I think the big thing with mature dogs and puppies is to let the older dog set the tone with the puppy and to let them figure out their relationship. Expect grumbling and some noisy "Back off!" messages from Savannah, but as the puppy grows, their interaction will be different. Savannah will probably be a little stressed out by this new addition, so make sure that Savannah has some puppy-free time by using the crate with the puppy and by taking Savannah for walks individually every now and then. Puppy will also benefit from one-on-one time with you for short training sessions.
