What is rick Rac ribbon. I always have this problem with identifying pups. with small litters say two of each sex I can usually tell who is who, if there is a white toe or something. I have had littters where they were impossible to tell apart and did resort to cutting out the fur, but would rather not.
Being dark marker is useless.
I did use wool wioth a piece of elastic on a recent litter. Wrote the ID on the elastic with laundry marker, but eventually they kept geting them off each other.
