When the female or female fails to release the puppies or kittens from the placenta (or, for example, it is not possible as with a caesarean section), we will have to assist her.
In most cases it will be enough to interrupt the blood flow in the umbilical cord by pinching with your nails and then cutting the umbilical cord with rounded scissors (not too close to the navel, the remainder will dry out and fall off by itself from the navel!).
Sometimes, however, it may be necessary (or according to personal preference) to first tie the umbilical cord with, for example, an artery clamp or suture before cutting it on the side of the placenta.
Boil after use or clean / disinfect completely with alcohol!
