This is the blood vessel and is as far as you can go. If you reach the blood vessel and the spur is still too long then you will need to wait a few weeks for the blood vessel to withdraw a little from the end of the spur before trimming again. Using the file, you can round the edges of the spurs off to make them neat. If you trim too far, the spur will bleed and it will be very difficult to stop bleeding (just like dogs nails). You may want to consider buying a Veterinary Caustic (Silver Nitrate) Pencil.
Most states classify a standard DUI (or DWI) charge as a misdemeanor. Certain circumstances can raise the level of the charge to a felony, however. A conviction for a felony DUI carries stiffer penalties and more lasting consequences than a misdemeanor charge.
Misdemeanor vs. Felony Offenses. Misdemeanors: Misdemeanors are more serious than infractions. They are usually defined as a crime which is punishable by up to a year in jail time. Sometimes that jail time is served in a local county jail instead of a high security prison. Other states define a misdemeanor as a crime that is not a felony or an infraction. Prosecutors generally have a great degree of flexibility in deciding what crimes to charge, how to punish them, and what kinds of plea bargains to negotiate. Felonies: Felonies are the most serious types of crimes.
