Make sure you have some kind of styptic powder or pencil around in case you cut too deeply and cause the vein to bleed.
There are several brands of styptic on the market these days, and you can get this at any pet supply store.
If you accidentally cut the quick, styptic powder will stop the bleeding and alleviate the pain.
Apply a styptic powder to the wounded area if the quick is cut to immediately stop bleeding.
It usually looks worse than it is; that's why you have styptic powder on hand.
Styptic powder is important to have on hand while clipping your dog's nails.
Some examples of styptic powder are Kwik-Stop and CutStop.
Immediately place styptic power on the nail.
Medicinally, gallic acid has been, and is still, largely used as an astringent, styptic and haemostatic. Gallic acid, however, does not coagulate albumen and therefore possesses no local astringent action.
