I really don't know of any effect, either positive or negative. I would think, and have personally experienced, imprinting a pup when teething and have had no problems. Play tug, developing prey drive, calmness and a little focus is what I'm speaking of. Like Matt said, I don't think anyone said, nor do I advocate pushing a pup or young dog for that matter, to any sort of limit. Not even close. Keeping it positive and prey based play type of stuff has no negative effect that I can anticipate. Unless you (not you personally Storm) get a little squeamish about seeing a bloody tug, rag, etc.. :D :D :D
