Lots of love, praise, play, and very gentle corrections and he'll warm up in no time at all.
Assuming he is 8 weeks old, take the 1st few weeks and just work on bonding with him. Get him started on the house training and used to the crate, if you decide to use one, which I highly recommend. Very short, gentle sessions on the leash, and you'll be fine.
He's going to learn more in the 1st month to six weeks with you than any other time in his life. Make the investment in his development during this time. Introduce him too as much as he can handle in very short sessions.
