Stop worrying about your birds and train your dog to L I S T E N to you! I have had to retrain my 50 pound border collie mix (Rose) NOT to grab the horses by the tail to stop them!!!! It IS possible. First, I agree with the post about leash training. Next, train your dog to sit. My 2 dogs will sit when I tell them to, as when someone is driving in or out of the driveway. (NOBODY wants to run over your dog!) Next, train your dog to stay. Loyal dogs want to run back to be with you, but if a busy road is in the way, they'll be hit and killed. e o s (end of story, for those who didn't know)
Your dog will think the training is playtime with YOU! My (other)dog, Pygma will go outside before I'm dressed for chores and wait for me. It's the same game every day--She dances around me and says, "Pyg loves you, Duck!!! C'mon, Duck---play with your Pyg!!" As your dog gets older, the training sessions can get longer and longer. If you persist and do lots and lots of verbal rewarding, everybody is gonna wonder why they didn't get your breed of dog.
