I dont know much about this kind of thing but I would think just them being around each other and getting used to each other with someone there to stop anything if it happens would be enough.
I think it also depends what territory you are in. If its your dogs territroy and you are worried that it might hurt the puppy, you could put it in a mesh cage or something for little periods of time so your dog can get used to it and not hurt the puppy.
