Best way is to be firm in setting your boundaries with your new dog from the beginning.
We have a new pup in our home as of June, now a 5 month old Rottie named
Bear
He has been good so far, at first it was exciting for him to see Liberty my BGM fly, and if he sat there long enough on my arm, Bear would be tempted to reach for his tail.
I let a firm "LEAVE IT" and push him away setting my boundaries around me for him to understand. We always distract with a verbal sound to get his attention if he may look like he will get into mischief.
Best to make sure your new pup is also exercised very well before letting your bird out, and of course monitor every moment they are both out. Crate your dog when he's not in your sight to prevent him from bothering him while in his cage.
When your dog gets older, he should have an understanding what you expect from him, and shouldn't have much problems. Just the puppy training part is the most time consuming and must follow through with consistancy.
My last Rottie was raised around an
English Angora Rabbit that was house trained, they got along great, and when we got our birds later, she never bothered them at all. If the birds happened to fly down while we were there, they would just walk by her and she never cared.
