The Brazilian Dogo is an active and balanced, yet alert, fearless, and watchful dog with a strong guarding instinct. Towards its family, it is obedient, gentle, and affectionate. However, it is serious towards strangers and will be ready to attack if provoked. It should not demonstrate aggressive behaviour without a clear reason - such as purposeful provocation - not even with other dogs. Instead of the more common working trial, a specific character trial is demanded for the breed to reach championship in Brazilian dog shows.
