This is the perfect opportunity to socialize this little guy
hold the puppy in you lap and have the older dog come into the room
Pet the puppy and hold a treat in your other hand
call him over
do give him the treat let him sniff it and entice him closer and closer to the puppy
Give the puppy and him a piece of the treat and tell him what a good boy he is
.... and give him more treats the more he interacts with the puppy
little by little he'll get the idea that when the puppy is around he gets good stuff
