It usually takes 1 to 2 days for a dog to recover after cutting to the blood line. If not treated, it may lead to secondary infection, which will prolong the recovery time. After cutting the dog's blood line, you need to apply iodophor to disinfect the wound, and you can also apply antibacterial and anti-inflammatory ointment.

We can use a focused flashlight to shine on the dog's nails. We can see a pink blood line, and then just cut off the tip beyond the blood line. If the dog's nails are black or dark, we need to cut them slowly. First, cut off less than one-third of the nails, and then use a nail file to smooth the section.
