Training Tips

Begin training while they're still manageable in size. A 120-pound untrained Bullmastiff is nearly impossible to handle.
Socialization is Essential
Natural guardians need extensive early exposure to people and situations to prevent over-protectiveness.
Keep Sessions Short
Low energy and can be stubborn. Multiple short sessions work better than long ones.
