At the minuet Dan just keep it fun and build up the bond with him, he will then want to work for you when he is more mature and the real training can begin, i know my old GWP was about a year before he was mature enough to take on serious training, but a lab could only be 5 or 6 months, so the all mature at different time, just dont rush him.
I would like to add,what a bonnie pup he looks and i am looking forward to future posts about him.
