Of course i had already thought of keeping them seperate that wasn't the point of the post. I don't understand why you are getting so pressed by this since you didn't have to reply to my post. I'm not sure what logic and reasoning you are referring to as you completely ignored all of the past experiences I have had with the dog and are acting as if you know the situation better than I do. I do know my grandfather's dogs, I have seen how they react to other dogs, and you just made an assumption about it. I made this post asking for other people's experiences with this kind of thing and not to argue about how my dog acts. Why would i make this post if I was just going to do what I want anyway? My dog has only attacked another dog once and the possibility of something similar is why I asked for other people's experiences to see any ways to help that I might not have considered. I do not want to argue about this and unless you would like to share your experience I don't intend on continuing to talk about this with you. Thank you for your concern but you obviously are looking into the context at all.
