Pups seem to want to chew random household things until they are about two so try not to give him the opportunity if you can keep shoes and other things out of his reach, he should start loosing his needle like puppy teeth soon. Go ahead and start playing fetch with him now just keep it fun and not serious, also start working on basic commands sit/stay/no/fetch etc. If anyone you know has any leftover frozen gamebird wings start leaving him scent trails and hiding them to let him find them and praise him for it...just don't let him chew wings up, you can keep refreezing the wings in a freezer bag they will last a long time that way. Training new pups is fun as you see them start "getting it" like a light goes on in their head when they understand and start working with you. Keep training session short for now and stop as soon as he starts getting disinterested...plenty of time for serious training when he is a little older, keep it fun for both of you.
Great looking pup!
