The stuff you put on if you cut the nails too far back is Quick Stop and can be purchased at any pet store. When my yorkies nails get too long, I cut them back & when you look at the end of the nail after it's cut, look for a dark dot, about the size of a pencil point, when you see that stop cutting, if you go any more you will hurt them. Then I wait about a week & trim again, the vein will slowly recied(sp?) and before long you have perfect nails.
