Why forget the dummy? It's a great training aid, mental stimulation for the pup, builds the bond between man and dog, gets it entering cover willingly, gets it retrieving. List is endless.did this method work for you then?,not one lad I know with decent bushers has needed to adopt this method to encourage entering cover,I'd not worry about trying to say the right thing I'd just be getting it out every day,they ain't all smashing cover at 5 month he got plenty time yet for it to come good
