and strangers. They can be assertive, requiring an experienced owner who can provide consistent leadership.

The Dogo Argentino has a short, dense, and smooth coat that is predominantly white. Some individuals may have small patches of color (such as brindle or black) on their ears or body. The coat is relatively low-maintenance, requiring minimal grooming, though regular brushing can help manage shedding.

Dogo Argentinos thrive in active households where they receive plenty of exercise and mental stimulation. They do best in homes with space, such as those with yards or rural areas. This breed is not suited for a sedentary lifestyle and enjoys being part of family activities, including outdoor adventures.

Dogo Argentinos require regular physical activity to maintain their health and well-being. Daily walks, runs, and play sessions are essential for their happiness. They excel in activities that engage their hunting instincts, such as tracking or scent work. Additionally, they can participate in dog sports like obedience trials, agility, and protection training, which can provide both physical challenges and mental stimulation.
