Bullmastiffs should be relatively easy to train if training is started at a young age and continued consistently. An important theme arising in literature around Bullmastiff training is the need for the owner (or borrower) to be respected and known as the dog’s leader. Given the Bullmastiff’s size and predisposition for guarding, if left untrained, the breed can become unruly, difficult and could knock people over. That said, Bullmastiffs react very well to having a purpose and knowing who’s boss. Obedience classes are a very good way to ensure Bullmastiff puppies are socialised and trained to understand basic commands. Training should also take place at home to ensure they know their place in the family pecking order. Treats and pawsitive reinforcement should help ensure Bullmastiffs are engaged and ready to please.
