When do Fila Brasileiros stop growing?

Fila Brasileiros stop growing by about three years old. They typically reach their full height around 18 months. However, they continue to gain muscle and reach their full weight by about three years of age. 

Switching these dogs to adult food once they’ve reached most of their full height at around 12 months old is advisable. Adult food is less calorically dense and will help ensure they develop at a safe rate, as growing too quickly can cause joint problems.
