Hello mate, teach her to hold the dummy, open her mouth, place the dummy in it and tell her to hold, press her mouth shut gently, do it for a couple of seconds and slowly increase the time, press slightly harder if needs be, always repeat " hold", get her carrying it saying hold. Do your retrieve training in a passage, so she can't run away and mess about, when she picks the dummy up, tell her hold and call her in , reward with praise and titbit.
Good luck
