Improper socialization can cause these dogs to exhibit wariness towards strangers, as they were originally designed for personal protection.
But their remarkable brilliance lurks beneath their guarded nature.
Because of their high level of training requirements, Dobermans are best suited for more experienced households.
Bullmastiffs are full of love and devotion to their family and are as sturdy as an ox.
Because they descended from estate guardians, they naturally have a protective nature,
but puppies that aren't socialized to sharing space might be aggressive.
If you can bring out their softer side, they will continue to watch with affection rather than hostility.
