I have lab mix, border collie mix, and great pyrenees. The lab had to be taught not to mess with the birds. The border collie was great from the beginning. The great pyrenees, she is still only seven months but she did kill a couple of birds a few months ago. We had to work with her as we did the lab to train her that was not acceptable. All seems fine now.
So training, training, and training whatever you decide on.
