You don't walk a puppy until they have received all their puppy shot sets or they can get sick still. Your vet will tell you when it's okay to do things like that. You can ask them to explain why pups get so many sets of shots, the 'window of opportunity' and titer levels. :-) After that it depends on the dog and the breed. You don't want to overwork a breed prone to hip dysplasia or one that overheats easily or anything but they still need an appropriate outlet for their energy. Your breed parent club may be a good place to check into it as well.
