Sorry to hear Teddy is stressed by the new puppy sibling.
Try to keep Teddy's previous routine intact as much as possible. Does he like walks and outings? Take him out alone, daily if needed.
Boss is 5 months old, correct? In addition to taking Teddy out alone, walk them together.
Does Teddy do tricks? Practice doing tricks together. My boys know only a few simple tricks, but performing them together helped forge a bond.
We had a few jealousy issues the first few weeks. Max wouldn't let our Teddy share his car seat or the bed. Extra outings alone with Max and together with Teddy helped.
Most of all, remain calm. Keep a positive attitude or Teddy will pick up on your anxiety and it will feed his stress.
