Newfies are intelligent and as such in the right hands, they are easy to train. With this said, their training and education has to start as early as possible and it's crucial that puppies be well socialised from a young age for them to mature into well-rounded dogs. These large dogs do not respond well to any sort of harsh training or correction, they do answer well to positive reinforcement training methods that are always fair and given by people in a calm way.
Newfoundlands also need to be given lots of mental stimulation for them to be truly happy, well-rounded dogs because if left to their own devices such a large dog will start to find their own ways of entertaining themselves which includes being destructive around the home.
