i would get the bond right between youbefore you do much more hunting, your only going to get frustrated with the dog out,,take him out and just play ball with him, 2 tennis balls, throw one , then get him excited bout the other in your hand but dont throw it til he brings the other in , but dont take it off him just let him drop it, then sling the other one,
this play does 2 things it informs the dog that when he brings something to you your not going to claim it off him, and will open a channel of understanding between you 2, i would also call him by name when he's coming towards you for
