Bullmastiffs, despite being large, powerful dogs are incredibly easy to train. They’re intelligent, adaptable, and master new skills and commands quickly. But, it’s important to put the time and effort into training then that they need, which means that ideally, you devote at least two hours a day to exercising and training a Bullmastiff in order to ensure that he learns to follow your commands and listen to you.
They also have a tendency to be stubborn, single-minded dogs, so it’s vital to start training them as early as possible, and because they can also be aggressive toward other dogs of the same gender, Bullmastiffs need to be properly socialized from an early age, as large, snarling dogs can be frightening and the way they behave toward, and with other dogs needs to be brought under control as early as possible.
