Generally, the location of the blood line cannot be seen clearly with the naked eye on a dog's black nails. You can use light to place it close to the dog's nail. If the inner core of the dog's nail is transparent, the blood line can be seen clearly. If your dog’s nails are pure black, you can only roughly estimate the location of the blood line. The location of the dog's blood line is generally about 3 mm forward from the bend of the dog's nail, but if the dog's nails are not trimmed frequently, the blood line may be extended.

How to trim dog’s black nails

1. If the nails are not very long, the owner can use a nail polisher to cut the sharp parts of the dog’s nails. Polished and rounded.

2. The owner can trim it little by little, in small amounts many times, until a white core appears in the dog's nails, then stop.

3. If you accidentally cut your nails and bleed, just press with a tissue to stop the bleeding, and then disinfect them.
