Hi there.
ARE THEY EASY TO TRAIN
Has I have a Bullmastiff myself, I would say they are easy to train, BUT he can become easily bord and distracted so we recommend to keep lessons short.The addition of food treats as rewards is also beneficial as they are a food driven breed of dog. We also recommend to always leave training on a good note and keep it fun.
ARE THEY A GOOD GUARD DOG
This is a breed that was bred solely to guard, therefore it is their natural instincts, they are not a herding breed unlike most other large breeds that are for some reason used as guard dogs. Without a doubt even the most aloof of the breed will surprise you. I call the Bullmastiff the natural guardian, as they know the TRUE meaning of danger and act. Occasionally depending on the individual character some can become overly protective of his family.
DO THEY DROOL
They will drool if you happen to be eating in front of them or if it is a hot day or if they have just had a drink, a cloth should always be at hand.
