anyone good with dogs? or trainers?

So we have had our first dog for 2.5 years now.



He is a very shy timid dog. But at the same time plays and loves to have my parents dog around and even one of my wifes family dog around.



We just got a new puppy, for one we wanted another, and two seeig how happy the first dog is around his friends....thought it would be good for him to have a buddy around the house all the time.



So its only been two days. New puppy is 9 weeks.



But the older one Is not happy, he is acting way out of the ordinary. Wont leave my side.....everything he does now is not his normal routine or his normal self. Puppy tried to play with older one....older is now growling....never has done that before to any person or other dog.



We really love the new dog....but if my other one doesn't get used to him or isn't hapy I will get rid of the puppy sad to say.. And the wife will not be happy at all.



Looking for insite or ideas on how to help the interactions better. And or how long do I give the older dog to come around before making a rash decision.
