(Sorry I lost you for a moment but my mouse seems to have picked up a virus (a lot less painful than what you're dealing with).
I have never cut the quills.
This website will give you a blow-by-blow description of a recommended order of quill removal: http://www.associatedcontent.com/article/38189/removing_porcupine_quills.html?cat=53
Important points to remember:
-after you've removed the inner mouth quills, muzzle your dog, because this is a very painful procedure!
-don't worry about light bleeding
-after you are done, if you can hose Ranger down with a gentle spray of cold water, you will give him some pain relief and cleanse the wounds.
-use pliers or hemostats to pull the quills
If at all possible, take him to an emergency room to have them removed. It will be a long and painful process for the both of you.
