Dogo Argentino Growth Guide

Breed Overview

The Dogo Argentino, also known as the Argentine Mastiff, was developed in Argentina in the 1920s by Dr Antonio Nores Martínez. Bred primarily for big-game hunting, the Dogo is known for its strength, courage, and loyalty. This breed is confident and protective, making it an excellent guardian and a devoted family companion when properly socialized.

As a large to giant breed, the Dogo Argentino requires close growth monitoring to prevent orthopedic problems. Rapid weight gain or uneven skeletal development can lead to joint issues, including hip dysplasia and osteochondrosis. Proper tracking ensures a healthy transition from puppyhood to adulthood.

How Much Bigger Will My Dogo Argentino Puppy Get?

Most Dogo Argentino puppies reach approximately 50% of their adult weight by 4 months. They experience fast growth between 2 to 6 months, with the most significant weight gains occurring early. While many will reach their adult height by around 12 months, they often continue filling out in muscle and chest depth until 18–24 months.

Rule of Thumb:
To estimate adult weight, double their weight at 16 weeks.

As a large breed, some Dogos—especially males—may continue to mature physically well into their second year.

Dogo Argentino Growth Tips

Nutrition

Feed a large-breed puppy formula with controlled calcium and phosphorus levels to support joint development and prevent rapid skeletal growth. Puppies should eat 3–4 meals per day until 6 months of age, then transition to 2 meals per day.

Avoid overfeeding, which can accelerate growth and increase the risk of orthopedic conditions. Treats should be limited and not exceed 10% of daily caloric intake.

Exercise

Dogos need regular exercise but should avoid excessive jumping or running on hard surfaces during their growth phase. Stick to controlled play, leash walks, and mental stimulation. Overexertion can lead to joint injuries in developing puppies.

Health Watch

Common growth-related and hereditary health concerns include:

• Hip and elbow dysplasia
• Deafness (congenital, especially in white-coated breeds)
• Bloat (gastric torsion)

Regular veterinary check-ups, joint assessments, and a balanced diet are essential to ensure your Dogo Argentino reaches adulthood healthy and strong.
