If the quick is accidentally cut during grooming, the area must be compressed for at least two minutes. Some groomers find that applying styptic powder is the most common and efficient way to stop the bleeding, so keep some on hand if you’re a first-timer.  Make sure to keep it clean after walks to prevent infection, and take your dog to the vet if it becomes infected. An infected nail is soft, brittle, swollen, inflamed, may bleed or discharge, and dogs may lick or chew the affected area.
