Yes.
alot
don't hurt them leave them alone
Nothing at all -- it's not an English saying. Perhaps you mean "take a hard-nosed position," which means to take a stubborn position and refuse to yield even if someone ends up getting hurt by your actions.
Don't no
All piercings hurt to some degree. For some people it may hurt more than others. Just make sure that you get your piercing done by a professional and they will be sure it gets done right.
It will if not done right
Yes.
It could possibly hurt you if the dog bites you. It won't hurt the dog if done correctly.
Piercings done with a piercing gun can hurt for several days after the piercing has been done. Piercings done by a professional body piercer using needles generally only hurt momentarily and off and on (twinges) for 24 hours post piercing.
Another black nosed Pitbull.
All piercings hurt for long if done by someone unprofessional. If you get it done at a shop it doesn't hurt much after. If you get one make sure you clean the piercing everyday as well as the hole
If you just got it done, yes it will hurt.
