I also have parrots ( 1 amazon, 1 blue and gold, 1 quaker, 1 canary and 1 budgie) and have found that I feel more comfortable that my dogs are afraid of the birds.
Would you want to take the chance? I also have to make sure my birds won't harm my puppies (I.E. Amazon & Blue &Gold)
In our house we keep seperate time for the birds and the dogs. I always go back to " it is better to error on the safe side".
If my puppies are sulking I just talk to them so they don't feel as bad and know they aren't being punished. Maybe give him a special treat or favorite toy during the time you have Ruby out.
