produce more milk?

do you have a good whelping box with rails ? most losses are do to the gyps laying on the pups . I all ways just free feed my gyps all they want when they want it . and have them on a vitamin supplement . start feeding the pups at 3 weeks to help the gyp out . and make sure when you worm the pups that you trim them little fish hook toe nails back , they really work at them udders and will make the gyp plum miserable . most gyps will all ways have plenty of milk . it may not look like it but them teats don't have to be dragging the ground to be supplying milk .
