It completely depends on the terrain, the age the dog was started, how the dog was conditioned and most importantly GENETICS!
A lot of people recommend only free play, with small walks for puppies, to keep the stress on their bodies down. As they age, you slowly build up endurance and types of activities(hiking, swimming, jumping, running, biking etc). Waiting until joints are fully formed before repetitive activities are practiced is also key, young dogs need diversity in their exercise routines, to break up repetitive stress on joints (swimming being one of the best!). But one of the biggest components is going to be genetics. Having dogs bred from dogs that have low incidents of joint issues/malformations, is the best way to reduce your dogs chances of having them.
