Every dog is different though. My labs i use to have never would hurt a bird and we were training them for hunting.I'm surprised you feel that way! After we had a dog kill one of our chickens after he hopped a fence it has been debilitating. I can't sleep, I can't even go a day without thinking if everything is secure. I assumed this was a universal experience. I will probably never own a hunting breed (specifically a lab) because of it. I am so overcome with worry that I do miss out on things! But I don't think it will ever change. I had never thought of it like that before.
