In my opinion this is still a very risky move. animals will be animals and they will act on instincts. If you do decide to have them out together make sure you have them under a very watchful eye. All it takes is one small puncture of the skin and your bird can be in big trouble since the saliva of mammals is very dangerous to birds since there is so much bacteria in their mouth. And with larger birds you have to keep in mind the safety of the dog their beaks can do some serious damage(I am speaking from experience) So just keep this all in mind when you decide to keep them in the same room together.
