Are you saying that you don't know the nerve strength of your 5 month-old-mid-teetheing puppy before you play a game of tug?? Of course you do!
Daily LIFE tells you a lot more about their character and nerve than anything.
Chances are good if you're walking around with a puppy attached by the mouth to your pant leg for a good portion of the day; you're not going to see problems with a little game of "pull this rag then win it".
