Care and feeding
The St Bernard needs a balanced canine diet suited to its size and age, with weight control and fresh water always available. Look after its dental hygiene, brushing according to its coat, nails and ears, and keep up with vaccinations and deworming. Regular veterinary check-ups are key to catching any problem early.
Exercise and stimulation
The St Bernard needs daily walks and exercise to match its energy, plus mental stimulation through games, obedience or interactive toys. A dog that moves and «thinks» every day is a more balanced dog: the right exercise prevents boredom, stress and excess weight.
