PetsAdvisor recommends using dog nail clippers to cut the nail just above where it is broken if a dog's nail is falling off. If a clean cut is impossible, take the dog to a veterinarian for nail removal. Often, this procedure requires sedation as it is painful.
When cutting a dog's nails, PetsAdvisor recommends having a pet emergency kit nearby for your pet's safety. If the nail begins to bleed, apply styptic powder to the wound. The cauterizing agents in the powder rapidly stop bleeding.
Once the nail is removed and any bleeding stops, PetsAdvisor explains that it is time to clean and disinfect the area to prevent infection. To do this, wash your dog's paw in warm water. Then, apply pet antiseptic. If at any time the nail begins to bleed again, continue to apply styptic powder until the bleeding stops. Next, bandage the dog's paw. Wrap the paw in first aid tape, or place a sock over the wound before wrapping it up. If your dog tries to take the bandage off, purchase an E-collar to prevent your dog from causing itself further injury. Change the bandage daily, and wash the dog's paw before applying a new one.
