How much exercise do they need?

They are a sporting breed and as such need plenty of exercise. They will benefit best from regular periods of high intensity activity once they are fully grown. This includes a quick session of fetching, romping with other dogs, running along the beach and so on. You do need to be careful with puppies under 18 months or so; while they need exercise, it must not be forced or sustained. For example, you cannot take them jogging or biking with you until they are fully grown, or you will damage their joints
