Re your retriever, perhaps you could ask and reward Skippy for stepping up; then turn to your retriever and ask him/her to do something for a reward too... so they both have some attention and a bit of fun.
When Kobe got a little bold and snuck into Ollie's cage stole an almond, Ollie would lunge and/or growl at Kobe whenever he came near him afterwards. I began giving Ollie a piece of cashew when I carried Kobe over towards him and if he didn't growl. Pretty soon Ollie began to look forward to Kobe coming over as it meant he got a treat. Now they are fine together. Just be careful that you don't allow the dog to get too close to Skippy - somebody on another forum posted a horrendous photo of a dead Macaw which had been killed by his dog as a warning to others - the dog had somehow managed to get into the room and the bird had managed to get out of his cage.
What I did/do make sure with Kobe is to give him almost as much attention that he got before Ollie arrived... which was easy at the beginning as Ollie was totally hands off then. But Kobe has got used to Ollie getting progressively bolder and coming out of his cage now.
