Teach it to hold the dummy on the command "hold" by placing the dummy in its mouth and gently hold it shut, saying hold, keep doing this until it holds on command it works, then when retrieving as it comes in say hold, until you are ready to take it off it and use another command for release, dead or ta, whatever. Good luck.
