Dawg53 has a good post somewhere about the method for getting tapeworm, but it is for Valbazen, not SafeGuard. For tapes you need to use a larger dose than usual. Normally you would give a pea-sized amount (or 1/2 ml) of SafeGuard, but I would give 2 or 3 times that, for 3 days in a row. Than repeat in 10 days for 3 straight days. Tapeworm is hard to get rid of, but is not an emergency--the other worms are what is important now. She may well be showing some symptoms of Mareks.
