: If I use his name when I'm out hunting and I want to send him off to retrieve : a duck, won't that confuse him then if we are at the house and I call his name : to get him to come?
If he's only 4 months old, you should be able to change a command with no real problem. Start using both commands. If he knows what hunt means, and you want to use xxx, then use both commands, i.e. hunt, xxx, gradually using hunt less, and xxx more.
I have three GSPs, so most of my commands consist of two words, first the dogs name, then the command. That way they know which one I'm talking to, plus it's an attention getter. i.e. Spike, NO!. So Spike knows I'm talking to HIM, and he's now listening when I say NO!. You could make the release command something like SPIKE, OK. Then if you have two dogs, only Spike knows he can go.
Of course, this works better with MY dog, as his name is Spike.
