Siberian Huskies are dogs which were bred to survive and thrive in extreme climates as a working dog and they are therefore highly energetic. They need around 2 hours of walking a day and as much of this time of possible should be spent of the lead. Sufficient exercise and mental stimulation is very important for the breed to avoid serious behavioural problems which can develop if they are not provided with an appropriate means of release for their high energy levels. Huskies that are not exercised sufficiently can also tend to become overweight.
